Effect of carbon black and nanoclay on mechanical and thermal properties of ABS–PANI/ABS–PPy blends

Abstract

Acrylonitrile butadiene styrene (ABS)-polyaniline (PANI) and ABS-polypyrrole (PPy) blends exhibit poor mechanical and thermal properties due to their weak interfacial adhesion and inhomogeneous mixing. The properties have been improved by addition of carbon black (CB) and nanoclay (NC). Composites are prepared by mixing CB and NC with ABS-PANI and ABS-PPY blends. The morphology and crystalline characteristics are studied using field emission scanning electron spectroscopy (FESEM) and X-ray diffraction, respectively. In addition, all the composites have been analyzed for their mechanical and thermal performance. The tensile strength of ABS-PANI has been increased by 7.18% and 65.83% with addition of CB and a combination of CB-NC, respectively. FESEM images are found supportive with these trends and show homogeneous dispersion of CB in the polymer matrix, assisted by NC. Dynamic mechanical analysis results also show slight improvement of glass transition temperature (T g ) with addition of fillers.

Effect of Printing Parameters on Tensile, Dynamic Mechanical, and Thermoelectric Properties of FDM 3D Printed CABS/ZnO Composites

“…The reduction of the stiffening effect of fillers resulted in lower E’ value. When the infill density increased, a close raster and deposited fibers were generated, which led to a denser structure and improvement in E’ of the printed parts [ 29 ]. Rectilinear samples showed a slightly lower storage modulus value at all temperatures below glass transition temperature, Tg, compared to line samples, due to less stiff structure.…”

“…No significant impact was observed on the Tg for printing pattern and infill density change. Increasing Tan δ means the material has more energy dissipation potential, whereas decreasing Tan δ means when load is applied, the material has more potential to store the load, rather than dissipating it [ 28 , 29 ]. Results in Figure 8 e showed Tan δ decreased with infill density.…”

Emerging Research in Conductive Materials for Fused Filament Fabrication: A Critical Review

“…[ 329 ] Peighambardoust et al [ 330 ] prepared a PA6‐matrix composite with in situ polymerized PPy/MMT and observed conductivity of 1.66 × 10 −4 S cm −1 at 25 wt% PPy and 5 wt% MMT. Debnath et al [ 331 ] melt blended CB and nanoclays to improve the mechanical strength of ABS/PPy and ABS/PANI blends. As CB and nanoclay fillers worked as a heat absorber, the processability of ABS/ PPy and ABS/PANI blends was improved, but it is unclear what the effect was on electrical conductivity.…”

Nanoclay Co-Doped CNT/Polyaniline Nanocomposite: A High-Performance Electrode Material for Supercapacitor Applications

“…Wang et al also reported on the electro‐rheological properties of polyaniline nanofiber/kaolinite hybrid nanocomposite prepared by rapidly mixed in‐situ polymerization . Similarly, Debnath et al also described the effect of carbon black and nanoclay on mechanical and thermal properties of ABS‐PANI/ABS‐PPy blends . Despite of such superior properties, fundamental understanding has yet to emerge with the prospects of development of nanostructured material with improved polymer/silicate interface.…”
