The MWCNTs used in the experiment was purchased from Nanoshel with diameter 10-20 nm, length 3-8 µm and (>99 %) purity. Here, we have reported the synthesis of covalently functionalized MWCNTs which can be easily coated over cotton fibers and demonstrated the application of these functionalized CNTs coated fibers for anti- static application. It is worth mentioning that functionalized CNTs contain polar groups which enable their dispersion inside solvents, enhances compatibility with polymeric matrices and improves their ability to surface coat the polymeric substrate based packaging materials. –COOH functionality) happens to be the most common functional groups which open up the possibility of further modification of CNTs via suitable solution based chemical routes. Particularly, the carboxylic acid group (i.e. The grafting of oxygen containing functional groups at the open ends and sidewalls of CNTs is a useful approach towards the covalent functionalization of CNTs. To solve these issues CNTs are often modified by covalent and non-covalent schemes (known as functionalization) which enhance their hydrophilicity, processability and compatibility. However, their hydrophobicity and the inherent inertness of graphitic skeleton pose major challenges for their direct utilization via formation of CNTs filled composites or surface coatings. In particular, CNTs with excellent electrical conductivity, low density, high corrosion resistance, outstanding mechanical properties along with high thermal, chemical and environmental stability is considered as most promising candidate for ESD control applications. As the electrical conductivity is identified as prerequisite for static charge buildup control, several efforts have been made in the past to develop conducting materials based static safe compositions. Therefore, the importance of development of the ESD free materials has been realized for ultimate utility in electronic packaging. The accumulation of static charge in electronic goods packaging (which are primarily insulating polymeric materials) causes unnecessary damage to their electronics. This has given birth to an undesirable effect known as electrostatic dissipation (ESD) effect. The use of electronic gadgets has become widespread and indispensable in the present technological era.
