Abstract
This study presents a method for preparing biobased cellulose diacetate (CDA)/polyester blends. The method involves melt blending CDA with polybutylene adipate (PBS), polybutylene adipate/terephthalate (PBAT), or poly-L-lactic acid (PLLA) without the addition of any small molecule plasticizers, with the inclusion of 0.5 phr phosphite antioxidant Bis-(2,4-di-tert-butyl phenyl) pentaerythritol diphosphite (BPE-DP). The ratio of cellulose acetate to polyester is 8:2, 7:3, 6:4, and 5:5. CDA, PBS, and PLLA are common bio-based plastics, and PBAT can also be produced using bio-based monomers. This study leverages the high glass transition temperature (T\(_g\)) of CDA to develop CDA/polyester blends with high melt fluidity and good resistance to heat-induced deformation, after addressing the challenges of hot processing without small molecule plasticizers. This material has the potential to be applied in high-heat environments, such as car engine, and can be fully bio-based.
期刊介绍：
Cellulose is an international journal devoted to the dissemination of research and scientific and technological progress in the field of cellulose and related naturally occurring polymers. The journal is concerned with the pure and applied science of cellulose and related materials, and also with the development of relevant new technologies. This includes the chemistry, biochemistry, physics and materials science of cellulose and its sources, including wood and other biomass resources, and their derivatives. Coverage extends to the conversion of these polymers and resources into manufactured goods, such as pulp, paper, textiles, and manufactured as well natural fibers, and to the chemistry of materials used in their processing. Cellulose publishes review articles, research papers, and technical notes.
