1.Novel controlled releasing polythiourea microcapsules were prepared from terephthaloyl diisothiocyanate and o-phenylenediamine by interfacial polycondensation.
3.Microcapsules adventatial can be used by hydrophilic polymers for material, such as glutin, pectoylic, agaragar, aclylate cellulytic and methacrolein.
3.Each sheet contains millions of microcapsules, about as wide as a human hair, filled with negatively-charged white pigments and positively-charged black pigments.
4.Well, you could also put heat-sensitive dyes inside of microcapsules and you could make different tattoo inks that change color at different temperatures.
