This study developed three friction models including the friction between crystalline cellulose and crystalline cellulose (FMCC), crystalline cellulose and amorphous cellulose (FMCA), and amorphous cellulose and amorphous cellulose (FMAA) to analyze the effects of loading and sliding velocity on friction and wear using molecular dynamics simulation. It is found that the friction of FMCC consists of three stages, that is the stage of static to kinetic friction (SI), S I ), the kinetic friction to stable friction (SII), S II ), and the stable friction (SIII), S III ), however, the FMCA and FMAA without the S II . The velocity affects the time to enter the S III significantly, and the loading influences the friction in the S III significantly. And amorphous cellulose is more susceptible to wear than crystalline cellulose.
