PVP-Modified PE Fiber

2× Tensile Strain

Surface modification of polyethylene fibers with polyvinylpyrrolidone significantly enhances their hydrophilicity, thereby strengthening the fiber-matrix interfacial bond and simultaneously boosting the tensile strength and ultimate tensile strain of high-strength ECC, while promoting finer and denser cracking.
