摘要
前端聚合(frontal polymerization,FP)是一种以自身反应热为推动力,通过局部反应区域在反应物中连续的移动从而将单体转变为聚合物的新型反应模式。只需在反应的初始阶段进行短时间的加热,然后停止加热,即可借助放热反应的热自催化作用完成整个体系的聚合过程。本文旨在对前端聚合反应过程中的自驱动化学波进行调控利用。发现可以将化学能转化为机械能,从而在微反应器中将目标材料运输至指定位置实现反应。在恒温恒湿箱中制备叔碳酸乙烯酯(VeoV a 10)与丙烯酸羟丙酯(HPA)共聚的水凝胶基底(P(HPA-co-Veo Va 10))。用微流体法制备丙烯酰胺(AAm)与N-乙烯基吡咯烷酮(NVP)共聚的凝胶微球作为模拟货物。将制备好的凝胶基底置于丙烯酸羟乙酯(HEA)与交联剂、引发剂混合的溶液中溶胀一定时间,取出后将凝胶微球置于基底的一侧,用电动热风枪加热这一端30s后停止加热,随着前端端面的推进,微球也随之不停移动,微球的移动速率可以通过改变引发温度很好的控制,这就实现了化学能向机械能的转化。
Frontal polymerization(FP) is a new kind of mode in which monomers convert into polymer via a localized reaction zone that propagates through the reactor. As an efficient and rapid technique in polymer chemistry, FP has been extensively studied to synthesize various polymers and polymeric networks. In this work, we developed a novel autonomous conveyer gel driven by frontal polymerization(FP). The chemical wave produced in FP was stable, and self-propagating with a constant velocity. Results showed that the driving velocity can be well controlled by altering the initiation temperatures of FP. The swelling ratio and the size of the cargos had a key impact on the feasibility of self-driven behavior. The methodology developed here provides an effective way to convert chemical energy to mechanical work, and may be useful in energy conversion and utilization, mass transportation and other applications.
