▎ 摘　　要

NOVELTY - Temperature sensitive composite comprises a graphene nano sheet (FGS) functionalized from poly(2-(dimethylamino)ethylmethacrylate) (PDMAEMA) (I). USE - The temperature sensitive FGS-PDMAEMA composite is useful for manufacturing a complex film (claimed). ADVANTAGE - The composite can easily controls hydrophilicity/hydrophobicity of the complex film according to the temperature change. DETAILED DESCRIPTION - Temperature sensitive composite comprises a graphene nano sheet (FGS) functionalized from poly(2-(dimethylamino)ethylmethacrylate) (PDMAEMA) of formula (I). R3 = 2,2,4,4-Tetramethyl-pentanedioic acid 2-dimethylamino-ethyl ester 2-p-tolyl-ethyl ester of formula (Ia); and m = 100-1000. INDEPENDENT CLAIMS are included for: (1) producing the composite comprising producing 2-bromo-2-methyl propanoate-3-methylphenethyl and reacting with 2-bromo butyryl bromide under the presence of base and reaction solvent and polymerizing 2-(dimethylamino)ethylmethacrylate using surface initiation atomic migration radical polymerization; and (2) manufacturing FGS-PDMAEMA complex film comprising dissolving the composite in water and deposition an aqueous suspension on a substrate. DESCRIPTION OF DRAWING(S) - The diagram shows a schematic view of a FGS-PDMAEMA composite.
