Hopes for Application of Polymeric Nanocomposites in Airplane Industry
TEHRAN, May 4 (FNA)- Iranian researchers at Isfahan University of Technology managed to synthesize poly (ether ether ketone) /silica polymeric nanocomposite in powder form by mechanical alloying with applications in airplane manufacturing industry.
"Poly (ether ether ketone) (PEEK) is an advanced engineering polymer. The most important features of this polymer are excellent resistance to chemical environments and highly favorable erosive and frictional behavior," Mehdi Hedayati, one of the members of the research team, told INIC.
"However, fairly high melting temperature (about 340°C) and very low solubility in common solvents, arise problems for the synthesis of these polymer composites by common methods. The main objective of this research was to practice a new method for the synthesis of polymeric base nanocomposites so that the product is prepared in powder form," he added.
"Reinforcing nanoparticles were distributed and dispersed into the polymeric matrix by means of solid state processing and high energy ball milling (for 15 hours)."
Elaborating on the research results, Hedayati said, "The analyses show that molecular destruction won't evolve in the polymeric structure if the process parameters are adjusted. Also, an appropriate distribution and dispersion of nanoparticles in polymeric matrix is achieved by modification of surface chemical behavior of silica nanoparticles."
Resolving the problems and limitations related to the melting or dissolution of polymer in previous methods, simplicity of the process and controlling its variables, and consequently facilitation of nanocomposite synthesis, possibility of making the product in powder form and its direct use in other applications like coating are a number of advantages of this research.
Stressing the necessity for the commercialization of the product, Hedayati said, "We held good negotiations with Iran airplane manufacturing industries (HESA) and a contract with the novel industries department of the Ministry of Industries and Mines is in the final stages of endorsement."
