Abstract: The invention relates to a method for producing a homogenous solution of a fluoropolymer, selected from fluoropolymers and fluoro-copolymers and mixtures of various fluoro-homopolymers and/or fluoro-copolymers in a high boiling solvent, whereby (a) the fluoropolymer to be dissolved is dissolved in a mixture of at least two solvents, the first comprising a boiling point of less than 150° C., and/or a vapor pressure of over 5 hPa (at 20° C.), and the second being a high boiling solvent comprising a boiling point at least 50 K higher than the first solvent and/or the boiling point thereof being selected so that the solvent mixture comprises a separation factor ? of ?1, and subsequently (b) the first solvent is substantially or completely removed from the mixture. The invention further relates to a method for producing suspensions of inorganic particles of a piezoelectrically and pyroelectrically active or activatable oxide in such fluoropolymer solutions and to the product of said method.

Abstract: The invention relates to a method for producing an inorganic latent heat storage material that is surrounded by an encapsulating layer that is made of an inorganic-organic polymer material that comprises a metal and/or semi-metal oxygen network with embedded organic groups. The method is characterised in that a liquid or liquefied latent heat storage material, in the form of discrete units that are to be, respectively, encapsulated, is introduced into a liquid or viscous precursor material of the encapsulating material such that the encapsulating material solidifies when coming into contact with the outer surfaces of said latent heat storage material.
