Hybrid materials based nanoparticle composites

Besides clay-based nanocomposites, there has been huge discussion on the metallic and semiconductor-based hybrid materials. The ability of polymer materials to assemble into nanostructures describes the use of polymers providing exquisite order to nanoparticles. Finally, a discussion on potential applications of polymer—nanoparticle composites with a special focus on the use of dendrite polymers and nanoparticles for catalysis should follow (Polymer-Nanoparticle Composites Part 1 (Nanotechnology), 2010) (Figure 1.15). 

Because of their unique layered structure and highly tunable chemical composition based on different metal species and interlayer anions, LDHs have many interesting properties, such as unique anion-exchanging ability, easy synthesis, high bond water content, memory effect, nontoxicity, and biocompatibility. Based on these properties, LDHs are considered as very important layered crystals with potential applications in catalysis [6], controlled drugs release [7], gene therapy [8], improvement of heat stability and flame retardancy of polymer composites [9], controlled release or adsorption of pesticides [10], and preparation of novel hybrid materials for specific applications, such as visible luminescence [11], UV/photo stabilization [12], magnetic nanoparticle synthesis [13], or wastewater treatment [14].

Carbon-based nanocomposite concepts have been successfully developed to limit or reduce these adverse effects and at the same time enhance the electron or ion transport [8]. CNT is an ideal building block in the carbon-inorganic composite/hybrid due to its mechanical, physical, chemical properties as mentioned above. CNTs are apparently superior to other carbonaceous materials such as graphite or amorphous carbon and are more adaptable to the homogeneous dispersion of nanoparticles than other carbonaceous materials [36],...
