摘要

为了克服外部环境对光致变色化合物性能的影响，拓展其应用领域，人们制备了各种光致变色微胶囊。然而，壁材对光致变色化合物性能的影响还有待进一步研究。本研究以聚氨酯/壳聚糖为壁材，二元乙烯分子为芯材，制备了两种光致变色微胶囊。研究了微胶囊的光致变色性、抗疲劳性、密封性和热稳定性等性能，并探讨了壁材对二元乙烯光致变色性能的影响。此外，制备的微胶囊已成功应用于光致变色智能纺织品的棉织物上。

Preparation of photochromic microcapsules with a diarylethene and polyurethane/chitosan for smart textiles

In order to overcome the influences of external environment on the properties photochromic compounds and expend their applications fields, various photochromic microcapsules have been prepared. However, the effects of wall materials on the properties of photochromic compounds need to be further studied. In this study, two photochromic microcapsules were prepared with polyurethane/chitosan as wall materials and a diarylethene molecular as core material. The properties such as photochromism, fatigue resistance, the sealing, and thermal stability of the microcapsules were studied, and the effects of the wall materials on the photochromic properties of the diarylethene were also investigated. Furthermore, the prepared microcapsules have been successfully applied to cotton fabrics of photochromic smart textiles.

期刊介绍： Dyes and Pigments covers the scientific and technical aspects of the chemistry and physics of dyes, pigments and their intermediates. Emphasis is placed on the properties of the colouring matters themselves rather than on their applications or the system in which they may be applied. Thus the journal accepts research and review papers on the synthesis of dyes, pigments and intermediates, their physical or chemical properties, e.g. spectroscopic, surface, solution or solid state characteristics, the physical aspects of their preparation, e.g. precipitation, nucleation and growth, crystal formation, liquid crystalline characteristics, their photochemical, ecological or biological properties and the relationship between colour and chemical constitution. However, papers are considered which deal with the more fundamental aspects of colourant application and of the interactions of colourants with substrates or media. The journal will interest a wide variety of workers in a range of disciplines whose work involves dyes, pigments and their intermediates, and provides a platform for investigators with common interests but diverse fields of activity such as cosmetics, reprographics, dye and pigment synthesis, medical research, polymers, etc.
