摘要：Polylactic acid (PLA) is currently the largest volume of production and application of synthetic biodegradable polymer via bio-derived materials. However, the relaxation characteristics and very low crystallization rate determined by the hand- structure of PLA chains result in low heat-resistance temperature and troublesome demold behavior for fast extrusion and/ or injection molding process. It is well known, by introducing of nucleating agent and crystal growing accelerator, the crystallization properties of PLA materials can be improved efficiently. In the paper, the isothermal crystallization behaviors of PLA, which include the rate and temperature of crystallization, crystallinity, crystals morphologies, were systemically shown. Meanwhile, a serious of regulation strategies of isothermal crystallization kinetics of PLA materials, such as adding of biodegradable polymers, different dimension of fillers, various chain-reconstruct for PLA, processing flow fields and post-treatment, were comprehensively summarized. Additionally, the regularity strategies and next study points for PLA isothermal crystallization behavior were also presented.
