“…Figure 15 shows the TG curves for pure and blend samples heated in nitrogen atmosphere at a heating rate of 10 C= min. The TG curves are shifted to higher temperatures with increasing ionomer content, which is not only due to higher thermal stability of ionomer as compared to pure ASA, but also due to the interfacial interaction between acrylate of ASA and the methacrylic acid group of the ionomer, thus improving the interfacial interaction [53] between the blend components and thus the mobility of the chain molecules are restricted [54] resulting in improved thermal stability of the blends.…”

The present study deals with acrylonitrile-styrene-acrylic elastomer (ASA) terpolymer and an ionomer based blend to develop a weather resistant material with good heat sealability and excellent adhesion properties. The mechanical properties of ASA/ionomer blends were reduced with increase in ionomer content, whereas the thermal stability was improved. On addition of ionomer, the effects of shear rate and temperature on melt viscosity were also investigated. The mechanical modulli were also carried out to justify and correlate with ionomer content. The thermal stability, investigated by thermogravimetric analysis, showed that the thermal stability was increased with the incorporation of ionomer.

“…Therefore, the CNTs can be used as ideal reinforcing nanocomponent for fabrication of multifunctional polymer nanocomposites. The CNTs can more efficiently improve the properties of polymers as compared to other nanofillers because of their excellent properties and large aspect ratios [2,[6][7][8] .…”

Plasma-functionalized multi-walled carbon nanotubes (p-MWCNTs) are used to fabricate poly (methyl methacrylate) (PMMA) based nanocomposites with different p-MWCNTs loadings. First, MWCNTs are functionalized by He-dielectric barrier discharge plasma followed by an exposure to NH 3 and then the PMMA/p-MWCNTs nanocomposites are prepared by a phase inversion-based solution method. The rheological and electrical properties of the PMMA/p-MWCNTs nanocomposites are measured. The results showed that the electrical and rheological percolation thresholds appear at a very low value of 0.5 wt.% p-MWCNTs loading. This value is one of the lowest reported percolation thresholds for PMMA/MWCNTs nanocomposites, indicating excellent dispersion state of the p-MWCNTs in PMMA.

“…The integration of one-dimensional nanotubes with zero-dimensional nanoparticles into hybrid structure has received escalating significance, particularly the noble metal nanoparticles=CNTs composites [3][4][5][6][7][8][9]. Among the noble metal nanoparticles, silver (Ag) nanoparticles have been extensively studied due to their potential utility as electrocatalysts, broad-band optical limiters, electrode materials, biosensors, and electrode in lithium-ion batteries [10].…”

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).
