Tween 20/Span 20和纤维素酶协同分散酞菁铜颜料
Synergistic dispersion of copper phthalocyanine pigment with Tween 20/Span 20 and cellulase
摘要
Abstract
The copper phthalocyanine pigment (CuPc) was dispersed by nonionic surfactants Tween 20/Span 20. By the tests of wettability and dispersity, the optimal mass ratio of Tween 20 and Span 20 was 7:3, and the HLB value was 14.27. Subsequently, cellulase was added into the surfactant solution. The pigment dis-persion test showed that Tween 20/Span 20 and cellulase produced synergistic enhancement effect, and the best mass ratio of Tween 20/Span 20 was 8:2. The surface modification of CuPc by Tween 20/Span 20 and cellulase was confirmed by infrared and thermogravimetric analysis. The interaction between Tween 20/Span 20 and cellulase was analyzed by conductivity,UV and fluorescence spectrum,respectively.关键词
