The improvement of thin polymer film properties through plasma immersion ion implantation and deposition technique
Thin polymer films were deposited from acetylene and argon mixtures by plasma immersion ion implantation and deposition. The effect of the pulse frequency, v, on molecular structure, optical gap, contact angle and hardness ...
Crystallization and optical properties of CCTO thin films under pressure influence
CCTO thin films were deposited on Pt(111)/Ti/SiO 2/Si substrates using a chemical (polymeric precursor) and pressure method. The pressure effects on the CCTO thin films were evaluated by XRD, FEG-SEM and optical properties. ...
Polymer-based nanocomposites: In situ generation and immobilization of gold nanoparticles on poly(n-vinyl-2-pyrrolidone) and poly(ϵ-caprolactone) thin films
(American Scientific Publishers, 2017)
Copyright © 2017 American Scientific Publishers All rights reserved. In this work, we report an interesting method for simultaneous obtaining and immobilization of gold nanoparticles onto polymer thin films. Polymer-based ...
Catalytic EC reaction at a thin film modified electrode
Numerical simulations of cyclic voltammograms corresponding to a catalytic EC reaction taking place at a thin film modified electrode are performed by way of finite difference method. Besides considering the chemical ...
The metal/electroactive polymer interface studied by surface resistance
(Scientific Research, 2013-07)
The experimental arrangement in this investigation was one in which a poly(o-aminophenol) (POAP) film was sup- ported on a thin gold film electrode whose thickness is of the order of the mean free path of conduction electrons ...
Preparation and characterization of SrBi2Nb2O9 thin films made by polymeric precursors
A polymeric precursor solution was employed in preparing SrBi2Nb2O9 (SBN) powder and thin films dip coated onto Si(100) substrate. XRD results show that the SBN perovskite phase forms at temperatures as low as 600°C through ...
Spectral redistribution of waveguided emission in BEH-PPV films
(Taylor & Francis Ltd, 2002-01-01)
We report on spectral redistribution of the photoluminescence (PL) emission from the edge of thin-film planar waveguides of the conjugated polymer BEH-PPV [Poly(2,5-bis(2'-ethyl-hexyl)-1,4-phenylenevinylene] induced by ...
Plasma enhanced chemical vapor deposition of titanium(IV) ethoxide-oxygen-helium mixtures
