These improvements occur mainly because of the excellent properties of graphene nanoflakes, such as tensile strength (150 GPa), Young's modulus (1.0 TPa), thermal conductivity (4,840–5,300 W/m K), electrical conductivity (1.3 × 106 S/cm), electrical current density (1013 A/cm2), surface hydrophobicity (>120°), and surface smoothness/roughness (<1 nm). Poly (methyl methacrylate) seems a suitable thermoplasticpolymer due to high strength, high heat and abrasion resistance, and good mechan-ical properties. Several tables are presented that give an overview on the wealth of methods and materials. It has two subcategories: transition temperature of the polymer.

Hence, we should choose the, llers based upon their application. The enhanced electrochromic properties are mainly attributed to the formation of the donor-acceptor system between the PANI nanofiber shell layer and the ATO/TiO2 nanorod, and the porous space among the ATO/TiO2@PANI nanocompsites and the PANI nanofibers, which can improve the efficiency of redox reaction, make the ion diffusion easier and provide larger surface area for charge-transfer reactions, respectively. The superior properties of the CNPs/PVA composites stemmed from the good interfacial bonding between the CNPs and PVA matrix. At first, the porous geopolymer was prepared easily, and then, the geopolymer/Fe 3 O 4 nanocomposite was synthesized via the intercalation method (White et al., 2011; This chapter provides the synthesis and chemical properties of porphyrins.
