| Summary |
"Corrosion is a phenomenon which has been the subject of extensive research, in order to find a way to control or completely stop it. Two general methods, either placing the material which corrodes in an anti-corrosive atmosphere or protecting the material which corrodes from the corrosive atmosphere, are the chief means of preventing corrosion today. The second method is probably most widely used presently. One of the most important methods of protection is by means of organic protective coatings, or paints, but at best these only retard corrosion, due to the fact that corrosive media e.g. water vapor, ions etc. permeate through the paint film, causing corrosion which eventually destroys it. If a method could be found whereby the permeation of the corrosive media could be blocked, then these protective coatings should last for a considerably longer time. In this thesis it is intended to show what effect, if any, different degrees of crystallinity in poly (ethylene terephthalate) have upon the blocking of certain ions and water which are known to cause and increase corrosion"--Abstract, leaf 1. |
