“…Increasing the loading of inorganic metal hydroxides will result in a significant decrease in physical properties. So synthesis of Al(OH) 3 nanostructures has attracted much attention in recent years owing to their unique properties and wide applications in plastics, rubbers, papers, glasses and medicines, and so forth [6][7][8][9][10][11]. In addition aluminum hydroxide is an important precursor for synthesis of alumina and alumina-derived ceramics.…”

Applying of the most toxic halogenated and aromatic flame retardants is limited with respect to the environmental requirements. Nontoxic Al(OH) 3 nanoparticles were synthesized via a simple surfactant-free precipitation reaction at room temperature. The effect of various precipitation-agents on the morphology of the products was investigated. Al(OH) 3 nanoparticles were added to the polysulfone and poly styrene (PS) matrices. Electron microscope images show excellent dispersion of aluminium hydroxide in PS matrix. Nanoparticles appropriately enhanced both thermal stability and flame retardant property of the polymeric matrices. The enhancement of flame retardancy is due to endothermic decomposition of Al(OH) 3 that absorbs heat and simultaneously releases of water (makes combustible gases diluted and cold). Dispersed nanoparticles play the role of a barrier layer against flame, oxygen and polymer volatilization. Al(OH) 3 was converted to Al 2 O 3 and its photo-catalyst property in degradation three different organic dyes as pollutants was investigated.

“…The sample is classified V-2 if it has the combustion time criteria of V-1, but flaming drips are allowed. Samples are ranked as N.C. in UL-94 tests when the maximum total flaming time is above 50 s. The sample is classified HB when slow burning on a horizontal specimen; burning rate \76 mm/min [5,17,18]. Nanofibers were prepared by a instrument made by Asian Nanostructures Technology Company.…”

“…The principal profits of nanocomposites over many metallic alloys are corrosion resistance, low density and thermal insulation. However the main disadvantage of polymeric compounds is high flammability [15][16][17][18].We report precipitation synthesis of Ag nanoparticles, and nano-flowers via simple chemical reactions without using inert atmosphere and microwave synthesis of CaFe 2 O 4 . Nanofibers of pure cellulose acetate and CA-Ag-CaFe 2 O 4 nanocomposite were prepared by eletro-spinning at different voltages and distances.…”

Calcium ferrite nanoparticles were synthesized by a rapid microwave method and silver nano-flowers were synthesized via a simple chemical reaction without using inert atmosphere at room temperature. Cellulose acetate (CA) nanofibers and their nanocomposites with Ag and CaFe 2 O 4 were prepared by electro-spinning method. Effect of various electric potentials and distance on the morphology and diameter of fibers were investigated. Photocatalytic property of silver in degradation four different azo-dyes as pollutants in water was investigated. CaFe 2 O 4 nanoparticles exhibit a ferrimagnetic behavior at room temperature. Nontoxic nanoparticles appropriately enhanced both thermal stability and flame retardant property of the CA matrix. Also by distribution of CaFe 2 O 4 into CA coercivity was increased.

In this work spherical SiO 2 nanoparticles were synthesized by sonochemical method using a new Schiff-base as a capping agent. The silica nanoparticles were obtained by hydrolysis of tetraethyl orthosilicate in aqueous alcohol solution. The effect of different parameters such as molar concentration of Schiffbase ligands and ultrasonic irradiation on the morphology and size of the products was examined. The results demonstrated that applying the appropriate amount of Schiff-base could be effective in control of particle size. The influence of SiO 2 nanostructures on the flame retardancy of the poly styrene, poly vinyl alcohol, cellulose acetate and ethyl cellulose was studied. In-situ and ex situ nanocomposites were investigated and results confirm that flame retardancy of in situ nanocomposites were better than ex situ samples. HOÁÁÁSi-O-SiÁÁÁOH barrier prevents reaching of flame, heat and oxygen to the polymeric nanocomposites.
