Abstract

See full text

Unique, inexpensive, and strong biocomposites are obtained from blending cellulose matrix materials with lignocellulosic reinforcement materials with the aid of alkaline aqueous solvent and cold temperatures. These lignocellulosic composites (LCs) are produced without use of any thermoplastic resins, adhesives, catalysts, plasticizers or complicated chemical or physical procedures. The LCs include a matrix and a reinforcement material. The matrix is a cellulose material (e.g., cotton, hemp, flax, or wood) that is liquefied using an aqueous alkaline solvent solution under cold temperatures to more readily adhere and/or incorporate/encapsulate the lignocellulosic reinforcements (wood chips, fibers, and other lignocellulosic sources).
