A Facile Approach to the Fabrication of MWCNT/PMMA Nanocomposite by in Situ Microemulsion Polymerization

Highly field polymers use for several purposes such as lubricants, anti radars and etc[1-4]. We focused on anti radar purpose.Radar is a detector which can find distances by radio waves. This system which works based on the electromagnetic waves provides some information about an object location bysending specific form of waves to the target and receiving the returned waves. The frequencies of radar waves or generallyelectromagnetic waves are in the range of 2-18 GHz. Antiradar coatings are applied to avoid the electromagnetic waves penetration. This research investigates some of the compositeswhich are used as coating. In this research Multi Wall Carbon Nanotubes (MWCNT)/Poly Methyl Methacrylate (PMMA) composites was synthesized, and we measured their wave s absorption. A good absorption was the significant goal of thisresearch and each coating has a good absorption. Important points in design and construction of the absorbents are: low thickness, low weight and volume, wide band, flexibility, low cost and having enough strength in every climate and environment.
