    摘要： A preparation process for preparing an environment-friendly cellulosic film is provided to prepare a cellulosic film from wood pulp by using an environment-friendly construction method, and to reduce expenditure for medicine by not using NaOH or H2SO4 by omitting an alkali cellulose manufacturing process and a xanthation process. A preparation process for preparing an environment-friendly cellulosic film comprises the steps of: manufacturing a dope containing pulp 5~15 weight% with alpha-cellulose content of 90% or more and N-methylmorpholine-N-oxide solution 85~95 weight%; extruding the dope from a die onto a moving support body; casting the extruded product to form sheet-like materials; washing the cast N-methylmorpholine-N-oxide from a sheet; and drying the washed sheet.

    摘要： A biocomposite material (1) and methods of production thereof are described. The biocomposite material (1) exhibits a physical stiffness, strength and toughness comparable to known glass fibre composites while its composition makes it inherently impermeable to water. A general formulation for the biocomposite material (1) is given by the expression: Cel(1-x-y) HPIx HPOy where "Cel" represents cellulose fragments (2), "HPI" represents hydrophilic binders (4), "HPO" represents hydrophobic binders (5) and (x) and (y) quantify the percentage by weight of the hydrophilic (4) and hydrophobic binders (5) present within a material, respectively. The described properties of the biocomposite material (1) are achieved when (x) is within the range of from 0.05 to 0.55 and (y) is within the range of from 0.05 to 0.65.
