摘要: Poly (vinyl alcohol) (PVA) fibers were strengthened using multiwalled carbon nanotubes (MWCNTs) functionalized a green modifier tea polyphenols (TP). MWCNTs first modified TP to increase their dispersity in dimethyl sulfoxide (DMSO)/water solution, and then PVA was added the dispersion form new of PVA/MWCNTs/TP/DMSO/water. The homogeneous extruded through spinning hole into cold methanol continuous gel-spinning process followed by hot-drawing. tensile strength well-oriented PVA/MWCNTs composite containing merely 0.6 wt% surprisingly more than 2.6 times that pure fiber. Structure characterization showed well-dispersed caused interfacial interactions between matrix bridge effect TP.
