Influence of bleaching treatment by hydrogen peroxide on chitosan/durian husk cellulose biocomposite films

Abstract

This study covered the preparation and characterization of durian husk cellulose (DHC)-filled chitosan (CS) biocomposite films. The effects of the DHC content and bleaching treatment via hydrogen peroxide (H 2 O 2 ) on the tensile and thermal properties of the CS/DHC biocomposite films were investigated. The results showed that the tensile strength and percentage of elongation at break decreased with increasing DHC contents, but the modulus of elasticity of the CS/DHC biocomposite films increased along with the DHC contents. The bleaching treatment of the durian husk is to remove the lignin content to form bleached DHC, resulting in an improvement of tensile strength, modulus of elasticity, and thermal properties of bleached CS/DHC biocomposite films. The functional groups of the unbleached and bleached DHC filler were proved by the Fourier transform infrared (FTIR) analysis, and the thermal stability and glass transition temperature (T g ) of the CS/DHC biocomposite films were measured by the thermogravimetry analysis (TGA) and differential scanning calorimetry (DSC) analysis, respectively.

Preparation and Characterization of Wood Plastic Composite Made Up of Durian Husk Fiber and Recycled Polystyrene Foam.

“…The discarded durian husks usually end up in landfills or burnt which contributed to environmental pollution. From the literature found durian husk actually contains huge amount of lignocellulose fiber and those compositions are similar to wood fiber [11][12]. In regards, this research is underway to utilise durian husk fiber to WPC.…”

Preparation and Characterization of Durian Husk Fiber Filled Polylactic Acid Biocomposites

“…As expected, the tensile modulus of the biocomposites gradually increases with increasing amount of DHF. It is because the modulus of DHF is usually higher than plastic [12]. Therefore, the presence of higher amount of DHF contributed to higher modulus of the PLA/DHF biocomposite.…”

“…Thus, by making the PLA in to biocomposite, the addition of natural filler can be partially replace the PLA without influences its biodegradability and highly reduced the cost of final product. Durio zibethinus Murray, also called as durian, the famous fruit among the Southest Asia countries especially in Malaysia, Thailand, Indonesia and Philippine [12]. The durian fruit is made up of 40% of flesh and 60% of husk.…”

Properties of corn husk fibre reinforced epoxy composites fabricated using vacuum-assisted resin infusion

“…2 Recent research works have shown that many natural fibres from agricultural waste have been utilised to produce composite materials, such as durian husk fibre, corn husk fibre and pineapple leaf fibre. [3][4][5][6] From the literature, the corn husk fibre was fabricated into composite materials by mixing with recycled plastic material. 5 However, the study of fabricating composite from corn husk fibre using vacuum assisted resin infusion (VARI) technique has not been reported in the open literature.…”

“…Natural fibre absorbs a significant amount of moisture, has poor thermal stability, shows variation in quality, poor interfacial adhesion, and less compatibility with hydrophobic polymer. 4 This is because the natural fibre comprises strong polarised hydroxyl groups in its chemical structure, thus exhibiting hydrophilic characteristic. 10 The poor interfacial bonding between natural fibre and polymer matrix is a main issue that influences the mechanical strength of composite materials.…”
