Surface Modification and Engineering of Nanoscale Absorbent and Their Composite

Surface modification and engineering is the science that deals with modification involving the surface area of any material especially solids. The act of surface modification is done by bringing changes in physical, chemical or biological characteristics that are different from the original ones. The main objective of this technique is to improve performance of materials that interacts with the environment as the interaction can degrade the surface over a period of time. The significant improvement required would be to resist damages that are caused by wear, corrosion, fatigue, creep, etc. A rising demand for an alternative material for applications in engineering sectors for the want of minimizing structural weight has resulted in a prospective growth of composites. The demand is due to requirement of reduction in structural weight that would create a tremendous positive impact on energy efficiency. The major challenge in engineering sector is to achieve a competitive structure as light as possible. The materials that are micro nano-sized, incorporates many special properties that are widely used in various fields. An adsorbent is a substance used to adsorb particles from liquid or gas resulting in the betterment of the materials, which can harm the environment. The structure of activated carbon adsorbents with its pore size and surface properties aids to provide high efficacy and safety.
