Chapter 4 - Conventional techniques for nanomaterials preparation

Abstract

Nanomaterialshave been gaining interests for their numerous uses in different fields such as electronics, automotive, biomedical, and aerospace. Nanomaterials having extremely exceptional properties in thermal stability, catalytic, adsorption, and mechanical strength depend mainly on size, diameter, and morphology. Based on their widespread approach researchers are going toward its advancement based on preparation techniques. Several methods have been used for manufacturing of nanomaterials, which include chemical vapor depositions (CVDs), arc-discharge, and laser ablation. They can be produced directly as particles or distributed in a variety of hosts, such as liquids, glass, and gas. This chapter reviews extremely brief synthesis of nanomaterial technique on the conventional method. The methods include CVD, arc discharge, laser ablation CVD enhanced with microwave, plasma, fluidized bed, phase growth approach, laser ablation, disc charge, etc. In addition, future challenges of nanomaterial preparation are discussed. Hence preparation of various nanomaterials via a conventional technique is a breakthrough in the nanotechnology research field. From this chapter, it is concluded that microwave technique is a great approach to form cost effective and easy to synthesis nanomaterials
