摘要： A method for preparing a composite material that includes the steps of: (i) heat treating natural lignocellulosic fibers at a temperature of 130 to 320° C. for 2 minutes to 24 hours in an atmosphere oxygen-deficient in and in the presence of water vapor, and (ii) mixing the heat treated natural lignocellulosic fibers with at least one thermoplastic polymer in the molten state and whose melting point is less than or equal to 230° C. The method is useful for producing vehicle parts from a composite material having natural lignocellulosic fibers with reduced volatile organic compound odor emissions.

摘要： A method of manufacturing a biodegradable bioplastic includes preparing a plant derived polymer base, preparing bamboo extracts from bamboo wood, and combining the bamboo extracts with the polymer base, optionally by heating and mixing the polymer base in a liquid form together with the bamboo extracts in a liquid form. The bamboo extracts may be applied as a surface treatment of the polymer base, with the polymer base in a solid form. The plant derived polymer base may include water, potassium bicarbonate, glycerol and starch, such as arrowroot. The plant derived polymer base and the bamboo extracts may be combined at ambient temperature, heated, cooled, reheated and recooled and solidified.
