“…The insulation of CNTs by coating them with an insulating polymer could preserve the order between the nanotubes and significantly enhance the electrical conductivity of the nanocomposites [31] . Therefore, the insulation of CNTs provide a sufficient length of aligned conductors with a proportional scaling of conductivity [32] as was predicted by Equation (2). Figure 2 depicts the energy gap and the relation to the conductivity of the materials.…”

Why is the nanoscale special (or not) ?Fundamental properties and how it relates to the design of nano-enabled drug delivery systems Abstract: Nanoscience studies describe natural phenomena at the submicron scale. Below a critical nanoscale limit, the physical, chemical, and biological properties of materials show a marked departure in their behavior compared to the bulk. At the nanoscale, energy conversion is dominated by phonons, whereas at larger scales, electrons determine the process. The surface-to-volume ratio at the nanoscale is immense, and interfacial interactions are markedly more important than at the macroscopic level, where the majority of the material is shielded from the surface. These properties render the nanoparticles to be significantly different from their larger counterparts. Nano-enabled drug delivery systems have resulted from multidisciplinary cooperation aimed at improving drug delivery. Significant improvements in the thermodynamic and delivery properties are seen due to nanotechnology. Hybrid nanodelivery systems, i.e., membranes with nanopores that can gate stimuli-responsive drug release could be a future development. Nanotechnology will improve current drug delivery and create novel future delivery systems. The fundamental properties and challenges of nanodelivery systems are discussed in this review.

“…Although this model can follow the conductivity of PCNT, it cannot consider the physical properties of CNT, such as its nano-size or interphase. Some people have also developed micromechanics models that can predict the electrical conductivity of PCNT by assuming more parameters such as the waviness of CNT and the tunneling effect; [14][15][16] however, these employed complicated equations that are not applicable for practical applications. Moreover, these previous models commonly did not reect the inuence of the interphase, which can change the percolation level and the percentages of percolated nanotubes.…”

In this work, a simple methodology is presented that describes the main tunneling conductivity of polymer/ CNT nanocomposites (PCNT) assuming the tunneling distance, interphase surrounding the CNT, and CNT waviness. The conductivity related to the tunneling distance is obtained by a simple equation, and its role is considered by using an extended CNT (including CNT and the tunneling space). Additionally, the effects of the interphase and CNT waviness on the percolation threshold, effective filler fraction, and percentages of poor percolation threshold present desirable conductivity.

The extrusion process is one of the pre-mixing processes that aid in improving the filler dispersion in conductive polymer composite (CPC). Electrical conductivity level still needs much improvement in mixing process through mechanical mixer. This study was conducted to optimise the extrusion process parameters (temperature and rotational speed) of milled carbon fibre (MCF) and polypropylene (PP) using experimental design (Taguchi method
