We report on our systematic and detailed study of fabrication and characterization of polyaniline (PA) prepared by vacuum deposition and polystyrene (PS) prepared by dip coating method thin film optical waveguides. The four-layer consisting of substrate (glass)/PA/PS/air has been used for demonstrating polarization filter action.

Electrochromic WO3 thin film was prepared by using tungsten metal solution in hydrogen peroxide as a starting solution and by sol-gel dip coating method. XRD pattern showed that tungsten oxide crystal phase formed at 400. In the view of electrochemical property, WO3 thin film which was heat-treated at 300 and was amorphous had better than that of the crystalline phase.

ZnO:Eu3+ films were obtained by dip-coating method and influence of heat treatment on luminescent properties was investigated. Emission and excitation spectra revealed that the organic and nitrate molecules, which adhered on the surface of films when the samples were treated at lower temperatures (300oC-400oC), played an important role on the luminescent properties. At higher temperatures (500oC-800oC), the luminescence spectra of ZnO and Eu3+ were quite different with those treated at lower temperatures. Energy transferred from ZnO host to Eu3+ was obviously observed in the emission and excitation spectra. The luminescence mechanism was discussed briefly.

A biodegradable chitosan-acetate microneedle is developed based on the proboscis of a mosquito, which consists of chitin and protein. The formability of chitosan, which is a deacetylated compound of chitin, is improved by dissolving it in dilute acetic acid. Thereafter, the dissolved chitosan is coated around an Al wire by a dip-coating method, followed by drying. Afterward, the Al wire is removed by etching using an alkaline solution to form the chitosan micropipe. Subsequently, the micropipe is baked at 200°C for 0.20 min. The optimum baking time was found to be 17 min. Finally, the micropipe is cut and its tip sharpened to transform it into a microneedle with a length, an outer diameter, and an inner diameter of 4 mm, 150 μm, and 100 μm, respectively. The Young’s modulus of the fabricated chitosan microneedle is approximately 10 GPa. This microneedle could be inserted into an artificial skin made of silicone rubber without buckling, and it could aspirate blood from a frog at a rate of 2.5 μL/s.

A study has been conducted on the characterization of optical properties of thin films from lidah mertua (Sansevieria trifasciata) with dip coating method. The dip coating method was applied with different temperature and different time immersion treatments. The measuring variables in the manufacture of this thin film were tested based on the optical properties of their absorbance value of the extract and the thicknessof thin film. The absorbance spectral of extraction pigments were measured using UV-Vis in the wavelength range 350 nm to 700 nm. The results of the measurements showed that the extract of the S. trifasciata has high absorbance. Beside that, the minimum coating thickness is produced by a concentration of 12.5% with a 5 minute immersion time of 520 nm.
