Effect of graphene oxide on photo- and thermal curing of chalcone–based benzoxazine resins
Benzoxazine monomer containing chalcone moiety was prepared through Mannich condensation reaction. The monomer and monomer mixed with different ratios of graphene oxide were exposed to UV irradiation followed by thermal curing to produce pristine thermoset and nanocomposites, respectively. The monom...

| 520 | |a Benzoxazine monomer containing chalcone moiety was prepared through Mannich condensation reaction. The monomer and monomer mixed with different ratios of graphene oxide were exposed to UV irradiation followed by thermal curing to produce pristine thermoset and nanocomposites, respectively. The monomers, pristine thermoset and nanocomposites were characterized by analytical techniques such as 1H-NMR, 13C-NMR, FTIR, SEM and XRD. The peak characteristic to oxazine ring disappeared in the pristine thermosets and nanocomposites confirming successful ring-opening polymerization. The (001) plane in GO was not observed in the nanocomposites revealing the dispersion of graphene layers in the polymer matrix, and the dispersion was confirmed by SEM examination. The thermal properties using TGA and DSC indicate that the presence of graphene oxide catalyzes the ring-opening of oxazine and decreases the curing temperature up to 80 °C compared with pure benzoxazine monomer. In addition, the nanocomposites exhibit higher thermal stability and electrical conductivity compared with the pristine thermoset. Graphic abstract | ||

The monomer and monomer mixed with different ratios of graphene oxide were exposed to UV irradiation followed by thermal curing to produce pristine thermoset and nanocomposites, respectively.

The monomer and monomer mixed with different ratios of graphene oxide were exposed to UV irradiation followed by thermal curing to produce pristine thermoset and nanocomposites, respectively. The monomers, pristine thermoset and nanocomposites were characterized by analytical techniques such as 1H-NMR, 13C-NMR, FTIR, SEM and XRD. The peak characteristic to oxazine ring disappeared in the pristine thermosets and nanocomposites confirming successful ring-opening polymerization. The (001) plane in GO was not observed in the nanocomposites revealing the dispersion of graphene layers in the polymer matrix, and the dispersion was confirmed by SEM examination. The thermal properties using TGA and DSC indicate that the presence of graphene oxide catalyzes the ring-opening of oxazine and decreases the curing temperature up to 80 °C compared with pure benzoxazine monomer. In addition, the nanocomposites exhibit higher thermal stability and electrical conductivity compared with the pristine thermoset.

effect of graphene oxide on photo- and thermal curing of chalcone–based benzoxazine resins |

Effect of graphene oxide on photo- and thermal curing of chalcone–based benzoxazine resins |
| abstract |
Benzoxazine monomer containing chalcone moiety was prepared through Mannich condensation reaction. The monomer and monomer mixed with different ratios of graphene oxide were exposed to UV irradiation followed by thermal curing to produce pristine thermoset and nanocomposites, respectively. The monomers, pristine thermoset and nanocomposites were characterized by analytical techniques such as 1H-NMR, 13C-NMR, FTIR, SEM and XRD. The peak characteristic to oxazine ring disappeared in the pristine thermosets and nanocomposites confirming successful ring-opening polymerization. The (001) plane in GO was not observed in the nanocomposites revealing the dispersion of graphene layers in the polymer matrix, and the dispersion was confirmed by SEM examination. The thermal properties using TGA and DSC indicate that the presence of graphene oxide catalyzes the ring-opening of oxazine and decreases the curing temperature up to 80 °C compared with pure benzoxazine monomer. In addition, the nanocomposites exhibit higher thermal stability and electrical conductivity compared with the pristine thermoset.
