Abstract
AbstractGraphene oxide has the characteristics of high specific surface area, high strength, and high modulus. The tensile and compressive properties of the cured resin part can be reinforced after the graphene oxide is mixed into the photosensitive resin. A self‐developed liquid crystal display (LCD) mask photo‐curing machine is adopted to prepare photosensitive resin parts mixed with graphene oxide. The influence of graphene oxide content on the surface roughness, tensile, and compressive properties of the cured resin is analyzed by the combination of finite element simulation and experiment. It is concluded that the accumulation of graphene oxide is the main reason affecting the tensile and compressive properties of the cured part. By applying ultrasonic vibration and extending the time of magnetic stirring at 80°C, the dispersion uniformity of graphene oxide is improved, the agglomeration of graphene oxide is reduced, and the tensile and compressive strength of cured parts are strengthened.
