Synthesis and Application of Soybean Oil-based Photocurable Resin for High-resolution 3D Printing
摘要
Abstract
Stereolithography 3D printing technology has been widely employed in fields such as wearable devices,the electronics industry,and bioengineering due to its ability to fabricate intricate structures.However,commercial photocurable resins primarily rely on petroleum-based raw materials,which not only pose environmental challenges but also suffer from issues including poor biocompatibility and insufficient degradability.Photocurable resins derived from renewable resources such as vegetable oils have garnered significant attention in recent years;however,limitations such as insufficient mechanical properties,poor thermal stability,and low curing speed continue to restrict their practical applications.To address these challenges,this study utilized epoxidized soybean oil(ESO),itaconic anhydride(IA),and hydroxyethyl methacrylate(HEMA)as the primary raw materials to synthesize a soybean oil-based photocurable prepolymer(IESO)with high double-bond density through a green process.The synthesis process of IESO has the following green features:it does not require solvents,utilizes plant-derived raw materials,is free of volatile organic compounds(VOCs),and exhibits a high atom utilization rate.IESO outperforms AESO and other plant oil-based photocurable resins in tensile strength and thermal properties while maintaining a high bio-based content.Moreover,IESO resin can be used for 3D printing to fabricate high-precision structures.This study offers insights into the advancement of high-performance and sustainable 3D printing photocurable materials.关键词
