“…[163][164] Notably, thermal phase change materials as one of the thermoresponsive materials are now gaining more attention, requiring high form stability, high enthalpy efficiency, and outstanding thermal cycle performance. [165][166][167][168] Besides the superior mechanical properties, the advantage of slide-ring structures for the thermal phase change material is reflected in the significant increase in form stability with the cyclodextrin addition. The crystallinity of polyethylene glycol chains with cyclodextrins and the high conformational freedom of slide-ring structures achieve high phase transition enthalpy and excellent cycling performance, which will provide a convenient way for the intelligent heat treatment packaging.…”

Comprehensive SummarySlide‐ring structured polyrotaxanes with high molecular mobility and reversible conformational transition ability can achieve high performance and multifunctionality of the material in various applications. There have been many reviews describing advances in the research of rotaxanes and polyrotaxanes. However, most of them typically focus on the precise synthesis of mechanically interlocked molecules and the control of microscopic molecular shuttles. In this review, we examine the effects of motion activity and conformational transition due to molecular slide on the performance of polyrotaxanes and the latest functional applications. Different designs of polyrotaxane‐based functional materials are presented to improve the potential for applications including self‐healing stretchable elastomers/gels, stimuli‐responsive smart devices, battery electrode binders, and biomedical drug delivery. It is anticipated that this review will provide insights and guidance for future developments in the design, synthesis and application of polyrotaxane‐based functional materials.

“…Yin et al [ 45 ] used phytic acid (PA) derived from biomass as a flame retardant for PCM based on polyrotaxane (PLR). The obtained results show that the fire safety of PLR was significantly improved after modification with PA; it was possible to achieve the pHRR decrease of 54.2%, THR decrease of 34.0%, while LOI increased from 20.8% to 28.2% as it is shown in Figure 9 .…”

The accumulation of thermal energy in the form of latent heat of phase transition using phase change materials (PCMs) is one of the most attractive and studied research areas with huge application potential in both passive and active technical systems. The largest and most important group of PCMs for low-temperature applications are organic PCMs, mainly paraffins, fatty acids, fatty alcohols, and polymers. One of the major disadvantages of organic PCMs is their flammability. In many applications such as building, battery thermal management, and protective insulations, the crucial task is to reduce the fire risk of flammable PCMs. In the last decade, numerous research works have been performed to reduce the flammability of organic PCMs, without losing their thermal performance. In this review, the main groups of flame retardants, PCMs flame retardation methods as well as examples of flame-retarded PCMs and their application areas were described.
