Abstract
Abstract Multifunctional films with integrated temperature adjustment, electromagnetic interference (EMI) shielding, and thermal camouflage are remarkably desirable for wearable products. Herein, a novel Janus‐type multifunctional ultra‐flexible film is fabricated via continuous electrospinning followed by spraying. Interestingly, in the polyvinyl alcohol (PVA)/phase change capsules (PCC) layer (P 1 ), the PCC is strung on PVA fibers to form a stable “candied haws stick” structure that obviates slipping or falling off. The film with sufficient melting enthalpy (141.4 J g −1 ) guarantees its thermoregulation capability. Simultaneously, its high mid‐IR emissivity (90.15%) endows the film with radiative cooling…
