The engineering thermoplastic polyoxymethylene POM is a newlinepolymer of formaldehyde Even though it is believed to replace the usage of newlinemetals it also degrades easily under many circumstances like heat acids newlinealkalis oxygen abrasion enzymes radiations etc This work aims to study newlinethe degradation of four group of samples A pure POM B POM newlinenanocomposite with Copper oxide Nanoparticles CuO C POM newlinenanocomposite with Mesoporous Silica Nanoparticle MSN and D POM newlinenanocomposite with yttrium oxide nanoparticles Y2O3 at periodical newlineintervals Nanoparticles were synthesized and characterized with Scanning newlineElectron Microscopy SEM and X Ray Diffraction XRD for their size and newlineShape These nanoparticles were mixed with pure POM pellets using spin newlinescrew extruder The resultant product was POM nanocomposite These newlinenanocomposites were characterized by SEM to find out nanoparticle spread in newlinePOM material newline newline%%%appendix p145-149, reference p150-162.
