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.
