Thiol–Ene Photopolymerization: A Simple Route To Pro-Antimicrobial Networks Via Degradable Acetals (Pandas), William Martin
Thiol–Ene Photopolymerization: A Simple Route To Pro-Antimicrobial Networks Via Degradable Acetals (Pandas), William Martin
Honors Theses
The World Health Organization (WHO) has brought the growing epidemic of antibiotic resistance bacteria to the attention of the public and has expressed the need for the development of new methods of defense. In this direction, bioactive aldehyde essential oils have been shown to effectively act as antibiotic and antifungal agents. These bioactive compounds, when used in their pure form, are volatile and lack environmental stability. In this thesis, we describe the synthesis of pro-antimicrobial networks via degradable acetals (PANDAs) using thiol-ene photopolymerization. PANDAs were used as a new model for the high loading and release of bioactive aldehyde-containing compounds …
Synthesis Of Polythioether Nanoparticles Via Thiol-Alkene/Alkyne Photopolymerization In Miniemulsion, Susan E. Walley
Synthesis Of Polythioether Nanoparticles Via Thiol-Alkene/Alkyne Photopolymerization In Miniemulsion, Susan E. Walley
Honors Theses
Emulsion-based processes – such as miniemulsion polymerizations – provide well-studied synthetic routes to polymer nanomaterials. Miniemulsion polymerizations are characterized as aqueous dispersions of small, narrowly distributed monomer droplets created through high shear and stabilized against Ostwald ripening/collisional degradation by addition of an appropriate surfactant and costabilizer. In this work, thiol–alkene/alkyne photopolymerization in miniemulsion is demonstrated as a simple, rapid, and one-pot synthetic approach to polythioether nanoparticles with tuneable particle size and clickable functionality. Nanoparticles with mean particle diameters ranging from 45 nm to 200 nm were synthesized through simple modifications to the miniemulsion formulation and processing parameters. Facile access to …
