Natural fiber thermoplastic composites: exploring the impact of plasma surface treatment on viscoelastic and thermal behavior

Popis výsledku v původním jazyce

The demand for bio-fiber composites has witnessed a remarkable rise in recent years. The present work is focused on development of a novel sustainable composite made of plasma-treated polyethylene (PPE) and banana fiber (BN) an agro-residue, fabricated using compression molding process. The viscoelastic and thermal properties of the composites were examined using rheological and thermomechanical analysis (TMA), and the treatment’s efficiency was determined by comparing it to the properties of composites made with untreated polyethylene (PE). BN was added to the composites in varying amounts, ranging from 10 % to 40 %. The viscoelastic characteristics of the composites were assessed through rheological analysis using both strain sweep and amplitude sweep techniques. The increment in storage modulus for amplitude sweep mode of analysis indicates that the plasma treatment enhanced the interfacial interaction between the fiber and polymer. Morphological properties of the composites were examined using scanning electron microscopy(SEM), which clearly showed improvement in fiber-matrix interfacial bonding for treated composites. Furthermore, functional group identification of the composites was performed using FTIR, which gave further evidence for the efficiency of plasma treatment by revealing the formation of new polar functional groups on the surface of treated composites. The thermal characteristics of the composites were determined via TMA and DSC analysis. Plasma-treated composites showed reduced thermal expansion than untreated composites according to the coefficient of thermal expansion (CTE) study, indicating that PPE composites had superior dimensional stability due to enhanced fiber-matrix bonding. Hence PPE natural fiber composites could be used for various industrial applications (especially for thermally sensitive) as these composites will not reduce their structural stability much during the fabrication.n
