In Situ Monitoring of Coating Polymerization,Cure and Aging Using Frequency Dependent Dielectric Monitoring

摘要

Frequency dependent dielectric measurements using in situ micro sensors,FDEMs,is a particularly useful technique for monitoring the changing state of a coating during synthesis,cure,and aging.Measurements can be made in the laboratory to monitor the polymerization process in a flask,to monitor cure in an oven or under a UV lamp,and to monitor durability and aging in a weather controlled environmental chamber or other degradative environment.
