Heat storage microcapsules providing congruent phase change, process for producing and use thereof

Heat storage microcapsules providing congruent phase change, process for producing and use thereof

The present invention relates to a core-shell heat storage microcapsule having a core containing a phase change heat storage material and a coating of amorphous glassy alginate, which coating has at least two layers and at least one layer contains nanoparticles, and the surfaces of the core and the coating are in direct or spaced contact, and the microcapsule core has a solid or internal cavity.

Additive for carbon nanotubes and polymer composites and carbon nanotubes and polymer composites

Additive for carbon nanotubes and polymer composites and carbon nanotubes and polymer composites

The present invention relates to an additive for carbon nanotube and plastic composites comprising a functionalized maleic acid anhydride-olefin copolymer, wherein the maleic acid anhydride monomer units are partially or completely converted to dicarboxylic acid ester amide and / or dicarboxylic acid half ester and / or dicarboxylic acid imide monomer units, wherein the number of maleic acid anhydride monomer units of formula (I) is from 1 to 1 to 8. The invented composite can be used, for example, for the production of heavy-duty plastics, aircraft and vehicle body components, structural materials replacing high-strength metal parts, building cladding and components, insulation materials, electrical and thermal coatings, sealants, furniture components, high-strength nets and ropes.
