Abstract: The invention provides a tea fiber/PHBV/PBAT ternary composite and its preparation method and application. Comprising the components in parts by weight, the composite contains 30-80 parts of a blending polymer of poly(butyleneadipate-co-terephthalate) (PBAT) and poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), 20-70 parts of tea powder, 1-19 parts of a plasticizer, 0.6-6 parts of an interface modifier, 3.3-10 parts of an auxiliary packing and 0.7-2 parts of a nucleating agent. The composite is environmental-friendly and cost-effective, exhibiting excellent mechanical properties such as hardness, compressive strength, and ductility. It can be used to manufacture environmental-friendly cups, tableware, compost bags, trash bags, shopping bags, electronic packaging bags, mulch films, 3D printing materials, foaming materials, and other plastic products.

Abstract: The present invention relates a biodegradable 3D composite hydrogel scaffold and a process for preparing the same from a cross-linkable synthetic biodegradable polymer, methacrylated poly multi-carboxylic acid-polyethylene glycol (MA-PMCA-PEG) and a modified natural polymer maleated gelatin (GEL-MEA). The invention deals with development of cross-linkable synthetic and natural polymers through simple and cost-effective methods. A multicarboxylic acid-b-polyethylene glycol (PMCA-PEG), is synthesized by a direct melt polycondensation technique and thereafter methacrylated using glycidyl methacrylate to prepare cross-linkable MA-PMCA-PEG, which is a new biodegradable material with excellent cross-linking properties. The natural polymer gelatin (GEL) is reacted with maleic anhydride (MEA) to get cross-linkable GEL-MEA.
