- 2018Decolourisation of reactive black-5 at an RVC substrate decorated with PbO2/TiO2 nanosheets prepared by anodic electrodeposition ; Reticulated vitreous carbon (RVC) substrates were coated with a composite of PbO2 and titanate nanosheets (TiNS) by anodic electrophoretic depostion. The structure and morphological characteristics of the coating were evaluated by field emission scanning electron microscopy (FESEM) and Raman spectroscopy. The TiNS/PbO2/RVC coating contained the anatase phase and showed a well-defined, microporous morphology with hydrophilic character along the length and thickness of the RVC struts. Electrochemical and photocatalytic activity of the coatings facilitated RB-5 dye degradation as a model organic pollutant in wastewater. The electrochemical decolourisation involves the generation of hydroxyl free radicals over the TiNS/PbO2/RVC anode composite surface, whereas photocatalytic decolourisation was driven by the synergetic photocatalytic effect imparted by the photoinduced holes and free electron acceptors. The photocatalytic properties of the TiNS/PbO2 coating were achieved by calcination at 450 °C for 60 min in air which converted the titanate phase to anatase and modified its surface area. This enabled 98% electrochemical decolourisation of the RB-5 dye solution (measured by visible absorption at 597 nm) in a time of 60 min.citations
- 2017Titanate nanotubes and nanosheets as a mechanical reinforcement of water-soluble polyamic acid: Experimental and theoretical studies ; Titanate nanosheets (TiNS), titanate nanotubes (TiNT), and scrolled titanate nanosheets (STiNS) were used to synthesise polymer nanocomposites by solution processing. The hardness was found to increase by 90% on addition of 2% TiNS while the modulus (Er) increased by 103% compared to the pure polymer. Small angle X-ray scattering (SAXS) measurements of composite films were used to study alignment of nanostructures within the polymer. The obtained data on mechanical properties of composites have been tested against theoretical values and it was established that both nanostructures alignment as well as their mechanical properties affect the hardness and modulus of the polymer composites. At a low content of TiNS, the reinforcement behaviour matched well with Halpin-Tsai theory which assumes the filler has unidirectional orientation. After addition of 2 wt% TiNT, the hardness and modulus of the polyamic acid salt composites increased by 91% and 165%, respectively, and were higher than theoretical predictions, indicating that both TiNT and STiNS, prepared by hydrothermal synthesis, may have higher mechanical properties than bulk TiO2. At a high filler loading (>2 wt%), the mechanical properties of composites do not fit established theories due to agglomeration of titanate nanostructures.citations

- 2015Effect of Amide Functionalization and Precuring on Tensile Properties of MWCNT/Epoxy Nanocomposites ; SummaryThe development of multi‐walled carbon nanotube (MWCNT)‐epoxy nanocomposites, for structural polymeric composites, has various problems that could decrease their mechanical properties above 2 wt % of MWCNT. One of the major problems is the interface bonding between MWCNT and epoxy. In this research, functionalization and precuring were carried out to strengthen the interface bonding. The effect of treatments on tensile properties of MWCNT‐epoxy nanocomposites, with 1 wt% and 5 wt% MWCNT, were studied. MWCNT were prepared by purification process followed by acrylamide functionalization, later varied by the precuring treatment. MWCNT‐epoxy nanocomposites, varied from 1 to 5 wt% MWCNT, were produced by solution casting method, continued with compression molding. Characterization of the functionalization was conducted by Fourier Transform Infrared Spectroscopy (FTIR). The tensile properties of nanocomposites were determined by tensile test. Scanning Electron Microscope (SEM) was used to examine the interfacial strength of MWCNT in nanocomposites. The results showed that the tensile properties improved significantly on 5 wt % MWCNT nanocomposites as compared to the untreated nanocomposites. The combination of functionalization and precuring exhibited the most significant improvement in tensile properties. The modulus of elasticity increased 78 times higher than untreated nanocomposites, while the tensile strength was 10 times. The improvements on the tensile properties of nanocomposites were due to the enhancement of interface bonding strength by functionalization and precuring treatments.citations
