Hybrid starch/silica films with improved mechanical properties

Abstract Environmental concern has increased the research in development of biodegradable packaging. Although there are many reports about starch films, their physicochemical properties need to be improved, and the introduction of an inorganic compound is an alternative to be applied. However, there...

520			\|a Abstract Environmental concern has increased the research in development of biodegradable packaging. Although there are many reports about starch films, their physicochemical properties need to be improved, and the introduction of an inorganic compound is an alternative to be applied. However, there are few reports about the development of biodegradable hybrid organic–inorganic films for food packaging. Therefore, the preparation of biodegradable films was proposed by using sol–gel and casting techniques, based on starch and glycerol as plasticizers, with the incorporation of an alkoxide precursor containing silicon, TEOS (tetraethyl orthosilicate) in different concentrations. Morphological, thermal, optical, and mechanical properties, water solubility, swelling, and water vapor permeability were evaluated. The addition of TEOS was more efficient when it underwent pre-hydrolysis before incorporation into the film-forming solution, significantly interfering with the results of mechanical, optical, and barrier properties. The silica phase was uniformly incorporated into the polymer, presenting micrometric domains. The hybrid films produced have satisfactory properties for application as biodegradable packaging.
520			\|a Highlights The addition of silica moiety increased by up to 109% the tensile strength of hybrid films.Other properties of the hybrid films were also improved with the addition of silica microdomains.Better biodegradable film properties will open new possibilities for use like rigid package.

Although there are many reports about starch films, their physicochemical properties need to be improved, and the introduction of an inorganic compound is an alternative to be applied. However, there are few reports about the development of biodegradable hybrid organic–inorganic films for food packaging. Therefore, the preparation of biodegradable films was proposed by using sol–gel and casting techniques, based on starch and glycerol as plasticizers, with the incorporation of an alkoxide precursor containing silicon, TEOS (tetraethyl orthosilicate) in different concentrations. Morphological, thermal, optical, and mechanical properties, water solubility, swelling, and water vapor permeability were evaluated. The addition of TEOS was more efficient when it underwent pre-hydrolysis before incorporation into the film-forming solution, significantly interfering with the results of mechanical, optical, and barrier properties. The silica phase was uniformly incorporated into the polymer, presenting micrometric domains. The hybrid films produced have satisfactory properties for application as biodegradable packaging. Highlights The addition of silica moiety increased by up to 109% the tensile strength of hybrid films.Other properties of the hybrid films were also improved with the addition of silica microdomains.Better biodegradable film properties will open new possibilities for use like rigid package.

Although there are many reports about starch films, their physicochemical properties need to be improved, and the introduction of an inorganic compound is an alternative to be applied. However, there are few reports about the development of biodegradable hybrid organic–inorganic films for food packaging. Therefore, the preparation of biodegradable films was proposed by using sol–gel and casting techniques, based on starch and glycerol as plasticizers, with the incorporation of an alkoxide precursor containing silicon, TEOS (tetraethyl orthosilicate) in different concentrations. Morphological, thermal, optical, and mechanical properties, water solubility, swelling, and water vapor permeability were evaluated. The addition of TEOS was more efficient when it underwent pre-hydrolysis before incorporation into the film-forming solution, significantly interfering with the results of mechanical, optical, and barrier properties. The silica phase was uniformly incorporated into the polymer, presenting micrometric domains. The hybrid films produced have satisfactory properties for application as biodegradable packaging.</subfield></datafield><datafield tag="520" ind1=" " ind2=" "><subfield code="a">Highlights The addition of silica moiety increased by up to 109% the tensile strength of hybrid films.Other properties of the hybrid films were also improved with the addition of silica microdomains.Better biodegradable film properties will open new possibilities for use like rigid package.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Biodegradable films</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Packaging</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Mechanical properties</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Organic–inorganic films</subfield><subfield code="7">(dpeaa)DE-He213</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Pagno, Carlos Henrique</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Flores, Simone Hickmann</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Costa, Tania Maria Haas</subfield><subfield code="e">verfasserin</subfield><subfield code="4">aut</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="t">Journal of sol gel science and technology</subfield><subfield code="d">Dordrecht [u.a.] : Springer Science + Business Media B.V, 1993</subfield><subfield code="g">95(2020), 1 vom: 23.

title_auth	Hybrid starch/silica films with improved mechanical properties
abstract	Abstract Environmental concern has increased the research in development of biodegradable packaging. Although there are many reports about starch films, their physicochemical properties need to be improved, and the introduction of an inorganic compound is an alternative to be applied. However, there are few reports about the development of biodegradable hybrid organic–inorganic films for food packaging. Therefore, the preparation of biodegradable films was proposed by using sol–gel and casting techniques, based on starch and glycerol as plasticizers, with the incorporation of an alkoxide precursor containing silicon, TEOS (tetraethyl orthosilicate) in different concentrations. Morphological, thermal, optical, and mechanical properties, water solubility, swelling, and water vapor permeability were evaluated. The addition of TEOS was more efficient when it underwent pre-hydrolysis before incorporation into the film-forming solution, significantly interfering with the results of mechanical, optical, and barrier properties. The silica phase was uniformly incorporated into the polymer, presenting micrometric domains. The hybrid films produced have satisfactory properties for application as biodegradable packaging. Highlights The addition of silica moiety increased by up to 109% the tensile strength of hybrid films.Other properties of the hybrid films were also improved with the addition of silica microdomains.Better biodegradable film properties will open new possibilities for use like rigid package.
