▎ 摘　　要

NOVELTY - Maleated polymer-graphene oxide composite elastomer comprises non-reduced graphene oxide (GO) fillers; and maleated polymers covalently bound to the graphene oxide fillers via maleic acid covalent bonds. USE - The maleated polymer-graphene oxide composite elastomer is useful in gas separation membrane, gas separation system, gas barrier membrane, hydrophobic coating, asphalt additive, shingle additive, and wearable device (all claimed). It can also be used as a desalination membrane, or used in flexible displays and devices for monitoring physiological signals. ADVANTAGE - The maleated polymer-graphene oxide composite elastomer may exhibit less or no decreased elasticity as its mechanical strengths are increased. It is elastic, facilitating wear-ability, and hydrophobic, thus repelling water. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) forming a maleated polymer-graphene oxide composite elastomer, which involves reacting maleic anhydride groups on maleated polymers with oxidative groups on GO fillers to form covalent bonds and to crosslink the maleated polymers via the GO fillers; (2) a gas separation membrane comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; (3) a gas separation system comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; (4) a gas barrier membrane comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; (5) a hydrophobic coating comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; (6) an asphalt additive comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; (7) a shingle additive comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above; and (8) a wearable device comprising the maleated polymer-graphene oxide composite elastomer or a maleated polymer-graphene oxide composite elastomer formed using the method above.
