▎ 摘　　要

NOVELTY - Method for preparing titanium dioxide/carbon nanotube/graphene/polydimethylsiloxane composite material involves adding carbon nanotubes to the surfactant dispersion and mixing to obtain suspension A; ii. adding graphite oxide and titanium dioxide to the suspension A prepared in step (i), and mixing to obtain a mixed solution B; iii. adding ascorbic acid and a foaming agent to the mixed solution B prepared in step (ii), and after mixing, post-processing to obtain titanium dioxide/carbon nanotube/graphene composite foam; and iv. adding polydimethylsiloxane main agent, curing agent and n-hexane to the titanium dioxide/carbon nanotube/graphene composite foam prepared in step (iii), and post-processing is performed. USE - Titanium dioxide/carbon nanotube/graphene/polydimethylsiloxane composite material for use in the field of photothermal actuators (claimed), solar water evaporation, oil spill environment restoration and preparing micron/nano photothermal conversion composite materials. ADVANTAGE - The method for preparing titanium dioxide/carbon nanotube/graphene/polydimethylsiloxane composite material has a micron-sized aperture and solid block shape in a macroscopic view. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for titanium dioxide/carbon nanotube/graphene/polydimethylsiloxane composite material.
