Microstructure and Multiwall Carbon Nanotube Partitioning in Polycarbonate/Acrylonitrile-Butadiene-Styrene/Multiwall Carbon Nanotube Nanocomposites

The research initially involved the decoration of silver nanoparticles on carbon nanotubes using N,N-dimethylformamide. A new heteroaromatic azo-polymer was prepared and employed as a matrix while Ag-CNTs as filler. Two techniques were exploited to prepare nanocomposites (i.e., melt compounding and solution mixing). The solution mixing method resulted in better dispersion leading to higher mechanical strength 55.09-58.22 MPa relative to melt system 40.11-46.28 MPa. Filler content from 1 to 5 wt% increased electrical conductivity from 3.8 to 5.2 Scm À1 . 10% gravimetric loss was found to increase from 532 to 578 C (solution) and 503 to 544 C (melt).

“…There is great attention to employing properties of CNT by incorporating into some form of matrix. It has been revealed that the introduction of CNTs into a polymer matrix improves the thermal and mechanical properties as well as electric conductivity of the polymer matrix [8][9][10][11][12][13][14][15][16] . Using the outstanding properties to prepare high-performance polymer composites has been limited by the poor dispersion of CNT.…”

Multiwall carbon nanotubes (MWCNT)s-reinforced poly(esterimide)s (PEI)s composites were synthesized under sonication.Step-growth polymerization of amino acid based diacid with 4,4 0 -thiobis(2-tert-butyl-5-methylphenol) was carried out to give a chiral PEI. S-Valine amino acid was covalently attached to carboxylated MWCNTs by an amide bond and effectively dispersed in aromatic polymer as a continuous medium to prepare PEI/MWCNT composites. Microscopic observations showed that the dispersion of the CNTs was improved by the amino acid groups on the surface of MWCNTs and functional groups on the PEI. In comparison with the neat PEI, the MWCNTs reinforced composites revealed higher thermal stability.

Among nanocarbon filler, carbon nanotubes (CNTs) are considered to be an ideal reinforcement due to their miniscule size, and excellent electrical, thermal, and mechanical properties. However, CNTs can be utilized in polymer nanocomposites only if they are homogenously dispersed into polymer matrices. The multi-walled carbon nanotube (MWCNTs) has been concentrated as reinforcement for an important type of thermoplastic polyvinylidene fluoride (PVDF). This review firstly focuses on CNTs modification both by mechanical methods and chemical functionalization to improve their dispersion. Moreover, processing methods for PVDF/CNTs nanocomposite have been discussed. MWCNTs facilitate the electrical conductivity, thermal, rheological and mechanical properties of PVDF.
