Green chemistry and green engineering concepts have been combined to develop novel sustainable polymeric materials. Solvent free photocurable acrylate resins with biorenewable carbon content of 75%–82% suitable for application in DLP 3D printing technology were composed by commercially available bio‐based materials, acrylated epoxidized soybean oil (AESO), isobornyl methacrylate (IBOMA), methacrylic ester (ME), tetrahydrofurfuryl acrylate (THFA), and tetrahydrofurfuryl methacrylate (THFMA). They demonstrated high printing accuracy and good adhesion between layers. The monitoring of photocross‐linking kinetics of high biorenewable content acrylate photoresins by the real‐time photorheometry and analysis of their rheological parameters was carried out. Synthesized polymers exhibited high yield of insoluble fraction and thermal decomposition temperature at the weight loss of 10% above 300°C. Polymers AESO/IBOMA and AESO/THFMA showed the highest values of tensile modulus and tensile strength. Biodegradability of the synthesized polymers AESO/ME, AESO/THFA, and AESO/THFMA was investigated by measuring oxygen consumption in a closed respirometer. Such AESO‐based polymers can be a competitive solution to replace petroleum‐derived polymeric materials in additive manufacturing and reduce the environmental impact.

用于DLP 3D打印的高生物可再生含量的丙烯酸酯光固化树脂

绿色化学和绿色工程概念已经结合在一起，以开发出新型的可持续聚合物材料。适用于DLP 3D打印技术的，可生物再生碳含量为75％–82％的无溶剂光固化丙烯酸酯树脂，由市售的生物基材料，丙烯酸酯化的环氧大豆油（AESO），甲基丙烯酸异冰片酯（IBOMA），甲基丙烯酸酯（ ME），丙烯酸四氢糠酯（THFA）和甲基丙烯酸四氢糠酯（THFMA）。他们证明了高印刷精度和良好的层间附着力。通过实时流变法监测高生物可再生含量的丙烯酸酯光树脂的光交联动力学并对其流变参数进行分析。合成的聚合物在300℃以上失重10％时表现出高产率的不溶级分和热分解温度。聚合物AESO / IBOMA和AESO / THFMA显示出最高的拉伸模量和拉伸强度值。合成聚合物AESO / ME，AESO / THFA和AESO / THFMA的生物降解能力是通过在封闭的呼吸计中测量氧气消耗量来研究的。此类基于AESO的聚合物可以成为竞争性解决方案，以替代增材制造中源自石油的聚合材料并减少对环境的影响。AESO / THFMA通过在封闭的呼吸计中测量氧气消耗进行了研究。此类基于AESO的聚合物可以成为竞争性解决方案，以替代增材制造中源自石油的聚合材料并减少对环境的影响。AESO / THFMA通过在封闭的呼吸计中测量氧气消耗进行了研究。此类基于AESO的聚合物可以成为竞争性解决方案，以替代增材制造中源自石油的聚合材料并减少对环境的影响。
