| Abstract:Taking advantage of the strengthening mechanism of polyamide epichlorohydrin （PAE）， PAE resin reinforced polyacrylonitrile （PAN） fiber sheets were successfully prepared， PAE resin was deposited on PAN fibers to form a “self-crosslinking” networks to enhance the binding of PAN fibers. By adding low amount （0.6 %） of PAE as cross-linkers， the tensile index， tear index， and elongation of the sheet were increased by 21.0%， 25.8%， 34.4%， respectively. Analyses of attenuated totalinternal reflectance fourier transform infrared （ATR-FTIR）， X-ray photoelectron spectroscopy （XPS） and scanning electron microscope （SEM） confirmed the formation of tertiary amine group in PAE-PAN sheets by the self-crosslinking of PAE polymer. This work suggested a promising PAN fiber sheet enhancement strategy by adding PAE resin as self-crosslinking material． |
