Poly(ester-imide)s (PEI)s are a kind of non-vinyl polymers which can be prepared via step-growth polymerization. They contain ester and imide linkages in the polymer backbones and lately show significant applications, such as adhesives, printed circuit boards, membranes, and engineering thermoplastics. Synthesis of chiral polymers is an important field in macromolecular science, they have attracted...
In this work are discussed the technology for preparing and characterisation of indium-tin oxide (ITO) and ITO with titanium oxide underlayer thin films with properties appropriate for usage at elevated temperatures as heat reflective coatings and gas sensors. For preparing the samples the methods of radio frequency (RF) and DC-magnetron reactive sputtering were used. Sputtering of indium-tin and...
Multilayer oxide thin film stacks of aluminum doped zinc oxide (AZO) and tin doped indium oxide (ITO) have been sequentially deposited on soda lime glass substrates by RF sputtering of AZO and ITO ceramic targets at a substrate temperature of 150??C. The ratio of the AZO thickness to the ITO thickness is varied while keeping the total thickness of the stack constant. The electrical and optical properties...
The influences of bismuth (Bi) on the microstructure and ferroelectricity of Sr0.5Ba0.5-xBixTiO 3 (BST) thin films were studied. The Pr, Ps and Ec was 0.22muC/cm2, 0.72muC/cm2 and 60 Kv/cm respectively for Sr0.5Ba0.485Bi0.015TiO 3 thin film at 100 Hz, 20V. The microstructure and phase analyses of BST thin films were examined by XRD, FTIR and TEM. The results show that tetragonal perovskite crystal...
The effect of plasma assistance during vacuum evaporation was investigated. Silicon films were deposited by e-beam evaporation on Bright Annealed AISI 304 stainless steel and on soda-lime glass substrates at 225/spl deg/C, under 2.28/spl times/10/sup -3/ mbar and e-beam power of 720 W. A low voltage arc was used as a plasma source for ion plating, with argon and argon/hydrogen atmosphere. Structural...
