Synergistic Toughening and Strengthening of PBAT/TPS Blends by Microcrystalline Cellulose-Hyperbranched Polyester Grafting Derivative
To enhance the compatibility of the PBAT/TPS blends, a kind of microcrystalline cellulose-hyperbranched polyester grafting derivative (MCC-HBP) was synthesized to strengthen the interfacial interaction. The results indicated that when the content of MCC-HBP was 0.8 phr, the hydrogen bonding fraction of PBAT/TPS/MCC-HBP blends reached its peak at 0.41, indicating the strongest interaction between PBAT and TPS. Thermal analysis revealed that the addition of MCC-HBP shifted the crystallinity-crystallization time curve of the blend to the right, suggesting that the hydrogen bonding among MCC-HBP, PBAT, and TPS inhibited the movement of polymer chains, thereby suppressing crystal growth in PBAT. Furthermore, at 0.8 phr MCC-HBP content, the PBAT/TPS/MCC-HBP blends exhibited the widest melt processing window and the best thermal stability. The mechanical properties of PBAT/TPS blends were improved most significantly by 0.8 phr of MCC-HBP, with a 27.99% increase in tensile strength, a 23.09% increase in elongation at break, and a 40.51% increase in tensile toughness.
期刊介绍：
The Journal of Polymers and the Environment fills the need for an international forum in this diverse and rapidly expanding field. The journal serves a crucial role for the publication of information from a wide range of disciplines and is a central outlet for the publication of high-quality peer-reviewed original papers, review articles and short communications. The journal is intentionally interdisciplinary in regard to contributions and covers the following subjects - polymers, environmentally degradable polymers, and degradation pathways: biological, photochemical, oxidative and hydrolytic; new environmental materials: derived by chemical and biosynthetic routes; environmental blends and composites; developments in processing and reactive processing of environmental polymers; characterization of environmental materials: mechanical, physical, thermal, rheological, morphological, and others; recyclable polymers and plastics recycling environmental testing: in-laboratory simulations, outdoor exposures, and standardization of methodologies; environmental fate: end products and intermediates of biodegradation; microbiology and enzymology of polymer biodegradation; solid-waste management and public legislation specific to environmental polymers; and other related topics.
