Keratins extracted from Merino wool and Brown Alpaca fibres as potential fillers for PLLA-based biocomposites
Abstract This paper reports on the promising perspectives of using keratins extracted by sulphitolysis reaction from Merino wool (KM) and Brown Alpaca fibres (KA) in poly (l-lactide) (PLLA)-based biomaterials. Both types of keratin were dispersed in chloroform ($ CHCl_{3} $) and tetrahydrofuran (THF...

| 520 | |a Abstract This paper reports on the promising perspectives of using keratins extracted by sulphitolysis reaction from Merino wool (KM) and Brown Alpaca fibres (KA) in poly (l-lactide) (PLLA)-based biomaterials. Both types of keratin were dispersed in chloroform ($ CHCl_{3} $) and tetrahydrofuran (THF), and optimisation of dispersion methods and parameters using the two selected solvents was considered. The extraction yield, as well as supermolecular structures, morphology and thermal behaviour of the two proteins before and after the regeneration in $ CHCl_{3} $ was investigated. The results indicated that the supermolecular structures and thermal behaviour of the two proteins were affected by the interaction with $ CHCl_{3} $, producing decrease of the amount of α-helix structures in KM and an increase for KA, a slight decrease of β-sheet structures and a reduced thermal stability of α-crystallites for both keratins. Biocomposite films based on PLLA polymer matrix and two different contents of Merino wool and Brown Alpaca keratins (1 % and 5 % wt) were successfully developed by solvent casting in chloroform and the resulting morphologies after incorporation of different keratins (as a function of content and source) give evidence of different surface topographies, with a random distribution of keratin in flask-like structure. PLLA/5KA and PLLA/5KM samples with 1 % and 5 % wt of keratins show a specific pore-like surface microstructure, induced by solvent evaporation. | ||

The extraction yield, as well as supermolecular structures, morphology and thermal behaviour of the two proteins before and after the regeneration in $ CHCl_{3} $ was investigated. The results indicated that the supermolecular structures and thermal behaviour of the two proteins were affected by the interaction with $ CHCl_{3} $, producing decrease of the amount of α-helix structures in KM and an increase for KA, a slight decrease of β-sheet structures and a reduced thermal stability of α-crystallites for both keratins. Biocomposite films based on PLLA polymer matrix and two different contents of Merino wool and Brown Alpaca keratins (1 % and 5 % wt) were successfully developed by solvent casting in chloroform and the resulting morphologies after incorporation of different keratins (as a function of content and source) give evidence of different surface topographies, with a random distribution of keratin in flask-like structure. PLLA/5KA and PLLA/5KM samples with 1 % and 5 % wt of keratins show a specific pore-like surface microstructure, induced by solvent evaporation.</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">PLLA</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Wool Fibre</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Pigment Granule</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Supermolecular Structure</subfield></datafield><datafield tag="650" ind1=" " ind2="4"><subfield code="a">Neat PLLA</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Tonetti, C.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Rombaldoni, F.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Puglia, D.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Fortunati, E.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Armentano, I.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Santulli, C.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Torre, L.</subfield><subfield code="4">aut</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kenny, J.

Keratins extracted from Merino wool and Brown Alpaca fibres as potential fillers for PLLA-based biocomposites |
| abstract |
Abstract This paper reports on the promising perspectives of using keratins extracted by sulphitolysis reaction from Merino wool (KM) and Brown Alpaca fibres (KA) in poly (l-lactide) (PLLA)-based biomaterials. Both types of keratin were dispersed in chloroform ($ CHCl_{3} $) and tetrahydrofuran (THF), and optimisation of dispersion methods and parameters using the two selected solvents was considered. The extraction yield, as well as supermolecular structures, morphology and thermal behaviour of the two proteins before and after the regeneration in $ CHCl_{3} $ was investigated. The results indicated that the supermolecular structures and thermal behaviour of the two proteins were affected by the interaction with $ CHCl_{3} $, producing decrease of the amount of α-helix structures in KM and an increase for KA, a slight decrease of β-sheet structures and a reduced thermal stability of α-crystallites for both keratins. Biocomposite films based on PLLA polymer matrix and two different contents of Merino wool and Brown Alpaca keratins (1 % and 5 % wt) were successfully developed by solvent casting in chloroform and the resulting morphologies after incorporation of different keratins (as a function of content and source) give evidence of different surface topographies, with a random distribution of keratin in flask-like structure. PLLA/5KA and PLLA/5KM samples with 1 % and 5 % wt of keratins show a specific pore-like surface microstructure, induced by solvent evaporation. © Springer Science+Business Media New York 2014 |
