Abstract

Development of nanomaterial technology strongly supports advancements in composite technology. Composite that use nanomaterial produce better electrical properties than common composite. Carbon nanotubes (CNT) is one of nanomaterial with high conductivity, so it’s potentially used in composite for various aplication. This research combines Carbon Nanotubes (CNT) with Polyvynilidene Flouride (PVDF) for producing CNT-PVDF composite with high conductivity. CNT-PVDF composites were fabricated by solution processing method. PVDF was dissolved into distillated aceton then CNT was dissolved in acetone and added Triton X-100 4 ml. PVDF solution and the solution of CNT were stirred for 1 hour using a magnetic stirrer, then both were mixed and stirred at temperature of 40 ° C until the acetone evaporates. Composites were molded using a hot-pressing at a pressure of 1 MPa and a temperature of 200oC for 10 minutes. CNT-PVDF composite were characterized by a conductivity test to generate conductivity values​​. The results of the analysis of the test showed that the addition of CNT conductivity on CNT-PVDF composite increased conductivity values​​. In the mass percentage of CNT 2%, 4%, 6%, and 8% conductivity increased slowly. Improved high conductivity of CNTs obtained in the mass percentage of 10%.

Abstract

Nanocomposite thin film of TiO2/CNT as a photocatalyst material was  synthesized using the sol-gel method with the dispersion of commercial TiO2 Merck in CNT. The crystal structure and nanocomposite thin film morfology of TiO2/CNT were characterized using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Sol TiO2 0.3 M was mixed into the sol CNT with mass ratio of CNT:TiO2 was 1:5. Sol TiO2/CNT was sprayed on a glass substrate that was  heated at a temperature of 250 oC, then it was heated at the temperature of 450 °C for 60 minutes. Photodegradation was done by dipping the nanocomposite thin film of TiO2/CNT into 100 mL Azo Orange 3R dye sol 10 ppm, then was irradiated using UV light with a wavelength 380 nm. XRD pattern analysis showed that TiO2 has anatase structure with crystallite size at the range from 72-92 nm by using Scherrer equation. SEM image analysis showed that the grains of TiO2 sfreris pattern and was dispersed on CNT. Refluks TiO2/CNT nanocomposite thin film had been able to degrade Azo Orange 3R dye sol for 12 hours until percentage of 98,2% which was much better than the non reflux TiO2/CNT nanocomposite thin film as 97,2% and the TiO2 thin film as 90,9%. Keywords : TiO2, carbon nanotubes, thin film, nanocomposite, photodegradation, Azo Orange 3R dye.

Abstract

The electrodes are made of a combination between the CNT and the activated carbon had been created as a method of desalination systems the flow-through capacitor (FTC). The FTC  is one method desalination done by flowing salt water passed the between electrodes based on the principle capacitor. The addition of the CNT on activated carbon as electrode will hopefully increase the conductivity and resistivity on activated carbon reduces that provides increased absorption. System optimization testing FTC desalination is carried out by the time of voltage and variation flow rate solution.Fabrication of electrodes are made of mixed a primary ingredient CNT to the activated carbon with a comparison of 10:90 (% wt) and urotropin to the phenolic resin Binder ratio10:90 (% wt). Comparison of carbon : fastener end of 80:20. The electrodes are formed with method of hot-pressing and heated for 30 minutes at a temperature of 1800C . The electrodes are  resistance tested and characterized using SEM to saw the shape of the morphology of the electrodes.Prototype tested results with 7 pairs of electrodes 10% CNT could separated a compound salt of solution 1785 mg/L during 120 minutes with a flow rate 5 mL/min of 57%. Tested by conduktivitimeter at flow rate variation 5, 15, 25, and 35 mL/min had the lowest concentration of the solution on the reduction in flow rate 5 mL/min. But the solution that had passed through the electrodes on the low flow are much less than with a high flow rate.Keywords : Electrodes, desalination, FTC, CNT, activated carbon.
