One paper was published online in Polymer
Recently, one paper titled as “Fully recyclable and high performance phenolic resin based on dynamic urethane bonds and its application in self-repairable composites” was published online in Polymer, which co-authored by Xiaoqin Liu, Yu Li, Xiaolong Xing, Guanjun Zhang, Xinli Jing.
A fully recyclable phenolic resin (TDNR) with dynamic cross-linked network was facilely prepared without any catalyst using commercial novolac and toluene diisocyanate by forming hindered urethane bonds. The exchangeable network of TDNR ensures good processibility for long fiber prepregs, which are suitable for hand molding and reshape of composites. By utilizing a simple chemistry mechanism, the close-loop recycle of phenolic resin with high working temperature and good mechanical properties are successfully achieved.(Written by Zhen Wang; proofread by Xiaolong Xing)
