The overall objective of NANOPCM is the development, implementation, production, and demonstration of low cost and improved Phase Change Materials for new high performance insulation components in existing buildings. For this purpose, different technical innovations will be carried out during this project: 1. New low cost stable thermal storage component based on the anchorage at nanoscale of organic PCMs between the polymeric chains of selected polymers. The PCMs will be based on by-products of different industries. 2. New thermal insulation inorganic nanofoam with thermal storage capacity by the impregnation with inorganic or organic phase change materials. The nanoporous material will help to improve the thermal behaviour of the PCM and the innovative use of hydrated salts (inorganic PCM) in construction materials. 3. Improve the thermal behaviour of the materials developed with the introduction of high thermal conductive nanomaterials, CNT or CNF inside their structures. 4. Improved organic phase change microcapsules with the incorporation of high thermal conductive nanomaterials, CNT or CNF in the shell which will provide better thermal transfer to the organic paraffin inside. The objectives of this project will be achieved through 8 WP´s. WP1 is dedicated to project management, WP2-WP3 are related to the experimental development of the new materials and its characterization, WP5 to the study of the Life Cycle, the recycling possibilities and the minimization of the process cost. Finally, in WP4, WP6, WP7 and WP8 will be dealing with the validation, demonstration and dissemination of the results.
