Despite great success in design and preparation of phase change microcapsules, the balance anti-leakage, high thermal conductivity, multi-source energy exploitation are still difficult to be achieved simultaneously, which remains long-standing bottleneck for efficient safe harvesting. In this work, a multifunctional double-shell PANI microcapsule (MC) encapsulating material (PCM) was designed fabricated via an emulsion photopolymerization strategy. Thanks outstanding anti-permeability, photo-thermal property PANI, as-prepared achieves three synergetic effects simultaneously: low leakage rate, solar exploitation. The encapsulated PCM has almost unchanged Tm Tc, negligible (≤0.2 wt%) normalized melting solidified enthalpies after 100 heating/cooling cycles. presence polyaniline shell improves conductivity efficiency providing promising strategy extend single source energy. addition heat storage, microcapsules also possess anticorrosion property, is particularly attractive coating applications. Accordingly, resulted could act as candidate with all-in-one features temperature regulated properties, durability anti-corrosion would stimulate wide application energy-saving anticorrosive smart coatings.

The development of advanced composite solid-solid phase change materials (SSPCMs) is urgent to explore for improving solar energy harvesting and storage. Herein, novel SSPCMs with synergetic cross-linking structure were fabricated through polymerization using GO TiO2 constructed on the polyurethane framework skeleton. enhanced polymer played a role as skeletal encapsulate PEG in molecular chains, provided highly thermal conductive pathways SSPCMs. nanoparticles performed extended surface further improvement conductivity. exhibited remarkably improved conductivity high 0.7 W/(m‧K) fast response rate. good light adsorption property absorbance efficiency by 94.4%. And photo-thermal conversion reached 93.5%. Meanwhile, excellent anti-leakage performance shape stability under temperature. Consequently, as-prepared possessed potential applications storage utilization systems.
