褶皱石墨烯微球制备与浸润性调控及其丙酮感知研究
Folded graphene microsphere preparation and wettability modulation and its acetone sensing study
摘要
Abstract
For the purpose of increasing the surface roughness to obtain superhydrophobic composites,this paper introduced a binary solvent of water-acetone to investigate GO dispersion and evaporation in the binary sol-vent.Later on,by spray frying method,FGO were obtained to investigate the effect of solvent components on the wettability.Finally,FGO was compounded with PDMS to make an acetone-sensitive superhydrophobic sensor.The results show that GO is well dispersed and has a good evaporation rate in a binary solvent with a 20％water fraction,and the obtained FGO has a contact angle of 149.1°.The prepared composites have good bonding and superhydro-phobicity of 150.2°,as well as good sensing performance at acetone concentrations of 0.03～0.075 mol/L,with a sensitivity of 115(mol/L)-1.关键词
