Research Progress on Thermoplastic Cellulose Materials

Natural cellulose cannot be melted and is difficult to process due to its strong hydrogen bonding network. Thermoplastic processing of cellulose is achieved only under harsh processing conditions or with the addition of large amounts of plasticizers, but the resulting material suffers from numerous drawbacks. So the internal plasticization method of introducing new derivatized groups has received extensive attention, but the internal plasticization method will lead to a significant decrease in the degradation performance of cellulose materials. How to prepare cellulosic materials with both thermoplasticity and degradability remains a challenge. This paper summarizes the relevant progress in the field of thermoplastic processing of cellulose materials, promoting the construction of materials with both thermoplasticity and degradability to solve the environmental hazards of thin and light materials such as heat-sealing coatings and films.
