What is diffusion coefficient in polyimid?
The diffusion coefficient in polyimide refers to a measure of how quickly molecules or ions can move through the polymer matrix. It is influenced by factors such as temperature, molecular size, and the polymer's physical structure. A higher diffusion coefficient indicates faster transport of species within the polymer, which can significantly impact the material's performance in applications like membranes or coatings. Understanding this parameter is crucial for optimizing polyimide materials for specific uses, particularly in electronics and aerospace industries.

Write an example for thermosetting plastic and thermo plastic?
Thermoplastics can be repeatedly softened by heating and hardened by cooling. Thermosetting plastics, however, harden permanently after being heated once. An example of thermoplastic is polypropylene (PP - recycling number 5). An example of thermosetting plastic is polyurathane (PU).

Why the satellites are covered with gold foils?
Firstly its not gold that is being used, Satellites(nowadays) are covered with Metallized kapton polyimide film.Generally it is something called MLI (multi-layer insulation, aka thermal blanket)these are made up of many layers of aluminized polyimide. Polyimide is a type of plastic, and yellow in color. It's coated with aluminum on the inside surface so it looks gold. Bare aluminum reflects radiation very well, which means it absorbs heat very slowly. But it also radiates heat VERY slowly. An aluminum foil sitting in vacuum in direct sunlight will heat up to a pretty high temperature. Plastic film with aluminum backing absorbs heat a little faster, but it also radiates heat a lot faster, so it works better as the outer-most layer of the MLI.
