Poly(vinylalcohol)/reduced graphite oxide nanocomposites have been synthesised by reducing in the presence of polymer matrix and coagulating system with 2-propanol. It has observed that some interactions occur between reduced layers, mainly hydrogen bonding. These are responsible for a remarkable change thermal behaviour nanocomposites. In addition, high electrical conductivity achieved at concentrations beyond 7.5 wt% (∼0.1 S cm−1), percolation threshold 0.5 1 wt%.
The performance of chemical sensors based on polymer nanocomposites with CNTs and graphene is revised, highlighting the role polymeric material.

The effect of polyetherimide (PEI) as a compatibilizing agent on the morphology, thermal, electrical and dynamic mechanical properties poly(ether ether ketone) (PEEK)/single-walled carbon nanotube (SWCNT) nanocomposites, has been investigated for different CNT loadings. After pre-processing step based ball milling pre-mixing under treatment in ethanol, samples were prepared by melt extrusion. A more homogeneous distribution CNTs throughout matrix is found composites containing PEI, revealed...
Abstract The nucleation activity of the sorbitol derivatives 1,2,3,4‐bis(3,4‐dimethylbenzylidene sorbitol) and methyldibenzylidene are compared with that talc, a conventional nucleating agent for monoclinic crystalline phase isotactic polypropylene. thermal parameters associated dynamic crystallization process studied as function cooling rate by differential scanning calorimetry, efficiency is assessed comparison self‐nucleation, highest values being observed over whole concentration range....
Hydroxylated poly(ether ether ketone) (PEEK-OH) samples, with different degrees of functionalization, have been synthesized by selective carbonyl reduction. The ATR-FTIR and NMR spectra corroborated the reduction success, showing a decrease in intensity peaks related to ketone group simultaneously appearance new signals associated hydroxyl group. TGA curves indicated thermal stability increasing hydroxylation degree (HD), attributed changes spatial organization molecules less intense...
Abstract A new family of thermoplastic nanocomposites based on isotactic polypropylene (iPP) and inorganic fullerene‐like tungsten disulfide (IF‐WS 2 ) has been successfully prepared. very efficient dispersion IF‐WS material was obtained by mixing in the melted polymer without using modifiers or surfactants. The addition nanoparticles induces a remarkable enhancement thermal stability iPP, as well an increase crystallization rate matrix when compared with pure iPP. nucleating efficiency...
Multicomponent nanocomposite materials based on a high-performance epoxy system and single-walled carbon nanotubes (SWNTs) have been prepared. The noncovalent wrapping of nitric acid-treated SWNTs with PEO-based amphiphilic block copolymer leads to highly disaggregated filler boosted miscibility in the matrix, allowing its dispersion without organic solvents. Although direct results modestly improved matrix mechanical properties, incorporation wrapped produces huge increase toughness (276%...
The combination of high-performance thermoplastic poly(ether ether ketone) (PEEK) with inorganic fullerene-like tungsten disulfide (IF-WS2) nanoparticles offers an attractive way to combine the merits organic and materials into novel polymer nanocomposite materials. Here, we report processing PEEK/IF-WS2 nanocomposites, which overcome nanoparticle agglomerate formation provide PEEK−particle interactions. IF-WS2 do not require exfoliation or modification, making it possible obtain stronger,...
Arc discharge single-walled carbon nanotubes (SWNTs) have been functionalized with terminal primary amines through four experimental approaches that induce either tip/edge or sidewall functionalization. A full characterization of SWNTs has carried out several techniques. The aminated solvent-free incorporated into a trifunctional high-performance epoxy system, and the mixture studied using differential scanning calorimetry (DSC) isoconversional kinetic calculations. thermodynamic parameters...
