“…Pure PMMA matrix exhibits high flexture modulus due to the intrinsic properties of PMMA. [ 36 ] The flexural modulus of the composites increased distinctly with the addition of K‐CB filler (Figure 5B). The K‐CB filler particles could act as good reinforcing agent in the PMMA matrix.…”

“…At high K-CB loading, filler particles are easily agglomerated in its primary and secondary structure. [35,36] With increasing K-CB content, the interaction between filler-filler may be severe compared to polymer-filler interaction, which deteriorates its mechanical strength. The filler agglomeration acts as stress concentration points in nanocomposites resulting in inefficient stress distribution.…”

Nanostructured carbon-based polymeric nanocomposites are gaining research interest because of their cost-effectiveness, lightweight, and robust electromagnetic interference (EMI) shielding performance. Till now, it is a great challenge to design and fabricate highly scalable, cost-effective nanocomposites with superior EMI shielding performance. Herein, highly scalable EMI shielding material with tunable absorbing behaviors comprising of low-budget ketjen black (K-CB) reinforced poly(methyl methacrylate) (PMMA) nanocomposites have been prepared using simple solvent assisted solution mixing technique followed by hot compression technique.

“…In this paper, we report on the effect of PMMA‐spacer into the CB filled epoxy adhesives with a constant CB loading at 15 vol.%, which was the optimum loading determined from previous study, and the PMMA‐spacer content ranged from 10, 20, 30, 40, and 50 vol.% were used. The focus of this study is to investigate the effect of PMMA‐spacer content towards the electrical conductivity properties at fixed 15 vol.% CB loading, where the selective localization mechanism occurred at room temperature.…”

A new approach of mimicking the selective localization mechanism of conductive filler into one phase of immiscible polymer blend system is proposed here, where a moderate fine of polymethylmethacrylate (PMMA) powder is prepared and used as the spacer in the carbon black (CB) filled epoxy adhesives system that can be applied at room temperature. The main purpose of PMMA‐spacer is to promote the formation of conductive networks via aiding the 3D self‐assembly of CB filler, selectively in the continuous phase of epoxy. PMMA‐spacer content ranged from 10, 20, 30, 40, and 50 vol.% were investigated under electrical, mechanical, and thermal properties for both unfilled and 15 vol.% CB filled system. With the incorporation of 10 vol.% PMMA‐spacer, the filled system shows promising improvement in electrical conductivity, with three order of magnitude increment at 15 vol.% CB loading. Toughening mechanism of epoxy was observed, where crack deflection upon the PMMA‐spacer is observed under scanning electron microscopy characterization and agreed by fracture toughness calculation. Thermal stability and coefficient of thermal expansion were improved at the minimum addition of PMMA‐spacer content, at 10 vol.%, while a small reduction in flexural strength is observed because of the poor interface interaction between the PMMA‐spacer and epoxy matrix. Interestingly, a limited interaction between the PMMA‐spacer with epoxy at the curing temperature of 100°C is observed, indicating the solubility of PMMA‐spacer in epoxy before crosslinking process occurred.
