Abstract:

Nucleating agents play a very important role in the crystallization of polylactic acid (PLA). This paper introduced the crystallization mechanisms of PLA and the development status of biomass nucleating agents for PLA in China and overseas. These biomass nucleating agents included polysaccharide (starch, cellulose, chitin, chitosan and cyclodextrin), phenol (lignin), alcohol (inositol), protein (amino acid) and carboxylic acid (orotic acid). Furthermore, the problems in the applications of biomass nucleating agents for PLA were analyzed, and their development in the future was prospected.

Key words: polylactic acid, biomass, nucleating agent
