Tea Fiber/PHBV/PBAT Ternary Composite and Preparation Method and Application Thereof
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.
Polyvinyl acetal and cellulose ester multilayer interlayers
A multilayer interlayer structure having a first and second polyvinyl acetal (poly(vinyl acetal)) layer and a cellulose ester layer having a thickness of at least 10 mils disposed between the first and second poly(vinyl acetal) layers. The cellulose ester layer can have a higher storage modulus and/or higher Tg than at least one of the poly(vinyl acetal) layers. The interlayer structure is useful to make glass panels having high stiffness and which possess good optical clarity for a variety of applications, including outdoor structural applications.
