“…Several processing methodologies such as solution casting [59][60][61], melt mixing [62][63][64][65][66][67], solution mixing [59,60,68], different methods of in situ polymerization of the monomer in the presence of CNTs [69,70], coagulation spinning [71], mechano-chemical pulverization [72], solid-state shear pulverization [73], electro spinning [74] etc. have been adopted for the synthesis of polymer-MWCNT composites.…”

The potential impact of light-weight structures with multifunctional properties for engineering applications drives significant research and development activities on nanocomposites. Polymer nanocomposites especially those with carbon nanotubes (CNTs) are very attractive for conductive composites with good structural characteristics. The biggest challenge facing the commercial success of CNT based composites is the intrinsic strength of their agglomerates which prevents good filler dispersion in the matrix, a key attribute for any reinforcement. This chapter is a review of the CNT incorporated thermoplastic composites processed mainly containing economic multi-walled carbon nanotubes (MWCNTs). We present an overview of CNTs (their structure, production process, properties, surface modification, applications etc.) and the mechanism of their dispersion in thermoplastic matrices. The processing of thermoplastic matrices via the conventional twin-screw compounding approach is discussed along with the influence of process parameters on MWCNT dispersion. The role of secondary processing operation on composite properties is also highlighted. The mechanical, electrical and thermal properties of the thermoplastic-CNT composites are reviewed highlighting the key findings and shortcomings. We conclude throwing some light on the developments on multi-scale reinforcements in polymeric matrices.

“…Studies have used the increase in crystallization rate as a measure of dispersion quality, [240][241][242] which would be expected to work well at low nanotube contents since the qualitative shape of an increase followed by a plateau is similar to that found for the T g versus nanotube content. An important difference, as representatively shown in Figure 9, is that the plateau in crystallization kinetic data is usually better described as a slowly increasing nearly linear section, unlike T g where the plateau is more frequently constant.…”

Effects of carbon nanotubes on polymer physics

A single carbon nanotube has many similarities with an individual polymer chain including the fact that the end-to-end length of both are often about the same and the diameter of the chain is about the same (for single-walled nanotubes) or only $10 to 20 times larger (for multiwalled nanotubes). The combination of the solid surface and the similarity of the two materials means that polymer physics are altered in manners not seen with any other type of commonly used filler. The purpose of this review is to update a chapter that appears in a recent tome by Grady (2011) and describe how polymer physics is altered in composites that contain carbon nanotubes. Subjects that will be discussed include chain configuration, glass transition, polymer diffusion, unit cells and crystalline superstructure (lamellae, spherulites and shishkebabs), and crystallization kinetics.

“…However, very few organic reactions have been performed via this process, especially in chemical modification of polymers. Furthermore, the existing research on polymer pulverization was concentrated either on improving the dispersion of particles in polymer matrix [24][25][26][27], or solely on the synthetic aspects [28][29][30]. As far as we know, taking advantages of the multi-functional mechanochemistry to simultaneously realize effective dispersion and sufficient chemical crosslinking for fabricating high performance composites has rarely been reported before.…”
