摘要

Synthetic polymers are the most commonly used polymers in daily life. Therefore, it is necessary to develop environmentally friendly polymers. Hydroxypropyl methylcellulose (HPMC) is a potential candidate for a biopolymer, owing to its unique properties. However, HPMC biopol-ymers have some disadvantages compared to synthetic polymers. In this study, the mechanical properties and tribological performance of MoS2 additive-enhanced cellulose matrix biocomposites were investigated in order to improve the properties of HPMC. MoS2 was incorporated into the HPMC matrix as a strengthening additive. The mechanical properties, bonding, and water vapor permeability of the composites were analyzed. The mechanical and vapor barrier properties of the HPMC films were significantly enhanced. The ultimate tensile strength and Young’s modulus of the composite films increased with the addition of up to 1 wt% MoS2. The water vapor permeability of HPMC films reduced when additives were incorporated. The wear test proves that the MoS2 additives can improve the tribological performance of the HPMC composite while reducing the friction coefficient. The main reason for enhanced tribological performance is the improvement in load capacity of the composite coating by the MoS2 additive. This MoS2/HPMC biocomposite can be used in food packaging.
