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: A thermoplastic composition includes: (a) a thermoplastic polymer component including a crystalline or semi-crystalline polymer: (b) carbon fiber: (c) from about 0.01 wt % to about 10 wt % of at least one nucleating agent including a non-electrically conducting filler, an organic nucleation agent, or a combination thereof; and (d) from 0 wt % to 30 wt % of an amorphous polymer. The carbon fiber has a nominal fiber diameter of from about 3 micron (μm) to about 13 μm. The composition has a surface resistivity that is at least 50% lower than that of a substantially identical reference composition that does not include the at least one nucleating agent. The combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the thermoplastic composition.

Abstract: Polymer compositions are provided, and articles made therefrom. The polymer compositions comprise from 25 to 50 wt. % of a thermoplastic polymer; from 10 to 45 wt. % of a thermally conductive filler; from 15 to 30 wt. % of a carbon fiber; from 2 to 8 wt. % of a toughener; and less than 5 wt. % additives. The polymer composition is substantially free of glass fibers. The polymer compositions described herein surprisingly exhibit significantly improved thermal conductivity relative to analogous polymer compositions not comprising the toughener and/or in which the carbon fiber is replaced by glass fiber.
