Raft Polymerization Of Sulfonamide-Containing Methacrylamides, Michael B. Sims
Raft Polymerization Of Sulfonamide-Containing Methacrylamides, Michael B. Sims
Honors Theses
Targeted delivery of cancer therapeutics offers an exciting new opportunity for utilization of controlled polymerization techniques. However, a major obstacle in achieving the desired therapeutic effect is facilitating endosomal release of active agents following endocytosis. Peptides and pH-responsive polymers have been utilized as a means of triggering endosomal release via phase transition-induced membrane disruption. Unfortunately, the fidelity by which the pKa of these polymers/peptides can be varied is limited, such that it reduces their versatility in altering the phase transition point to best match the endosomal pH of a particular cell-type. Herein, we report the controlled polymerization of library of …
Effects Of Varying The Cure Profiles Of An Epoxy-Amine System, Patrick W. Hollingsworth
Effects Of Varying The Cure Profiles Of An Epoxy-Amine System, Patrick W. Hollingsworth
Honors Theses
The cure of an epoxy prepolymer with an amine hardener induces stress in thermosetting systems. The extent of residual stresses in the cured epoxy-amine thermosets are dependent on several factors; one of which is the cure profile utilized. The effect of cure profile on cure induced stresses of an epoxy-amine thermoset was examined in the current study. A difunctional epoxide based on diglycidyl ether of bisphenol-A (DGEBA) and a tetrafunctional amine curative were used to conduct this study. Two cure profiles were selected to prepare samples of varying degrees of stress in the cured thermosets. The first was constant heating …
