Abstract

The usage of polyamide 6 membrane has been used in the separation process industry for decades. In such process, the membrane is exposed to high pressure and temperature condition. Another complication is the process of producing a uniform microporous membrane. Recent improve being researched to improve these membrane are adding nanocomposite filler. This comes to the objectives of this study which is to study, prepare and characterize polyamide 6 nanocomposite membranes. The polymer is prepared by mixing formic acid and polyamide 6 pellets, and lastly mixing montmorillonite as the filler by immersion precipitation process. The microstructure, morphology and mechanical properties of polyamide 6 nanocomposite membrane is being studied using Dynamic Mechanical Analyzer (DMA), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). It is found that at 1% wt. of filler, the pore size, numbers of pores and distribution is evenacross the surface of the membrane. But as the amount of filler increase, the pore size and numbers is reduced even more and distributed unevenly across the surface. From previous study, the Tg increases with the increment of filler amount. The mechanical properties have also improved in terms of storage modulus andyield strength. Finally from XRD, the orientation of arrangement also affect where more filler is added it changes from exfoliated form to intercalated form. As a conclusion, from the SEM results, filler content can influence pore size, their numbers and distribution of pores. Further studies and experiment need to be conducted in order to study the effect of clay on mechanical properties. m
