Abstract

Continuous changes in production techniques of composites have attracted the attention of researchers in the various branches of science, starting from academic research and ending in engineered materials. These techniques aim to preserve their beneficial properties and try to increase their efficiency with the introduction of new standards to this component which may not be already owned or efficient in a few capacities and are intended to be introduced to the composites [1]. One of the most important properties is produces nanomaterials along with the improvement of its physiochemical properties, due to the unique importance in the technology of its applications [2]. TiO2 is a common semiconductor material that is used in this way due to many causes such as it being inexpensive, and nontoxic [3], and its relatively high reactivity and chemical stability under ultraviolet light [4].

Continuous changes in production techniques of composites have attracted the attention of researchers in the various branches of science, starting from academic research and ending in engineered materials
This new carbon-material, consists of Carbon nanotube CNTs, which appeared to have become a reality for science thanks to Iijima [6], and which was a challenge and temptation at the same time due to it being unknown to some extent, it’s amazing physiochemical properties [7], and the variety of types of single-walled carbon nanotubes (SWNTs), few-walled carbon nanotubes (FWCNTs), and multi-walled carbon nanotubes (MWNTs).Many attempts brought together a, high surface area, fascinating electronic, chemical and mechanical properties for CNTs [8] with a low surface area for TiO2, in addition to the properties mentioned above
[13], which may explain the value of the surface area for 0.5% MWNT/ TiO2 (64m2/g), which was more than 0.5% SWNT/TiO2 (54 m2/g) and TiO2(51 m2/g)
