Abstract
A polybutylene succinate (PBS) nanocomposite material includes a matrix comprising polybutylene succinate chains, and nanocelluloses dispersed between the polybutylene succinate chains. The PBS composite material may be produced by polymerizing 1,4-butanediol and succinic acid or a derivative thereof in a mixture of 1,4-butanediol and succinic acid or a derivative thereof with nanocelluloses. The PBS nanocomposite material and the method have improved properties, which does not require a surface hydrophobization pretreatment process of cellulose, melt kneading, and solution mixing processes.
