Effect of ecofriendly coating and treatment on mechanical, thermal and morphological properties of sisal fibre
2019
The objective of the present work is to overcome the limitations of sisal fibre and to improve its performance byecofriendly treatment (sodium bicarbonate) and ecofriendly coating [poly lactic acid (PLA)]. Mechanical, thermal, andmorphological analyses of untreated, treated and treated + coated sisal fibres have been carried out and compared. Sisalfibres are treated with varying concentrations of sodium bicarbonate (5, 10, 15 and 20 % w/v) at varying soaking timeperiods (24, 48, 72, 96 and 120 h). PLA coating on sisal fibres is performed at a varying PLA concentrations (2, 4, 6 and 8%w/v). Scanning electron microscope and X-ray diffraction have been used for the examination of morphological andcrystalline analysis respectively of untreated, treated and treated + coated sisal fibres. It is observed that the combined effectof treatment and coating leads to improvement in crystallinity, water absorption resistance, and mechanical and thermalproperties of sisal fibres.
