Two frontal polymerization (FP) mechanisms, frontal ring-opening metathesis polymerization (FROMP) of dicyclopentadiene and frontal radical polymerization (FRaP) of benzyl acrylate and hexanediol diacrylate, were combined for rapid manufacturing of welded thermoset materials. Leveraging the immiscibility of the two different FP resins, welded thermosets and gradient foams of varying composition were achieved by switching of FP mechanisms. The adhesion strength of the welded thermoset materials differed depending on the originating mechanism. Finally, welded thermoset foams of varying porosity and homogeneity were generated through initiation from the bottom of the two resins.

切换正面聚合机制:FROMP 和 FRaP

将两种正面聚合 (FP) 机制,即双环戊二烯的正面开环复分解聚合 (FROMP) 和丙烯酸苄酯和二丙烯酸己二醇的正面自由基聚合 (FRaP) 相结合,用于快速制造焊接热固性材料。利用两种不同 FP 树脂的不混溶性,通过切换 FP 机制实现了不同成分的焊接热固性塑料和梯度泡沫。焊接热固性材料的粘合强度因起源机制而异。最后,通过从两种树脂的底部引发,产生了不同孔隙率和均匀性的焊接热固性泡沫。
