Film Nanocomposites

Tensile and electrical properties of graphene nanopowder (GNP) and multiwalled carbon nanotubes (MWCNT) filled epoxy thin film nanocomposites were investigated. In addition, synergy effects of various mixture ratios of GNP–MWCNT hybrids on the properties of the epoxy thin film nanocomposites were evaluated. It was found that the addition of GNPs or MWCNTs decreased the tensile properties compared to that of unfilled epoxy. The electrical percolation threshold of MWCNT/epoxy was found to be 0.8 vol%. Addition of only 0.1 vol% GNPs results in significant improvement in the electrical properties of the composites. Enhanced tensile and electrical properties in the GNP–MWCNT/epoxy hybrid were achieved with GNP–MWCNT ratio of 0.1:0.4. Morphological analysis confirmed the uniform dispersion of both GNPs and MWCNTs within the epoxy matrix. For the hybrid GNP–MWCNT filler system (i.e., with the 0.1:0.4 ratio), MWCNTs were seen to align themselves on the GNPs surfaces creating an interconnected strong nanofiller network in the epoxy.

Thin Film Nanocomposite

Multiwalled carbon nanotubes (MWNTs) grafted by Poly(methyl methacrylate) (PMMA) can well disperse in organic solutions like toluene，which were synthesized via a microemulsion polymerization of methyl methacrylate (MMA) in the presence of acid-modified multiwalled carbon nanotubes (c-MWNTs). The polyamide thin-film nanocomposite (TFN) membranes with embedded PMMA-MWNTs were prepared using piperazine (PIP) and trimesoyl chloride (TMC) on a polyacrylonitrile (PAN) porous substrate via interfacial polymerization for selective permeability. PMMA-MWNTs’ structure was analyzed by Fourier transform infrared spectrophotometry (FTIR), Raman spectrophotmetry (RAM), Scanning electron microscope (SEM) and thermo gravimetric analysis (TGA). Orthogonal experiment was used to study the effect of PIP concentration, TMC concentration and concentration of PMMA-MWNTs in organic phase. The results showed that the membrane performances is good, Na2SO4 rejection is above 98% and water flux is up to 150% improvement over the TFC membrane as PIP in aqueous phase was 2g/L, TMC and PMMA-MWNTs in organic phase were 4g/L and 0.67g/L, respectively . Demonstrated PMMA-MWNTs in the nanofiltration membrane can improve selective permeability.
