Methods for Preparation of Nano-composites for Outdoor Insulation Applications

Electrical insulation materials are advancing rapidly due to several advantages including light weight, better performance in polluted environment and reduced installation cost. In polymeric micro-composites, enhancing one property of the insulator may affect adversely on the other desired properties. This problem can be addressed practically with the invention of nanocomposites. This article provides a comprehensive survey of methods and techniques for the development of nano-composite materials in order to improve its insulation properties as well as its cost and aging properties. These recently evolved nano-composites provide significant improvements in combined electrical, thermal and mechanical properties. This article critically evaluates the methods, their issues and related challenges. In the end, conclusion has been drawn by proposing a set of possible solutions which need to be performed as future work.
