聚二甲基硅氧烷/碳纳米管导电超疏水复合涂层的制备及性能
Preparation and properties of electrically conductivesuperhydrophobic PDMS/MWCNTs coatings
摘要
Abstract
Electrically conductive superhydrophobic coatings with a certain anti-abrasion stability on glass substrates were fabricated by spraying suspension of poly(dimethylsiloxane) (PDMS) and octadecylamine functionalized multi-walled carbon nanotubes (MWCNTs).The dispersibility of MWCNTs in solution could be improved effectively by modification with octadecylamine,which improved the convenience and repeatability of spraying process and made the distribution of MWCNTs in the composite coating uniform and continuous.Scanning electron microscope,contact angle system and resistivity tester were used to characterize the properties of the coatings.The influence of the concentration of PDMS and MWCNTs on microstructure,hydrophobicity,electrical conductivity and wear resistance of the coatings were discussed.The result shows that increasing the addition of PDMS favors the enhancement of anti-abrasion stability of the coatings.However,excess amount of PDMS could cause decline of the superhydrophicity due to the decrease of roughness,and weaken the electrical conductivity due to the electrical insulation of PDMS.PDMS has good adhesiveness on various substrates,so the coating could be also applied to other substrates and has a broad application prospect.关键词
