The preparation and properties of microcapsule containing 2,5-diphenylethynylthiophene with two methods

Microcapsules containing 2,5-Diphenylethynylthiophene were prepared by two methods of interfacial polymerization and in situ polymerization,in order to solve the problem of invalid photodegradation and study the influence on morphologies and diameter of microcapsules of the two different methods.Infrared spectrum of microcapsules were also studied.The results showed that the results showed that the wall materials mass of melamine and formaldehyde were fixed and reacted in a certain pH in the in situ polymerization.In the interfacial polymerization,as wall materials,the dosage of isophorone diisocyanate tripolymer and diethylenetriamine,including reacting pH,were not strict.From the preparation and results of two methods,it was showed that interfacial polymerization was a convenient,rapid and effective method for preparing microcapsule.
