| description | Green nanocomposites containing bacterial cellulose and kaolin had been
fabricated through a series of benign procedure utilising sodium hydroxide
solution to purify the bacterial cellulose and distilled water as medium of mixing
to obtain slurry of BC/K nanocomposites that were further moulded into
becoming sheets. Increasing the amount of the bacterial cellulose improved the
mechanical properties of the nanocomposites including modulus of elasticity,
strength, strain, and toughness due to the solid ultrafine network fibres stabilised
with hydrogen bonds. The nanocomposites possess a nanoporous structure
supported by their hydrophilic property which is an ideal criteria for providing an
optimal wound healing environment including, but not limited to, having an
ability to maintain a moist environment for accelerating the healing process. The
moisture levels concurrently plasticise the composites more effectively and thus
the materials would be able to stretch and deform to a greater extremity before
failing. Investigation on the performance of the nanocomposite for blood clotting
potential was carried out using blood of mice. Increasing the amount of the kaolin
shortened the blood clotting time. Higher kaolin content composites were found to
have a higher percentage of smaller pores which allowed more of the blood to
come into contact with kaolin particles and hence blood clotting occurred faster. |
