▎ 摘 要
NOVELTY - A graphene oxide/light-cured composite resin is formed by dispersing graphene oxide in two-phase photocurable resin. The content of dispersed graphene oxide is 0.1-1 wt.%, with respect to content of composite resin. The photocurable resin comprises oligomer and photoinitiator. USE - Graphene oxide/light-cured composite resin is used in stereolithography rapid prototyping (claimed). ADVANTAGE - The graphene oxide/light-cured composite resin has increased breaking extending rate, maximum bending strain, high impact strength and excellent mechanical property. The stereolithography rapid prototyping is efficiently carried out using graphene oxide/light-cured composite resin in the scanning power of 200-850 mV and scan speed of 1000-6000 mm/s. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene oxide/light-cured composite resin. Graphene oxide is dissolved in a solvent, to obtain graphene oxide suspension. Oligomer and solvent are mixed in the ratio of 1:1, and dissolved to obtain oligomer/solvent mixture. The obtained graphene oxide suspension and oligomer/solvent mixture are mixed, ultrasonically cleaned for 0.5-36 hours, magnetically stirred at 20-40 degrees C, and photoinitiator/solvent solution of photoinitiator and photocurable resin are added in the mass ratio of 0.01-0.1, evaporated and the mixture was stirred to obtain graphene oxide/photocurable resin composite.
