In addition, the composite membranes exhibited
striking advantages in total flux and separation factor as compared
with unfilled PDMS membrane. In this research work, NR as a
green polymer was used as the matrix for the NR/styrene butadiene copolymer (SBR)–SiO2nanocomposite membranes due to their
low glass transition temperature (Tg) and availability in latex form.
Furthermore, NR can suppress the swelling of the polymeric
structure and maintain the integrity of the membrane.
