Electric Field Induced Alignment of Carbon Nanotubes: Methodology and Outcomes
In the current chapter, achievement of aligned carbon nanotube (CNT) network within the matrix via various kinds of electric fields (AC and DC) was evaluated. In this case, alignment mechanism of CNTs within the matrix and two useful techniques for justification of CNT alignment throughout the matrix were examined and presented, respectively. Afterward, effective factors in matter of CNT alignment and applicable procedures for fabrication of nanocomposites containing aligned CNTs were studied and presented, respectively. At the end, significant effects of CNT alignment on overall properties of nanocomposites that include electrical and mechanical properties were evaluated. Achieved results revealed that alignment of CNTs within the matrix can lead to significant improvement in the electrical and mechanical properties of nanocomposites at the same filler loading compared with randomly distribution of CNTs within the matrix, while production steps and conditions can also highly affect the outcome data.

Development of Clay Nanoparticles Toward Bio and Medical Applications
Clay nanoparticles are among the most applicable and cost-affordable materials, all of which have a variety of applications in case of medical science. In this chapter, key characteristics of the clay nanoparticles along with their major groups, structure, morphology, and physicochemical properties were evaluated. Thereafter, the applications of clay nanoparticles in the field of nanocomposite, polymeric matrices, and medicine were investigated, while specimen production procedures were also reviewed. The main focus of this chapter is to investigate the applications of clay nanoparticles in bio- and medical science. In fact, organically modified clay nanoparticles (organoclays) are an attractive class of hybrid organic–inorganic nanomaterials with potential applications in case of polymer nanocomposites, rheological properties modification, and drug delivery carrier.
