        越 越 more coating material, 包括清漆 and printing ink, and filling material, is use UV curable. is method made uniform polymer 网络, but also material is property, this made light polymer in printing, material and micro electronics and other field/area application. in Angewandte Chemie期刊 upper, research 人员提出 一 types new methods, types methacrylic acid ester, made uniform crosslinked tough polymer made as methods, make in high separation rate lower 进行 3D printing.

         UV curable usually is types 自由基链 polymerization. agent by light can separation understanding formed 自由基, 并攻击 mono 体, ethylene in C=C di 键, formed new 自由基, through more more mono and its combined formed is polymer 网络生 long 起点.

         control 自由基 light polymerization new methods and improvement product material property 质, 往往会 decrease slow solid process, this for/regarding 3D printing 说并不理想. short stage/phase for/regarding high separation rate and production time is important.

        维也 nano technology large 学(奥 利) Robert Liska领导 research small development types new methods, 基于 methacrylic acid ester light polymer 而不会抑 made solid process. use ester active ethylene acid ester （EVS） as is 链转移 agent, is it can easy from its 自身 一部 separation upper separation 离以激 active process.

         if growth polymer 网络攻击EVS而不 is types mono 体, 则会形 formed in 间体, speed separation formed in polymer and high reaction property 基团(甲苯磺酰基), this also 会引发 new reaction. add EVS越 more, polymer 网络 平均链 long short. due to relatively short polymer maintain relatively long property, therefore in solid process in shrinkage 导致裂缝 危险显 reduce . and 常规链转移 agent versus 反, in new methods in polymerization 不受抑 made, is in stability in or can reaction steps, therefore separation 离出甲苯磺酰基 is has 利.

         is testing it, research use methacrylic acid ester copolymer similar sample structure. thick degree is 50μm, in 各 层 in structure in very good separation 辨. material non uniform, solid tool has elastic property and impact resistant property, tool has high tensile strength. can through more add EVS数 amount adjustment this property. has EVS, material 就会太脆, method 进行 3D printing. this type of new methods can made 备出坚 tough light polymer used for material application, used for 组织生 long and filling 形状记忆 polymer.
