Research progress in preparation and application of reversible thermochromic composite materials based on BPA
This article introduces preparation of reversible thermochromic bisphenol A(BPA)and summarizes its application,as well as preparation methods such as composite,inorganic coating,microcapsule,wet film forming,and new methods of 2,6-monosubstituted BPA composite film.It also analyzes relationship of film's crystallization phase change with dialdehydes,phenolic resins and rubber's species in 2,6-monosubstituted method.New design and research of 2,6-monosubstituted BPA's linear or aromatic phenolic resin and its composite film organic system will further promote new achievements of this type of materials in adjustable hysteresis response phase change's intelligent window,ultra-low temperature color sensitivity,color depth,stability,environmental friendliness,cynthetic resin and plastics,as well as experimental teaching.
