Abstract
In this work, four hydrocinnamic acid derivatives including N, N’-succinic bis(hydrocinnamic acid) dihydrazide (HASUD), N, N’-adipic bis(hydrocinnamic acid) dihydrazide (HAADD), N, N’-sebacic bis(hydrocinnamic acid) dihydrazide (HASED) and N, N’-dodecanedioic bis(hydrocinnamic acid) dihydrazide (HADOD) were synthesized via two liquid reactions. And then fourier transform infrared spectrometer and 1H nuclear magnetic resonance were used to characterize molecular structures of four hydrocinnamic acid derivatives. Additionally, the orthogonal experiment obtained the optimum synthesis process of four hydrocinnamic acid derivatives, and the maximum yield of HASUD, HAADD, HASED and HADOD were 33.3%, 43.2%, 43.5% and 51.9%, respectively. DMol3 was used to optimize geometric structure and obtain frontier orbital energy. Finally, hydrocinnamic acid derivatives and poly(L-lactide) (PLLA) were blended using the torque rheometer to investigate these role in PLLA resin. The resultant from the melt-crystallization process showed that hydrocinnamic acid derivatives as heterogeneous nucleating agents could significantly enhance PLLA’s crystallization.
