9. KEY CONCEPTS CHEMICAL FUNCTIONALIZATION of CNT Using ammonia solution to introduce hydroxyl (OH) and amine (NH) groups on GO and CNT. CHEMICAL FUNCTIONALIZATION OF COTTON FABRIC By Using Bovine Serum Albenium BSA, as reported in previous studies and cited in literature, 2018, Iftikhar. Et. Al . PHYSICAL MODIFICATIONS Plasma, Argon, Oxygen and Nitrogen inert gases

10. KEY CONCEPTS

11. KEY CONCEPTS CARBON NANO TUBES (CNT) Functionalized (Dopamine, BSA, Polydopamine and Acids. Amine Groups (NH3) can be incorporated using Ammonium per sulphate APS, Ammonia.

12. KEY CONCEPTS DISPERSION TECHNIQUES GO can easily disperse in water-based solutions, however, graphite, graphene and rGO and CNTs dispersion is difficult to be dispersed in water-based solution. Therefore, Isopropyl Alcohols, Ethanol, Methanol, and Phenolic substances are widely used to disperse. Deionized Water for GO, and Graphite, RGO and Graphene are dispersed in Methanol or Ethanol Poor dispersion ability also reduces the interaction with applied surfaces, For example, cotton, polyester, Blends, and Nonwoven PP fibers, Therefore, Surface modification is made using chemical, and physical modifications. For example, Dopamine, Poly Dopamine, Ammonia, and APS.
