Abstract The ever-increasing of global awareness towards replace the using of nonrenewable materials with a reliable, innovative, and sustainable materials for various applications. Therefore, the development of polymer composite materials is considered to be one of the most important issues from many researchers and scientists. Polymer composites have outstanding properties of ease fabrication, low cost, high specific strength properties and high corrosion resistance to be used in a wide range of engineering and advanced applications. Recently, natural fibresreinforced polymer composite has been mostly recongnized due to the outstanding properties of plant fibres; such as abundance, low cost, light weight, nontoxic, biodegradable, high tensile and flexural modulus. The interfacial bonding between the fibre and polymer plays an important role to get a valuable composite with promosing properties. Therefore, many attempts have been done including physical treatments, chemical modifications, and addition of coupling agents during processing in order to fabricate more compatible fibre composites. Polymer nanocomposites have gained popularity, as of high surface properties, durability, high thermal and chemical resistances. However, the dispersion of the nanoparticles has a higher specific surface area, which provides better matrix filler interaction and results enhanced properties to the composites. So, we focused our study to develop a new class of composite materials based natural fibres-reinforced polymer composites and their nanostructured composites. Catalysis has proven to provide clean and green chemistry, as possessing reduction of the hazards accompanied with many chemical processes. Organocatalysis by chiral organic molecule as catalysts has been provided a valuable technique in the stereoselective synthesis. Free metal organocatalyst can serve the concept of ”green chemistry” from the environmental point of view. |
