Synergistic effects of Na+-montmorillonite and multi-walled carbon nanotubes on mechanical properties of chitosan film

Influence of intercalation methods in properties of Clay and carbon nanotube and high density polyethylene nanocomposites

“…Wang et al 8 achieved increases of 100% in impact strength and 70% in the Vickers hardness of composites with epoxy / clay / CNT. Zhang and Wang 6 reported increases of 50% in the Young's modulus of the nanocomposites. These authors could observe, by means of x-rays diffraction, possible clay exfoliation states when using the carbon nanotube in the nanocomposites.…”

“…When carbon nanotubes are incorporated, electrically and thermally conductive polymer composites can be produced, and at the same time reinforcement can be obtained 3,4 . Recently, it is possible to find in the literature a route of nanocomposites production which combine clays, carbon nanotubes and polymeric matrices [5][6][7][8][9][10][11][12] . Two different route was observed: 1) carbon nanotubes are synthesized (usually by chemical vapor deposition) on clay surfaces which are subsequently incorporated into polymer matrixes 7,8,11 , 2) clays and carbon nanotubes are incorporated separately into polymer matrixes 5,6,9,10,12 .…”

A pH-, salt- and solvent-responsive carboxymethylcellulose-g-poly(sodium acrylate)/medical stone superabsorbent composite with enhanced swelling and responsive properties

“…The buffer solutions with various pH values were prepared by combining KH 2 PO 4 , K 2 HPO 4 , H 3 PO 4 and NaOH solution properly and the pH values were determined by a pH meter (DELTA-320). Ionic strengths of all the buffer solutions were controlled to 0.1 M using NaCl.…”

“…Medical stone (MS) is a special clay mineral that is different from other clays in both structure and properties. MS is an igneous rock composed of silicic acid, aluminum oxide and above 50 kinds of constant and trace elements, and so it was known as 'health-stone' [28] 4 ] configuration, and has a three-dimensional stereo-structure in which aluminum coordinates through oxo-bridging. MS has excellent porosity, multicomponent characteristic, biological activity and safety, and so it shows excellent surface activities, and has been extensively applied in food science, medicine, daily chemical industry, environmental sanitation and wastewater treatment, etc.…”

Influence of mixing in mechanical properties of clay and carbon nanotube and high density polyethylene

“…When carbon nanotubes are incorporated electrically and thermally conductivite polymer composites can be produced, and at the same time reinforcement can be obtained [3,4]. Recently, it is possible to find in the literature a "new route" of nanocomposites production which combine clays, carbon nanotubes and polymeric matrices [5][6][7][8]. Ma et al [8] found experimentally that there is a strong synergistic effect when carbon nanotubes and nanoclay was mixed simultaneous in an ABS matrix.…”
