Environmentally friendly polysiloxane and clay/polysiloxane composite coatings were synthesized on aerospace-grade aluminum alloy AA2024-T3 substrates from mildly acidified aqueous solution. The polysiloxane coatings were synthesized by acid-catalyzed hydrolysis and condensation of organosilane coupling agents such as glycidoxypropyltrimethoxysilane (GPTMS) and tetramethoxysilane (TMOS) followed by...
This paper presents the combustion chemical vapor deposition (CCVD) growth and characterization of epitaxial BST films on sapphire. These thin films were used to fabricate phase shifters and tunable filters from 1GHz to 40GHz using planar gap capacitors. A 2:1 tunability was achieved for BST thin films under a DC bias of as low as 10 V and IMD as high as 50dBM can be achieved. Composition has a significant...
