“…[31][32][33] The MWCNTs used as reinforcement consist of layers of hexagonal graphene sheets rolled into seamless cylinders forming coaxial layers. [34] There are several synthesis methods of MWCNTs like Catalytic Chemical Vapor Deposition (CCVD), [35][36][37] laser ablation [36,[38][39][40] and arc discharge [36,[39][40][41] methods.…”

Effect of sonication time on the synthesis of the CdS nanoparticles within the matrix obtained through the covalent functionalization of multiwall carbon nanotube (MWCNT) with maleic anhydride (MA)-1-octene copolymer was investigated. Cadmium chloride and thiourea were used as the raw materials. MWCNTs used for the matrix were synthesized by Catalytic Chemical Vapor Deposition using Fe-Co/Al 2 O 3 as the catalyst. The obtained nanostructures were characterized by FTIR, XRD, Raman spectroscopy, TEM, SEM, TG and UV-Vis spectroscopy. Electrophysical properties of the polymer nanocomposites obtained using different periods of time for sonication were comparably investigated. The average CdS particle diameter was between 3.9-7.9 nm as confirmed independently by TEM and XRD. UV-Vis spectroscopy revealed that the obtained nanostructures are appropriate base materials for making optical devices.

“…In the past few decades, carbon nanotubes (CNTs) have received intense research interests because of their desirable mechanical, optical, electrical and thermal properties [1]. In general, methane [2][3][4], ethylene [5][6][7][8], acetylene [4,[9][10][11] and other hydrocarbons have been used as carbon sources for CNT synthesis. Apart from these hydrocarbons, the use of waste polymers feedstock is more environmental and economical feedstock for CNT synthesis, hence transforming waste polymers into high value-added CNTs is desirable.…”

NiO catalyst supported on Fe-pillared montmorillonite (5-15 wt% Ni) was prepared via a simple conventional impregnation method. The physicochemical properties of the Ni catalyst were characterised by X-ray diffraction, inductively coupled plasma-atomic emission spectrometry and transmission electron microscopy. The Ni catalyst, together with organic montmorillonite (OMMT), was employed to prepare multi-walled carbon nanotubes (MWCNTs) by using polypropylene (PP) as a precursor. An increase in Ni loading of the catalyst led to a significant increase in the yield of MWCNTs at the expense of a slight decline in quality of the obtained MWCNTs. Moreover, OMMT altered the degradation process of PP, which resulted in a much higher fraction of light hydrocarbons in degradation products. As such, a substantial increase in the yield of MWCNTs was attained. In addition, the obtained MWCNTs were used as flame retardant for PP, and significantly enhanced thermal stability and flame retardancy according to thermogravimetry analysis and cone data, respectively. PP/MWCNTs nanocomposite exhibited higher degradation temperature, longer ignition time, much lower heat release rate and smoke production rate. This work offers an efficient Ni catalyst to convert PP into MWCNTs which could be applied as flame retardant for polymers.
