基于石墨烯/聚二甲基硅氧烷复合材料的正己烷气体传感器
Graphene/Polydimethylsiloxane Nanocomposites Hexane Vapor Sensing
摘要
Abstract
This work present a chemiresistive gas sensor based on the graphene/polydimethylsiloxane(PDMS)nano-composites. The graphene/PDMS nanocomposites is fabricated by mixing liquid exfoliated graphene nanosheets with PDMS in isopropanol. The conductivity of the nanocomposites is positive related with the graphene concentration, the percolation value of which is as low as 0.41 wt%. The detection limit of the gas sensor to hexane is calculated to be 200 ppb with decent repeatability,when the graphene concentration is 0.45 wt%. The proposed gas sensor has great potential in industry applications due to its easy fabrication process,low cost and high sensitivity.关键词
