Description

The feasibility of making polymer crosslinked materials with applications in improving energy efficiency is here demonstrated. The encapsulation of phase change materials (PCM), for thermal energy storage/release, and sulphur inverse-vulcanization (producing materials with useful electrochemical properties) are here used as case studies. Effective thermal properties of the produced encapsulated PCM materials were measured through TG/DSC analysis (see graphical abstract). Designing tools allowing the synthesis of materials with tailored thermal properties were exploited (e.g. use of controlled radical polymerization). Sulphur-rich networks are synthetized using different operation conditions (e.g. considering RAFT/NMRP). Testing of these materials in Li-S batteries to assess the impact of the synthesis conditions in their electrochemical properties is ongoing work.
