Carbon Nanotube Polymer Composites Recent Developments in Mechanical Properties... 

Carbon nanotnbes are regarded as ideal filler materials for polymeric fiber reinforcement dne to their exceptional mechanical properties and cylindrical geometry (nanometer-size diameter). Polymer chains in the vicinity of carbon nanotubes (interphase) have been observed to have a more compact packing, higher orientation, and better mechanical properties than bulk polymers due to the carbon nanotube polymer interaction. The existence of interphase polymers in composite fibers, their strnctnral characterization, and fiber properties are summarized and discussed in the literature (Liu and Satish 2014). Besides improvements in tensile properties, the presence of carbon nanotubes in polymeric fibers also influences other factors (thermal stability, thermal transition temperature, fiber thermal shrinkage, chemical resistance, electrical conductivity, and thermal conductivity).

For CNTs not well bonded to polymers, Jiang et al. [137] established a cohesive law for carbon nanotube/polymer interfaces. The cohesive law and its properties (e.g., cohesive strength, cohesive energy) are obtained directly from the Lennard-Jones potential from the van der Waals interactions. Such a cohesive law is incorporated in the micromechanics model to study the mechanical behavior of carbon nanotube-reinforced composite materials. CNTs indeed improve the mechanical behavior of composite at the small strain. However, such improvement disappears at relatively large strain beeause the eompletely debonded nanotubes behave like voids in the matrix and may even weaken the composite. The increase of interface adhesion between CNTs and polymer matrix may significantly improve the composite behavior at the large strain [138].

In this chapter, the recent advances in the field of carbon nanotube/polymer nanocomposite aerogels and related materials are described. An emphasis is paid to the relationship between the preparation method and the most characteristic properties of these materials such as density, surface area, electrical conductivity, mechanical strength, and so forth.
