Phase change fibers (PCFs) are increasingly popular in thermal storage and release applications, such as temperature management. However, a simple but effective integration of conductive materials into PCFs to deliver ultrafast conduction remains big challenge. Herein, facile one-pot coaxial wet spinning strategy based on sheath-confinement-induced orientation arrangement hydroxylated boron nitride nanosheets (BNNs-OH) is proposed fabricate the high-performance PCFs. For core-sheath PCFs, cellulose nanofiber (CNF)-reinforced paraffin (CNF/PW) emulsions serve phase core, while dissolved well-dispersed BNNs-OH act sheath precursor. By increasing extrusion speed liquid contraction fiber gradually finalized induce alignment confinement effect. Consequently, highly oriented (f = 0.8) endow with high transition enthalpy (125.1 J g-1), excellent conductivity (10.15 W m-1K-1), rapid heat transfer rate (1.6 cm s-1); moreover, as-prepared show good tensile strength (11.21 MPa) leakage-proof (0.13%).
