Abstract Carbon nanotubes (CNTs), with unique graphitic structure, superior mechanical, electrical, optical and biological properties, has attracted more and more interests in biomedical applications, including gene/drug delivery, bioimaging, biosensor and tissue engineering. In this review, we focus on the role of CNTs and their polymeric composites in tissue engineering applications, with emphasis on their usages in the nerve, cardiac and bone tissue regenerations. The intrinsic natures of CNTs including their physical and chemical properties are first introduced, explaining the structure effects on CNTs electrical conductivity and various functionalization of CNTs to improve their hydrophobic characteristics. Biosafety issues of CNTs are also discussed in detail including the potential reasons to induce the toxicity and their potential strategies to minimise the toxicity effects. Several processing strategies including solution-based processing, polymerization, melt-based processing and grafting methods are presented to show the 2D/3D construct formations using the polymeric composite containing CNTs. For the sake of improving mechanical, electrical and biological properties and minimising the potential toxicity effects, recent advances using polymer/CNT composite the tissue engineering applications are displayed and they are mainly used in the neural tissue (to improve electrical conductivity and biological properties), cardiac tissue (to improve electrical, elastic properties and biological properties) and bone tissue (to improve mechanical properties and biological properties). Current limitations of CNTs in the tissue engineering are discussed and the corresponded future prospective are also provided. Overall, this review indicates that CNTs are promising “next-generation” materials for future biomedical applications.

We prepared the polyaniline@polypyrrole (PAn@PPy) conductive composite by a novel method. The struction like Pre-prepared PAn as the core and PPy as the shell for the composite has been prepared by in-situ polymerization. The PAn@PPy conductive composite presents an electrical conductivity of 12.5 S/cm, which is much higher than pure PAn. The synthesized polymer composites are characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Thermogravimetric analysis (TG). The results indicated that PPy successfully grafted on PAn and the heat resistance of nanocomposite is remarkably increased.

Zirconia Cermet

A novel method was studied for producing a ceramic-metal matrix composite (cermet) of Mo metal and zirconia powder. The first step was to precipitate dissolved molybdenum from solution onto activated zirconia powder. The molybdenum plated out on the zirconia as molybdenum hydroxide. Next, the coated powders were heated in a tube furnace under hydrogen gas to reduce the molybdenum hydroxide to metallic molybdenum. Finally, the powders were pressed and sintered into cermet pellets. The Mo coatings were 1.5 to 4.2 μm thick and very uniform, enabling the particles to be sintered together. The sintered pellets had superb electrical conductivity (less than 1 ohm of resistance).

The reaction takes place with the in situ polymerization of EDOT within the framework of crystallineV2O5with different nominal EDOT/V2O5ratios. The hybrids PEDOT/V2O5exhibit a high electrical conductivity
