▎ 摘  要

NOVELTY - Graphite oxide-polyester elastomer composite material comprises (in wt.%): polyester segment (40-73), polyether (25-55), graphene oxide segment (0.6-2.5), catalyst (0.1-2) and stabilizing agent (0.1-1.8), where polyester segment comprises aromatic dicarboxylic acid or ester and aliphatic diol, and polyether segment comprises aromatic dicarboxylic acid or ester and polyether diol. USE - Graphite oxide-polyester elastomer composite material. ADVANTAGE - The graphite oxide-polyester elastomer composite material has good mechanical property, good conductivity and antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing graphite oxide-polyester elastomer composite material, which involves: (A) pre-treating graphene oxide by adding graphene oxide into water and then dispersing ultrasonically for 20-50 minutes; (B) adding aliphatic diol to the dispersed material and then stirring the obtained material at 155-180 degrees C; (C) distilling the stirred material to remove water and to obtain graphene oxide-aliphatic diol solution; (D) adding aliphatic and aromatic dicarboxylic acid or ester, polyether diol to the grapheme oxide-diol solution and then adding the obtained material to reaction vessel; (E) stirring the obtained material at 180-200 degrees C to perform ester exchange reaction and then adding the obtained material with more than 90% stabilizing agent; (F) heating the obtained material to 230-260 degrees C under regulating vacuum degree of 100-200 Pascal for 4-6 hours to perform condensation polymerization and to obtain desired viscous material; and (G) filling nitrogen to the reaction vessel and discharging and cutting the obtained material to obtain graphite oxide-polyester elastomer composite material.
