Abstract
Offering new materials for gas sensing performance with low cost, simple preparation, high sensitivity, selectivity and reproducibility at ambient working conditions are the main objectives of this project. Using relatively low cost, water-borne polymer system with excellent physical and chemical properties reinforced with different carbon based nanomaterials was considered as the most appropriate. The polymer matrix consisted of copolymer made of methyl methacrylate and butyl acrylate, synthesized by polymerization in dispersed media techniques, such as emulsion or miniemulsion polymerization. The polymer particles obtained are usually functionalized using small amount of functional monomers, such as glycidyl methacrylate, acrylamide or acrylic acid, which improve compatibility with the carbon nanomaterial. Additionally, to improve their distribution within the polymer matrix and sensing properties of the composite materials, post-treatment by laser ablation is performed.
