Poylsaccharide rubber composites - preparation and properties

Polysaccharides like nanofilibrated cellulose (NFC) or engineered polysaccharide systems modified by enzymatic reactions are renewable materials with a high potential as active fillers for elastomers. Advantages are low density for saving weight and high strength in combination with high specific surfaces. NFC-characterized polysacharide basing fillers are used for their specific surface, particle size and chemical structure. The problem of incorporating polar polysaccharide basing fillers, containing more or less water as raw material, into the rubber matrix can be solved using latex compounding, pretreatment of the fillers and optimized coagulation strategy. The resulting nanocomposites are characterized by properties.
