Cellulose derivative as protection coating: Effect of nanoparticle additives on load capacity

The cellulose derivative hydroxypropyl methylcellulose (HPMC) has recently been extensively studied and used in mechanical applications. However, the softness susceptibility to deformation of HPMC limited its further In this study, metal nanoparticles (nano-aluminum nano-copper) nano-metal oxide particles (nano-alumina nano-copper oxide) were as additives form a composite film with improved properties, particularly load capacity. addition high levels provided higher Among nano-additives Cu (2 wt.%) highest capacity, improving capacity pure by 250%. surface treatment strengthening is an important step. Adding specific high-strength high-modulus soft matrix can effectively improve load-bearing material. This study proposes simple evaluation method for capability coating well.
