Cellulose-Graphene Bifunctional Paper Conservation Materials: For Reinforcement and UV Aging Protection

Paper artifacts have unique cultural and historical values. However, over time, many paper appear with disease characteristics such as embrittlement photoaging, losing the most fundamental function of literature archive. The reinforcement handling degraded is, therefore, a necessary measure to extend their service life, key which lies in prevention photoaging. This intended use graphene oxide (GO) UV protective agent, carboxymethyl cellulose (CMC) reinforcement, polyethyleneimine (PEI) modifier. In this work, amino-modified composite (CMC-aGO) was prepared by chemical modification, used bifunctional protection material anti-ultraviolet reinforcement. It showed excellent performance both tensile strength testing resistance testing. CMC-aGO raw is low cost, colorless, transparent, simple synthesize, convenient operate, an conservation dual functions aging
