摘要:
以羟基多壁碳纳米管(MWCNT-OH)为导电材料,采用原位自由基溶液聚合方法制备了苯乙烯-丙烯腈共聚物(P(St-co-AN)为基体的P(St-co-AN)/MWCNT-OH导电复合材料.利用MWCNT-OH与P(St-co-AN)间的共价键相互作用组装成一种对有机溶剂具有强烈响应性能的气敏传感薄膜.用傅里叶变换红外光谱(FT-IR)及扫描电镜(SEM)对材料结构及形貌进行了表征.结果表明:MWCNT-OH与P(St-co-AN)间主要通过共价键相互作用形成紧密包覆,改善了相容性.气相性能试验表明:有机溶剂的响应行为主要受相似相容产生的膨胀模型控制.原位法构筑的传感薄膜表现出快速的响应性、良好的恢复性及重复稳定性.
Abstract:
P(St-co-AN)/MWCNT-OH conductive composite was prepared by an in situ polymerization avenue based on poly(styrene-co-acrylonitrile)(P(St-co-AN)),hydroxyl-functionalized MWCNT(MWCNT-OH).Vapor sensing films with intensive response to solvent vapors were assembled through an covalent or non-covalent interaction between MWCNT-OH and P(St-co-AN),as demonstrated by a fourier transform infrared spectroscopy(FT-IR),scanning and transmission electron microscopes(SEM).The results show that MWCNT-OH is closely coated by P(St-co-AN)through strong covalent interaction,which improves the compatibility of MWCNT-OH.Response behavior of organic solvent is mainly controlled by expansion model of similarity and compatibility; The sensing films by an in situ polymerization avenue gave an quick response,good reversibility and reproducibility.
