Abstract In this paper, a safe, non-toxic, and low-cost method was adopted to modify ultra-high molecular weight polyethylene (UHMWPE) fibers. gallic acid (GA) polyethyleneimine (PEI) were co-deposited on the surface of UHMWPE fibers by Michael addition Schiff base reaction in an alkaline solution with pH 8.5. The structure properties analyzed characterized Fourier Transform Infrared Spectroscopy (FTIR), X-ray Photoelectron (XPS), Thermogravimetric Analyzer (TG), etc. morphology degree firmness coatings observed Scanning Electron Microscope (SEM), effects different mass ratios GA-PEI investigated. results showed that active functional groups modified increased, bending interfacial shear strength composites epoxy resin significantly improved, increased 33.1 % 45.9 %, respectively.
