摘　　要：增塑的ＰＶＣ涂膜压电晶体传感器阵列用作香味传感系统曹忠，林辉概，王彬锋，王柯敏，陈泽忠，俞汝勤（湖南大学化学化工系，长沙，４１００８２）关键词阵列，压电晶体传感器，增塑的ＰＶＣ涂膜，香味传感系统吸附活性物质如类脂化合物等涂膜的压电晶体传感器（ＰＣＳ）...The traditional method for the preparation of PVC ion-sensitive membrances has been adapted to the formation of adsorptive coatings on a piezoelectric crystal sensor (PCS).Besides the PVC matrix and di-n-octylphenyl phosphate(DOOP) plasticizer, 12 adsorptive materials have been selected from 68 compounds by cluster analysis: squalane, polyethylene glycol-20M, dodecyldimethylaniline, thionalid , polyethylene glycol octylphenyl ether, suc cinimide, diacetyl cellulose, benzyltetradecylidimethylammonium chloride , 8-hydroxyquino line, N-(2-hydroxylbenzyl ) didecylamine, dimethylpropaneldiol succinate, triton X-305.The frequency shift data obtained from the sensor array responding to four commercial per fume vapours are first autoscaled and then treated by principal component aualysis. The two dimensional display of autosealed data measured by the sensor array shows well-defined clus ters for different perfume odours.The sensor array has also been applied to classification of commercial spirituous liquor,wine and soft drink samples,as well as aliphatic alcohol homo logue, and propanol isomer samples. The response characteristics of sensor arrays have been investigated experimentally.
