This study deals with the investigation of the adsorption and thermal energy storage efficiencies of salicylidene diamino benzophenone-based highly crosslinked polymer (DABSA-HCP) as a hybrid material. Kinetic and isothermal inspection of rhodamine B (RhB) and lincomycin (LCM) showed different sorption abilities of subject molecules. While the adsorption of RhB kinetically and isothermally fitted to the Pseudo-second Order Model with the k of 0.005 and Langmuir Isotherm, respectively, LCM adsorption conformed to the Pseudo-first Order Model and Freundlich Model. Also, it was determined that the pore diffusion accompanied the adsorption, but it was not the rate-controlling step. The equilibrium was achieved in 2 h in both adsorptions. The maximum adsorption capacities were calculated as 88.50 mg/g for RhB and 37.45 mg/g for LCM. The removal efficiencies of DABSA-HCP for crystal violet and amoxicillin were determined as 61% and 27%, respectively. The highly porous DABSA-HCP was also evaluated as the supporting material thanks to its high surface area measured as 282.79 m2.g−1 for the preparation of n-eicosane (ES) based composite phase change material (PCM) for thermal energy storage. The prepared shape-stabilized composite PCM, consisting of 50%ES-50%DABSA-HCP, exhibited thermal energy storage ability with a melting enthalpy of 121.27 J.g−1 and an onset melting temperature of 35.79 °C, and was determined to have good thermal stability by thermogravimetric (TG) analysis. The fabricated functional material has the potential to be employed in the removal of other pollutants and to be used as support matrix in the design of PCM based thermal energy storage composites.
