【摘要】：通過流變學(xué)的方法研究了十六烷基三甲基水楊酸銨(C_(16)TASal)與偶氮苯(AZB)構(gòu)筑的光響應(yīng)流體的流變特性.結(jié)果表明,在一般條件下,由于擬網(wǎng)絡(luò)結(jié)構(gòu)的形成,C_(16)TASal體系形成高黏彈性的膠束溶液.當(dāng)體系中加入偶氮苯后,溶液的黏度大大降低.由于偶氮苯的順-反光異構(gòu)化性能,在紫外-可見光照射下,C_(16)TASal/AZB混合體系的黏彈性能被可逆地調(diào)控.與十六烷基三甲基溴化銨(CTAB)/NaSal/AZB混合體系的對比實(shí)驗(yàn)發(fā)現(xiàn),后者在紫外光照射下所有溶液黏度均降低,當(dāng)用可見光照射時,體系的黏度未發(fā)現(xiàn)可逆性能.用紫外、紅外、核磁共振光譜以及透射電子顯微鏡等技術(shù)輔助研究混合體系的光敏特性及微觀結(jié)構(gòu).
[Abstract]:The rheological properties of photoresponsive fluids constructed by cetyltrimethyl ammonium salicylate (C16) TASal) and azobenzene (AZB) were studied by rheological method. The results show that C _ (16) TASal system forms highly viscoelastic micelle solution under general conditions due to the formation of quasi-network structure. When azobenzene was added to the system, the viscosity of the solution decreased greatly. Because of the cis-reflective isomerization of azobenzene, the viscoelastic properties of C16 TASal/AZB mixed system are reversibly regulated under UV-visible light irradiation. Compared with the mixed system of cetyltrimethylammonium bromide (CTAB) and NaSal/AZB, the viscosity of the latter solution decreased under UV irradiation, and no reversibility energy was found when the solution was irradiated by visible light. The characteristics and microstructure of Guang Min were studied by UV, IR, NMR and TEM.
