Sorption properties of carbonized/uncarbonized cornhub powder filled natural rubber/acrylonitrile butadiene rubber biocomposite

Author(s): Iheoma C Chukwujike, Chinomso M Ewulonu, Mathew Chukwu
Abstract: The sorption characteristics of cornhub powder (carbonized/uncarbonized) filled natural rubber/acrylonitrile butadiene rubber (NR/NBR) using an aromatic solvent (toluene) have been studied. The effects of cornhub powder content, particle size, nature of solvent at temperature of 35 oC were also investigated. The restriction on elastomer swelling exerted by the cornhub on the composite was investigated. Carbonized cornhub powder of 0.1┬Ám particle size shows the lowest percentage swelling. The molecular percentage uptake of toluene for uncarbonized cornhub was higher than the carbonized cornhub. The effect of fibre loading swelling on the swelling behavior of the composite was also investigated in toluene. The percentage swelling index and swelling coefficient of the composite were found to decrease with increase in filler loadings and this shows an increased hindrance exerted by the fibre.
