Title:
POLYLACTIC ACID-LIGNIN COMPOSITE MATERIAL FOR 3D PRINTING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/186601
Kind Code:
A1
Abstract:
The present invention relates to a polylactic acid-lignin composite material for 3D printing. The present invention also relates to a preparation method for a polylactic acid-lignin composite material for 3D printing. In the present invention, poly(2-ethylhexyl acrylate) (EHA) was grafted onto the surface of lignin through copolymerization. Poly(2-ethylhexyl acrylate) (EHA) has the same ester groups as in polylactic acid (PLA), and thus has favorable compatibility with polylactic acid.
