PCM ENCAPSULATION METHOD

摘要

The invention relates to a method for the production of encapsulated PCMs, comprising the following steps: a) preparing a viscous melt by means of heating or a solution of polymers or biopolymers that form encapsulates; b) preparing a solution or suspension of PCM without mixing with the solution or melt of polymer or biopolymer from step (a) or adding the PCM to the melt or solution from step (a) (i) directly, (ii) in solution or (iii) in suspension; and c) encapsulating the PCM directly or prepared according to step (b) in the polymer or biopolymer of step (a) using any of the following techniques, namely i) electro-drawing, ii) electro-spraying, iii) blow-drawing, iv) blow-spraying, or v) micro- and nano-atomization. In a subsequent step, structures or coatings containing said PCMs are prepared for use in multiple sectors.
