Abstract
The proposed project "Microencapsulation of phase change materials" is aimed at studying the microencapsulation process of Phase Change Materials (PCMs) from the group of higher hydrocarbons by in situ polymerisation of aminoaldehyde prepolymers in oil-in-water emulsion systems. The research will particularly focuss on (1) studies of polycondensation process of different modified melamine-aldehyde prepolymers and styrene-maleinanhydride modifiers, and their effects on microcapsule wall hardening, residual monomers content, as well as on thermal, mechanical and permeability properties of microcapsule walls, (2) studies of methods of removing residual formaldehyde from microcapsule suspensions after the polymerisation has been terminated, (3) development and testing of microencapsulated PCMs on non-woven textile carriers, including the studies of types and quantities of binders, quantities of microencapsulated PCMs, methods and techniques of coating, impregnating and drying, (4) development/adaptation of analytical methods for the determination of low concentrations of residual formaldehyde in microcapsule suspensions, dry microcapsules, and end products, as well as methods for determination of thermal effectivity of microencapsulated PCMs on textile carriers.
