Thin films of polyazulene (PAz) are produced by using an optimized atmospheric pressure–vapor phase polymerization (AP-VPP) method. Method optimization is carried out studying the effect cell temperature, substrate time, and washing-solvent on film properties like optical bandgap, sheet resistance, surface roughness, % transmittance (%T). Multi-layered PAz were layer-by-layer engineering. The e...

Conductive core-sheath TiO(2)-PEDOT nanocables were prepared using electrospun TiO(2) nanofibers as template, followed by vapor phase polymerization of EDOT. Various techniques were employed to characterize the sample. The results reveal that the TiO(2) core has an average diameter of ∼78 nm while the PEDOT sheath has a uniform thickness of ∼6 nm. The as-prepared TiO(2)-PEDOT nanocables display...

BACKGROUND Highly hydrophobic surfaces can have very low surface energy and such low surface energy biological interfaces can be obtained using fluorinated coatings on surfaces. Deposition of biocompatible organic films on solid-state surfaces is attained with techniques like plasma polymerization, biomineralization and chemical vapor deposition. All these require special equipment or harsh che...

We describe herein the construction of simple, low-power, broadly responsive vapor sensors. Insulating polymer-conductor composites have been shown to swell reversibly upon exposure to vapors. Thin films of polymer composites have been deposited across two metallic leads, with swelling-induced resistance changes of the films signaling the presence of vapors. To identify and classify vapors, arr...

in this work, the interfacial interfacial polymerization (ip) technique was employed using terephthaloyl chloride (tpc) and p-phenylenediamine (ppd), as reactant monomers, to prepare poly(paraphenylene terephthalamide) thin film composite (tfc) nanofiltration on polyethersulphone (pes) support layer. the effects of six different anionic and non-ionic surfactants, in the aqueous phase on the mor...
