Abstract:
A method of manufacturing a biodegradable polymeric composite material comprising:drying bacterial cellulose having ribbon-shaped micro-fibrils to produce a bacterial cellulose powder; macerating the bacterial cellulose before of after producing the bacterial cellulose powder; dehydrating the bacterial cellulose after maceration; and mixing the bacterial cellulose powder with a biodegradable polymeric material selected from the group consisting essentially of polyhydroxybutyrate/valerate, poly-&bgr;-hydroxybutyrate, polycaprolactone, polybutylenesuccinate, polybutylenesuccinate/adipate, polyethylenesuccinate, polylactic acid, starch/synthetic biodegradable plastic, cellulose acetate, chitosan/cellulose and denatured starch, to produce a biodegradable polymeric composite material.
