Abstract:Recent years， due to it combined properties of nanocellulose （excellent mechanical properties， optical properties， high specific surface area， low coefficient of thermal expansion and environmental friendliness） and copper （electrical conductivity， thermal conductivity， antibacterial properties）， the nanocellulose/copper nanoparticle composite materials had a wide range of applications in the fields of lithium-ion batteries， heterogeneous catalysis and antibacterial. The preparation methods and physicochemical properties of nanocellulose and copper nanoparticle were introduced， respectively. It focused on the preparation methods （physical deposition and chemical reduction method）， physicochemical properties （electrical conductivity， catalytic performance and antibacterial properties） of nanocellulose/copper nanoparticle composite materials and the application progress in the fields of electronic devices， catalysts and antibacterial materials. Finally， the problems of nanocellulose/copper nanoparticle composite materials were summarized and the future development trend was looked forward in this paper.
