Abstract
Research in bio-based composites is rapidly rising in terms of fundamental experiments and industry applications. Natural fibres are one of the common bio-based materials used in composites. Natural fibres have many advantages, including low cost, biodegradable, good thermal conductivity, and may also be used as an alternative to synthetic polymer composites. However, the hydrophilic characteristic of natural fibres can lead to poor interfacial adhesion between natural fibres reinforced and matrix phases, which can affect the properties of bio-based composites. To overcome this problem, the surface modification of natural fibres is required to improve the hydrophobic properties of the composite. A few studies revealed that silane improved the hydrophobicity, tensile strength and thermal stability of bio-based composites. The highest water contact angle of the treated bio-based composite was reported at 135 degrees. Meanwhile, the tensile strength of silane-treated bio-based composite can increase up to 40%. The onset decomposition temperature of silanes treated with bio-based composite is 20 degrees C higher compared to untreated bio-based composite. This article provides an insightful review of the surface treatment of bio-based composites via silane treatment on mechanical properties, thermal properties, water absorption, and water contact angle.
