Thermotropic systems with fixed domains exhibiting enhanced overheating protection performance



Within this study, a time saving photo-initiated miniemulsion polymerization process (duration of polymerization was 15 min) was established in order to encapsulate a paraffin wax with an acrylate polymer shell. The obtained freeze-dried latex was an off-white powder exhibiting spherical particles with mean diameters around 400 nm and a concentration of paraffin wax around 56%. Mixing the reaction product with a UV-curable resin matrix resulted in thermotropic overheating protection glazings with high light-shielding efficiency. © 2014 Wiley Periodicals, Inc. J. Appl.
