Polyimide

Polyimide-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.

Biosensors Using Micromachined Polyimide Probes

This paper explores the electrochemical patterning of thin metal films using a scanning probe tip as an electrode. In particular, a masking nickel film is etched to reveal a gold pattern to which biomolecules like liposomes and proteins can be attached after treatment with functionalized self assembled monolayers (SAMs) of gold-thiolate. The machining is performed by ultracomplaint polyimide mi...

Polyimide/Carbon Nanotube Composite Films

Low color, space environmentally durable polymeric films with sufficient electrical conductivity to mitigate electrostatic charge (ESC) build-up have potential applications on large, deployable, ultra-light weight Gossamer spacecraft as thin film membranes on antennas, solar sails, thermal/optical coatings, multi-layer insulation blankets, etc.. The challenge has been to develop a method to imp...

Wet anisotropic etching of polyimide

With the aim of developing flexible biocompatible implants for in vivo studies of nerve regeneration [1], fabrication of passive polyimide membranes using the commercial available Kapton film (100HN and 50HN, from DuPont) was investigated. Polyimide has been widely used in microelectronics, and its application possibilities have been widening to other fields such as micromachining and biomedica...
