Embodiment Construction
[0093]A detailed description of a biocomposite material 1 in accordance with aspects of the present invention shall now be described with reference to FIGS. 1 and 2.
[0094]From FIG. 1 the biocomposite material 1 can be seen to comprise a plurality of cellulose fragments 2 in the form of a network of cellulose microfibrils 3. The cellulose fragments 2 can be seen to be infiltrated with a hydrophilic (or substantially hydrophilic) binder 4 and encapsulated within a hydrophobic binder 5. In practice the cellulose fragments 2 can range from comprising a mix of individual cellulose microfibrils (typically ˜20 nm in diameter) to sections of cellulose cells typically ˜50 μm in length and breadth and less than 1 μm in thickness themselves made up of a number of cellulose microfibrils 3. A schematic representation of the chemical structure of cellulose is presented in FIG. 2.
[0095]In the present embodiment the hydrophilic binder 4 comprises partially hydrolysed polyvinyl acetate. Partially hy...
