Enhancement of Self-healing Properties of Epoxy Vitrimer Using metal nanoparticle modified graphene |
| 초록 |
General thermosetting polymers have better physical properties than thermoplastic polymers, but are difficult to recycle. Recent studies have reported a thermosetting polymer called vitrimer that can be recycled using the transesterification reaction. Vitrimer has a temperature called topology freezing transition-temperature(Tv) at which the bond exchange is activated. Vitrimer can be reshaped above Tv.. Activation of transesterification is known to be possible only at high temperatures. So we added graphene with a photothermal effect for light activation. The added graphene was modified by metal nanoparticles to enhance the photothermal effect. The thus synthesized vitrimer is activated by transesterification through IR and exhibits self-healing properties. The vitrimer synthesized in this study will improve the applicability to the polymer coating and recycling polymer field. |
