The Development of Microfluidic Devices Fabricated From Poly(dimethyl) Siloxane
"This dissertation outlines work in the field of polymeric microfluidic (muFL) devices, particularly the design and fabrication of microfluidic devices using poly(dimethyl) siloxane (PDMS). Fabrication involved lithographic and ""soft"" lithographic techniques. Capillary electrophoretic separation …

Stress and microstructure development in particle-based coatings
… of drying uniformity. Silicon cantilevers with poly(dimethyl siloxane) (PDMS) walls along the perimeter were used to suppress the effects of lateral drying during stress measurement. The walled cantilevers were used to characterize stress development in ceramic particle coatings and latex films. …

Improving hydrophilicity of silicone elastomer by IPN formation with hyaluronan
… this research was to create an interpenetrating polymer network (IPN) materials of poly(dimethyl siloxane) (PDMS) and hyaluronan (HA) with such properties. The results in this work indicate the successful synthesis of these HA-PDMS IPN materials. These elastomeric materials had improved …

Structure-property relationships of electron beam irradiated monomeric and polymeric systems
… for electron beam(EB) irradiated monomeric and polymeric systems. The objectives were to study the feasibility of preparing systems of potential application, and to characterize these systems in terms of structure-property behavior. In this thesis, the basic theories on radiation chemistry were …

Toward commercializable microphase-separating copolymer electrolytes for rechargeable lithium batteries
Microphase-separating copolymers have been shown to possess the electrical properties of a polymer liquid and the mechanical properties of a solid. In the past, these materials had to be produced via anionic methods that are not easily scalable. To circumvent this problem, two approaches were …

Shock initiation of explosives under the microscope
… ranging from low-density powder compacts to polymer-bound explosives which has no void space on the microscale. The temperature histories have given us valuable insight into the dynamics and reaction kinetics of explosive materials under shock compression by thin flyers. Short duration shocks …

Studies of adsorption and stabilization of silica suspensions using well-defined polymeric dispersants
Solutions of poly(2-ethyl-2-oxazoline) and poly(2-methyl-2-oxazoline) in water and several alcohols were characterized by light scattering and cloud point measurements. The second virial coefficients in water were found to decrease with increasing temperature, reflecting lower critical solution …

Siloxane-Based Reinforcement of Polysiloxanes: from Supramolecular Interactions to Nanoparticles
Polysiloxanes represent a unique class of synthetic polymers, employing a completely inorganic backbone structure comprised of repeating –(Si–O)n– 'siloxane' main chain linkages. This results in an assortment of diverse properties exclusive to the siloxane bond that clearly distinguish them from …

Electromechanical Characterization of Poly(Dimethyl Siloxane) Based Electroactive Polymers
… cross-linking polar cyano phenyl (CN) groups on poly (dimethyl siloxane) (PDMS) and 2) to characterize the electromechanical properties of the resulting CN-PDMS blend as an electroactive actuator. Materials responding to an external stimulus are referred to as electroactive materials. There are …
