Title:
CARBON NANOTUBE MODIFIED TPU MATERIAL FOR 3D PRINTING AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/128484
Kind Code:
A1
Abstract:
A carbon nanotube modified TPU material for 3D printing and a preparation method therefor, comprising the following raw materials: a thermoplastic polyurethane elastomer, a modified carbon nanotube, a hydrolysis resistant agent, an ultraviolet absorber, a plasticizer and an antioxidant. The preparation method comprises subjecting the carbon nanotube to a surface oxidation treatment, introducing carbonyl and hydroxyl functional groups, then performing silylation treatment so as to introduce active sites, finally performing grafting modification on the surface of the carbon nanotube, and introducing amino functional groups so as to obtain a modified carbon nanotube.
