Abstract

Although the area involving the application of polymeric hydrogels is rapidly maturing, little is reported about the preparation and response of discrete hydrogels within a hydrophobic coating matrix. It will be the objective of this research to determine how the structural variations in gels, both chemical and mechanical, will affect water absorption. In an effort to better understand this area, film preparation methods along with the composition and properties of both the hydrogels and continuous phase will be investigated. This investigation will be carried out by looking at film properties firstly and then follow with an examination of the responsiveness of the film to various external stimuli. These characteristics can then be related to the morphology and theological properties of these films and their components. This developed technology can be used to further the research and development currently being conducted for application of hydrogels as separation systems, as active delivery materials, as actuators, and as biomimetic devices.
