“…In general, the surface roughness of P3HT thin film coatings should not exceed ca. 10 nm for most optoelectronic applications (Truong et al, 2008), which was satisfied in this study. Fig.…”

“…After sonicating the catalyst solution for 2 minutes at 40ºC, it was spin-coated onto the substrates at a speed of 500 rpm for 5 seconds and then at 1400 rpm for 5 seconds. Subsequently, the catalyzed substrates were placed in the vapor-phase-polymerization (VPP) chamber containing 3-hexylthiophene (3HT) monomer to evaporate and fill therein under a nitrogen purge, which is similar to that reported elsewhere (Truong et al, 2008). The 3HT monomers in the VPP chamber were polymerized for one hour at 50ºC.…”

“…The surface morphology is important when P3HT is used for thin coating applications because it influences a large number of properties, such as double layer capacitance and adhesion (Truong et al, 2008). It was reported that the polymerization rate of conjugated polymers, surface treatment and Fe(III) solution removal conditions substantially affect the surface morphology of thin film coatings (Truong et al, 2008) and monomers successfully in order to make the surfaces of thin conducting polymers smoother.…”

“…PEDOT is known as a transparent conducting polymer and is widely used as an interfacial layer or polymer electrode in polymer electronic devices [30][31][32][33]. When a thin dielectric elastomer sheet is confined by rigid boundaries, the applied compressive force causes the material expansion.…”

Dielectric elastomers with low elastic stiffness and high dielectric constant are smart materials that produce large strains (up to 300%) and belong to the group of electroactive polymers. Dielectric elastomer actuators are made from films of dielectric elastomers coated on both sides with compliant electrode material. Poly(3,4-ethylenedioxythiophene) (PEDOT), which is known as a transparent conducting polymer, has been widely used as an interfacial layer or polymer electrode in polymer electronic devices. In this study, we propose the transparent dielectric elastomer as a material of actuator driving variable-focus lens system using PEDOT as a transparent electrode. The variable-focus lens module has light transmittance up to 70% and maximum displacement up to 450. When voltage is applied to the fabricated lens module, optical focal length is changed. We anticipate our research to be a starting point for new model of variable-focus lens system. This system could find applications in portable devices, such as digital cameras, camcorder, and cell phones.

The co‐vaporization and simultaneous polymerization of EDOT and APTES on a FTS‐coated substrate resulting in a homogeneous PEDOT/ASSQ thin film is described. The physicochemical properties of the film, including surface hardness, solvent mechanical wear resistance, and resistance to scratch, were much better than those of pure PEDOT. A PEDOT/ASSQ hybrid film with homogeneous morphology resulted, as judged by AFM topography scans, surface roughness calculations, and SEM images. The ASSQ proportion in the hybrid films, as investigated by XPS and EDS, was strongly dependent on the content of FTS on the substrate. In addition, the simultaneous polymerization of a PEDOT/ASSQ hybrid film onto selective micropatterns was demonstrated and analyzed. magnified image
