摘 要：Conductive polymer fibers/wires(CPFs)are important materials in modern technologies due to their unique one-dimension geometry,electrical conductivity,and ***,the advanced applications of current CPFs are limited by their low electrical conductivities(500 S/m)and poor interfacial interactions between conductive fllers(e.g.,graphite)and ***,in current electrical applications,metal wires/foils like copper and aluminum are the most frequently utilized conductive fibers/wires instead of the inferior conductive *** work successfully addresses the heavy phase segregation between polymers and conductive inorganic materials to obtain semiliquid metal polymer fibers(SLMPFs)which exhibit an ultrahigh electrical conductivity(over 10^(6)S/m),remarkable thermal processability,and considerable mechanical performance(Young s modulus:~300 MPa).Semiliquid metal(gallium-tin alloy)with tunable viscosities is the key to achieve the excellent miscibility between metals and *** the rheological results and numerical simulations demonstrate the critical viscosity matching for the successfui preparation of the *** importantly,the fibers are adapted with classic polymer melt-processing like melt injection,which indicates the scalable production of the highly conductive *** SLMPFs are highly promising substitutes for metal wires/fbers in modern electrical applications such as electricity transmission,data communication,and underwater works.
