Novel PMDA-ODA Polyimide/Polystyrene Nanocomposite Membranes for Carbon Dioxide Separation
Using N,N-dimethylacetalamide (DMAc) as the suspension media of polystyrene (PS) and poly[styrene-co-(4-vinyl-pyridin)] (PSVP) nanoparticles, insitu condensation polymerization of dianhydride and diamine was carried out and homogenous polyamic acid solution containing the nanoparticles were obtained. Novel PMDA-ODA nanocomposite membranes with various contents of nanoparticles were prepared by ...
متن کاملThermal Conductivity of Polyimide/carbon Nanofiller Blends
INTRODUCTION Combining polymers with an organic or inorganic filler to produce a polymer composite is common in the production and processing of modern plastics. Recently, filler sizes have been reduced to nanometer dimensions resulting in a new class of materials termed polymer nanocomposites (PNC). PNCs are commonly defined as the combination of a polymer matrix resin with inclusions that hav...
متن کاملFabrication and magnetic properties of Polyimide/Nickel Oxide nanocomposite
Polyimide/Nickel oxide (polyimide/NiO) nanocomposite was successfully synthesized by sol gel technique, using Pyromellitic dianhydriede (PMDA), 4,4-oxydianiline (ODA) and N,N-dimethylacetamide (DMAC) and 10 wt% Nickel titanate nanopowders (NPs). Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and vibrating sample magnetometer (VSM) we...
