Structure, Morphology, Property Relationships in Polyisobutylene-Based Triphasic Block Copolymers Containing Hydrophilic/Functional Block Elements
Abstract
1. Develop new, modular synthetic methods toward PIB-based barrier materials with three different micro-architectures (Figures MG1 and MG2). 2. Probe the relative importance of composition vs. architecture as a determinant of observed morphology and associated barrier and moisture transmission properties of PIB-based thermoplastic elastomers containing hydrophilic blocks. 3. Characterize barrier performance and water transmission capabilities of synthesized membranes (in collaboration with Natick). 4. Determine the most effective hydrophilic block among several proposed candidates including poly(acrylic acid), poly(ethylene oxide), and poly(ethylene imine). 5. Obtain continued support for this effort through collaboration with Army scientists at Natick and scientists at Defense Threat Reduction Agency (DTRA).
