Review article: Hybrid materials based on carbon nanotubes

Carbon nanotubes-based hybrid and composite materials, recently, are a hot topic in research about advanced materials. Nanotubes are functionalized and hybridized with both organic and inorganic compounds for designed applications. Hybrid materials can be fabricated by direct or in-direct method. Some investigations about electrical, optical and photocatalytic properties of hybrid materials would be discussed. | Journal of Science and Technology 54 (5A) (2016) 159-168 REVIEW ARTICLE: HYBRID MATERIALS BASED ON CARBON NANOTUBES Nguyen Cong Tu*, Nguyen Huu Lam School of Engineering Physics, Hanoi University of Science and Technology, No 1, Dai Co Viet street, Ha Noi * Email: tu.nguyencong@hust.edu.vn Received: 15 July 2016; Accepted for publication: 4 December 2016 ABSTRACT Carbon nanotubes-based hybrid and composite materials, recently, are a hot topic in research about advanced materials. Nanotubes are functionalized and hybridized with both organic and inorganic compounds for designed applications. Hybrid materials can be fabricated by direct or in-direct method. Some investigations about electrical, optical and photocatalytic properties of hybrid materials would be discussed. Keywords: CNT, hybrid material, metal oxide semiconductor. 1. INTRODUCTION Since discovered by Iijima in 1991 [1], carbon nanotubes (CNTs), due to its outstanding electrical, mechanical properties, are one of the most attractive nanostructure materials in recent decades. Because of the limit of technology, CNT-based electronic devices, however, is only fabricated and tested in laboratory. To make the most of CNTs’ outstanding properties for real applications, recently, researchers have given lot efforts to study CNT-based hybrid materials for real applications such as energy storage, supercapacitor, biosensor, gas sensor, cooling material [2 - 20]. The CNTs-based hybrid material, for a designed application, was synthesized by corresponding method with the suitable functional material. This paper will give an overview of recent reports on developing CNTs-based hybrid materials. 2. CNT-BASED HYBRID MATERIALS 2.1. CNT-based hybrid materials: recent researches and potential applications In studying about hybrid materials, researchers hope to combine the advantages of different components and widen the potential applications of materials. CNTs walls are inert with chemical reaction, so it is very .
