Tetrahydrofuran is a heterocyclic organic compound with the molecular formula C4H8O. THF belongs to the group of ethers and is a fully hydrogenated product of furan, a colorless, water miscible organic liquid with a low viscosity at room temperature and pressure. The chemical formula of this cyclic ether can be written as (CH2)4O. Due to its long liquid range, THF is a commonly used medium-polar nonprotonic solvent. Its main use is as a precursor for polymers. Although the odor and chemical properties of tetrahydrofuran are very similar to those of ether, its anesthetic effect is very poor.
Poly Butylene Adipate-Co-Terephthalate is a thermoplastic biodegradable plastic, which is a copolymer of butylene adipate and butylene terephthalate. PBAT has the characteristics of both PBA and PBT, with good ductility and elongation at break, as well as good heat resistance and impact performance; in addition, PBAT also has excellent biodegradability, and is one of the most popular and best degradable materials in biodegradable plastic research and market application.
Poly butylene adipate-co-terephthalate (PBAT) is a biodegradable polymer synthesized from petrochemical resources. PBAT has a very high elongation at break, which makes PBAT one of the most promising alternatives to LDPE packaging films. However, the applicability of PBAT films is still limited by low strength. In this work, we used polyethylene glycol 600 (PEG-600) as a coating agent to modify the surface of calcium carbonate. A series of PBAT/CaCO3 composite films with different CaCO3 particle sizes. The effects of particle size and capping agent content of CaCO3 filler on the mechanical.
