Polyimide materials are lightweight, flexible, resistant to heat and chemicals. Therefore, they are used in the electronics industry for flexible cables and as an insulating film on magnet wire. For example, in a laptop computer, the cable that connects the main logic board to the display (which must flex every time the laptop is opened or closed) is often a polyimide base with copper conductors. … WebPOLYIMIDES: chemistry & structure-property relationships – literature review 1.1 Introduction Polyimides are a class of thermally stable polymers that are often based on stiff aromatic backbones. The chemistry of polyimides is in itself a vast area with a large variety of monomers available and several methodologies available for synthesis.

WebThe polyimide was brought to room temperature overnight in its sealed container. A small amount (approximately 20 ml) of the polyimide was then poured into a 50-ml glass beaker, and the beaker was placed into a Scienceware Mini Vacuum Desiccator (figure 2). A vacuum was pulled, and the polyimide was degassed for several hours just prior to using. WebPolyimide starts as an imide-containing polymer molecule.
