Research Progress of Environment Friendly Plasticizers for Cellulose Acetate Processing

Abstract

Cellulose acetate (CA) is an important cellulose derivative that can undergo thermoplastic processing. Plasticizers can form stable hydrogen bonds with CA molecular chains, reducing intermolecular and intramolecular interactions, and play an important role in the melting processing of CA. In recent years, environmentally friendly plasticizers that are natural, non-toxic, odorless, low dissolution, and low migration have received increasing attention in plastic processing. This article reviews the research progress of environmentally friendly plasticizers such as natural plasticizers, ionic liquid plasticizers, citrate plasticizers, and polyethylene glycol plasticizers in the processing of cellulose acetate, and looks forward to the application prospects of environmentally friendly plasticizers.
