Intrinsically Flexible Polyurethane-Based Phase-Change Composites with High Heat Storage Density for Thermal Management Applications.

ABSTRACT: Phase change materials (PCMs) with high energy storage density and good flexibility are ideal for human therapy and thermal management. To overcome the common drawbacks of leakage and limited flexibility in conventional PCMs for wearable therapy, inherently flexible polyurethane-based phase change materials (PUPCMs) were first synthesized with a cross-linked network structure via a prepolymer method. To further enhance the energy storage capacity, a series of flexible phase change composites (FPCCs) with high energy storage density, outstanding flexibility, and stable shape retention were developed using a dual-encapsulation strategy. The potential of these FPCCs in personal thermal management was also systematically investigated. The 15%FPCC sample exhibited a melting temperature of 38.2
