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) HPI x HPO y 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.

摘要:
The present invention relates to nanoparticles and their use to form nanocomposite material, in particular bionanocomposite material, specifically wherein the nanoparticles are formed using plant virus attached to a scaffold of cellulosic material and / or cellulose derived materials, in particular wherein said cellulosic material further comprises plant cell components, for example hemicellulose, pectin, protein or combinations thereof.
摘要:
A composition and method of preparing a composition is presented wherein the composition comprises cellulose platelets and the cellulose platelets comprise at least 60% cellulose by dry weight,less than 10% pectin by dry weight and at least 5% hemicellulose by dry weight. The composition can be concentrated to at least 25% by weight solids content by pressing under low pressure, whilst retaining the ability to be re suspended within an aqueous medium. The resulting aqueous medium obtains the desired properties of the composition, such as increased viscosity or increased dispersion of pigment particles, for example, to the same extent as the composition before pressing.

摘要:
A method for replacing eggs and/or egg materials, particularly egg yolks, and/or for replacing a significant proportion of its fat and/or sugar content in a food composition, the method comprising the step of providing, in the food product, cellulose-containing particles that are derived from a herbaceous plant and that comprise: less than 30 wt% extractable glucose; and extractable xylose in an amount of at least 3 % of the amount of extractable xylose in the plant. The replacement method involves providing, in the composition, cellulose-containing particles made from a herbaceous plant material by a process of: i) comminuting the plant material to form particles of the plant having a mean major dimension of less than 10 mm, preferably less than 100 µm, ii) then treating the plant particles from i) with a peroxide and water, iii) then heating the peroxide-treated plant particles from ii), and iv) then isolating the cellulose-containing particles.
摘要:
A fibre reinforced material (1) and methods of production thereof are described. The fibre reinforced material (1) comprises a matrix material made from a biocomposite material (3) produced through the extraction of cellulose from plants. Within the biocomposite material (3) are located a plurality of fibres (2). The described material (1) exhibits a physical stiffness, strength and toughness that is greater that that for known carbon fibre reinforced plastics. Furthermore the composition of the material (1) also makes it inherently impermeable to water. This makes the fibre reinforced material (1) ideally suited for making monolithic.structures, laminate structures (12) and rod structures for use in a variety of fields, for example as fishing rods.
