Gamma radiation-assisted functionalization of flax fibers for diversified applications

In this study the flax fiber surface, which has gained immense attention, is modified by grafting methacrylamide using gamma radiation. The monomer and inhibitor concentrations, irradiation dose and dose rate have been optimized to obtain the desired grafting yield (55 wt%). The Fourier transform in...

Description
Summary:In this study the flax fiber surface, which has gained immense attention, is modified by grafting methacrylamide using gamma radiation. The monomer and inhibitor concentrations, irradiation dose and dose rate have been optimized to obtain the desired grafting yield (55 wt%). The Fourier transform infrared spectroscopy confirms the attachment of methacrylamide onto flax fiber. The impact of grafting on useful properties of fiber is further investigated. The mechanical properties are found to be well-maintained. The thermal stability of the modified flax fiber is improved by 50 °C. No post-grafting damage to the fiber is observed from scanning electron microscopic study.
