The composites film was prepared by solution casting at 0 to 12 wt/v% content of XCs filler and characterized under tensile analysis. The tensile strength (TS) and Young Modulus (YM) increased lineraly with the content of XCs filler (2 to 8 wt/v%). Contrarily, tensile strain (EB) and toughness (K) reduced corresponding to similar content of filler. The Fourier Transform Infra-Red (FTIR) and Field Emission Scanning Electron Microscope (FESEM) analysis proved, such results were influenced by the inter hydrogen bonds and electrostatic interactions between Cs and XCs.

Thermal properties of the composites were examined using thermogravimetry (TG), differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). Addition of XCs to 10 wt/v% increased 2.7% on thermal properties of Cs film. Consequently, the glass transition temperature (Tg) is enhanced from 51 to 58°C for a similar composition of XCs. Results could be related to good interfacial interactions of Cs matrix and XCs filler through formation of interhydrogen bonds and electrostatic interactions.

It is concluded that the properties of Cs biocomposites with a synthetic constituent

In recent years, research attention has been focused on processes that lead to an improved oxidative degradation of organic pollutants. Therefore, semiconductor photocatalysis technology has aroused scientists’ interest in environmental remediation. Although several semiconductors have proven to be ideal candidates for the treatment of water pollution, the efficient separation and recycling of this fine-powdered photocatalyst is still a scientific problem when applied in practice, including separation process, selectivity, and dispersion. A photocatalyst with magnetic properties allows the use of the technique of magnetic separation, which is one of the most effective and simple methods for removing suspended solids from wastewater without the need for further separation processes. The magnetic photocatalyst allows its use as a s...

Alkalization treatment was done to kenaf fibre using 6 % of NaOH. Kenaf content was varied between 5 % and 25 % by weight. Tensile, flexural and impact properties of the composites were studied. It was found that the tensile modulus increases with increasing kenaf content for treated composite system which reaches an optimum at 10 % kenaf content. Tensile modulus of treated composite is higher than untreated particularly at 10, 15 and 20 % except at 5 % kenaf content. The flexural modulus also shows an increasing when higher kenaf content were used for treated composite which reach an optimum at 15 % kenaf content. Flexural modulus of treated composite is higher than untreated at all kenaf content. The impact strength shows an increasing at 10 % kenaf content and reaches an optimum at 15 % fibre. However the value is lower than the untreated composites at 5 and 20 % kenaf content. Scanning Electron Microscope (SEM) ...
