Optical Fibers with Polyimide Coatings for Medical Applications
Key properties of polyimide-coated optical fibers, unaged and exposed to various harsh environments, were investigated. The main intent was to model extreme conditions that can be encountered in medical applications of the fibers. A fiber designed by OFS showed good strength and was able to withstand exposure to extreme heat and humidity, multiple autoclave cycles, extended water soak and immer...
متن کاملPreparation of Palladium/Silver-Coated Polyimide Nanotubes: Flexible, Electrically Conductive Fibers
A simple and practical method for coating palladium/silver nanoparticles on polyimide (PI) nanotubes is developed. The key steps involved in the process are silver ion exchange/reduction and displacement reactions between silver and palladium ions. With the addition of silver, the conductivity of the PI nanotubes is greatly enhanced. Further, the polyimide nanotubes with a dense, homogeneous co...

متن کاملAnisotropic conductive films based on highly aligned polyimide fibers containing hybrid materials of graphene nanoribbons and carbon nanotubes.
Anisotropic electrically conductive films (PI-GNR/CNT) consisting of highly aligned polyimide (PI) composite fibers with graphene nanoribbon (GNR) and carbon nanotube (CNT) (GNR/CNT) hybrids as nanofillers have been prepared by electrospinning. The GNR/CNT hybrids used here were prepared by one-step partial unzipping of multi-walled CNTs, in which, with the residual CNTs bonded on the randomly ...
متن کاملPolyimide-matrix Chemical-selective Membranes
Preliminary work using polyimide (PI) as the polymer matrix for permselective membranes is reported in this paper. The excellent adhesion of polyimide may be helpful in extending solid-state chemical sensor lifetimes. Electrochemical performance and adhesion to S&N, of these membranes is compared to that of conventional PVC-based membranes.
