Research progress of triboelectric nanogenerator based on cellulose materials
In recent years,triboelectric nanogenerator(TENG)has developed rapidly and is widely used in the fields of energy collection,human-computer interaction,wearable electronics medical electronics and so on.Traditional TENG is usually prepared from the nonbiodegradable and unrecyclable polymer materials and metal materials,which will definitely pollute the environment.Therefore,the exploration of green TENG has become a research hotspot.Cellulose materials promote the development of environment-friendly TENG with advantages of degradability,regeneration,easy modification and processing.In this paper,the structure,working principle and working mode of TENG are briefly introduced and the research progress and application examples of nanocelluloses film,cellulose paper and cellulose aerogel as triboelectric materials are emphatically summarized.Finally,the future development of cellulose based TENG is prospected.
