Spectroscopic and Diffractional Characteristics of Membranes and Polyamide 6/Regional Bentonite Clay Nanocomposites

Abstract: Polymeric membranes are attracting attention of researchers and industries due to their lower costs. However, they also have lower mechanical resistance and chemical solvents, when compared with other materials. An improvement of polymer properties can be obtained by adding an inorganic nanoload in the structure. This study produced polyamide 6 / bentonite clay nanocomposites with a nominal content of 3%, and this was used in the processed form and in the organically modified form by cation exchange. The nanoc… Show more

“…21.8° of the crystalline plan (001), which can be attributed to phase γ (gamma) of PA6 36,37 . The addition of 10% w/w of CaCl 2 in the solution of membrane preparation did not cause significant changes with regard to the crystalline behavior and the main crystalline phase is α, as illustrated by the X-ray diffraction curve of pure PA6 membranes and their hybrids.…”

“…The addition of 1, 3, and 5% in weight of OMMT (Figure ) on the PA6 membrane caused a morphological modification on its surface, presenting a flat structure with greater number of pores, as well as, the formation of a pore structure of spherical shape, well distributed in the porous layer along its cross‐section …”

“…Analisando a PA6 pura e seus híbridos, foi possível observar que a fase cristalina predominante é a alfa [24][25][26]29]. Além disso, foi constatada nas membranas com 3% e 5% de argila, a presença de um pico em aproximadamente 27°, referente ao elemento quartzo da argila.…”

“…A adição de 1%, 3% e 5% em peso de argila (Figura de 5 a 7) na membrana de PA6 provocou uma modificação morfológica na sua superfície, apresentando uma estrutura com poros mais abertos e uma maior quantidade deles, bem como, a formação de uma estrutura com poros interconectados de formato esférico e bem distribuídos provenientes da camada porosa mostrada ao longo de sua seção transversal [23][24][25][26].…”
