Improved properties of corn fiber-reinforced polylactide composites by incorporating silica nanoparticles at interfaces

Abstract

In this work, we report a novel strategy for improving the interfacial nature in corn fiber/polylactide (CRF/PLA) composites by directly applying a sizing containing silica nanoparticles on the surface of CRFs. This results in enhanced mechanical properties of the CRF/PLA composites. These improvements can be mainly attributed to the presence of silica nanoparticles on CRF-PLA interfaces, which act to resist the crack propagation. The increased surface roughness of CRFs from incorporated silica nanoparticles may also contribute to the enhanced mechanical properties. This simple methodology can be easily scaled up and thus shows great promise in industrial applications.

Mechanical Properties of Polylactide Matrix Composite Reinforced with Long Maize Stalk Fibers

“…Reduction in strain of fi ber samples is due to poor interfacial adhesion between PLA and fi ber [31]. The improvement of interfacial adhesion can be obtained by modifying the fi ber surface [27,28,32]. The CS can aff ect the interphase formation and mobility of polymers molecules in the composite.…”

Plant fiber‐reinforced composites based on injection molding process: Manufacturing, service life, and remanufacturing

“…Grafting nanoparticles onto the surface of plant fibers created a micro and nano rough surface structure on the fiber, resulting in good mechanical interlocking between plant fibers with the matrix, effectively improving the interfacial bonding force 17 . Luo et al 113 coated nano‐silica particles on the surface of corn fiber to prepare corn fiber‐reinforced PLA composites. It was found that the nano‐silica particles on the interface increased the fiber‐matrix interfacial bond strength, and prevented the extension of cracks in the composites.…”

Effect of lignocellulosic corn stalk on mechanical, physical, and thermal properties of injection moulded low density polyethylene composites: An approach towards a circular economy

“…Composites are mixtures of two or more different materials that possess superior properties compared to those of individual materials that participate in the fabrication of composites [ 19 , 20 ]. The investigations of corn stalk waste reinforced composites have pulled in due thought from academicians and industrialists for their unrivalled properties such as improved mechanical characteristics, reduced density, biodegradability and eco-accommodating materials [ [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] ] ( Table S1 ). Chen et al [ 29 ] utilised corn stalk flour and hybridized it with sisal fibres for the fabrication of PVC based composites.…”
