Self-Supported Printed Multi-Layer Capacitors, Michael James Joyce
Masters Theses
The increasing demand for miniaturized electronic devices has increased the need for rechargeable micro-power sources. Although lithium and lithium ion batteries have been utilized in these applications since the late 1990s, other energy harvesting technologies, such as thermal, mechanical, and solar, are now being used to augment batteries to enable systems to be self-powered. However, the lifetime of any battery is finite, which may be a major problem when the application is in a permanent structure or medical implant device. For power or significant energy storage applications, printed multilayer capacitors or supercapacitors are being explored as an enhancement, or replacement …
A Novel Silica-Based Nano Pigment As A Titanium Dioxide Replacement, Ryan Stoneburner
A Novel Silica-Based Nano Pigment As A Titanium Dioxide Replacement, Ryan Stoneburner
Masters Theses
This research focused on the evaluation of a new Silica-based pigment for the replacement of titanium dioxide (TiO2) in paperboard coatings. The silica-based pigment has shown the ability to be a replacement in terms of functionality and runnability. TiO2 is currently the highest opacifying pigment used in paper coatings, but it is also the most costly. Finding a less expensive pigment that doesn't reduce effectiveness is critical to reducing the cost of TiO2 formulations. To evaluate the new pigment, coatings will be applied using a Cylindrical Laboratory Coater (CLC) with varying amounts of TiO2 and …

A Study Of The Effects Of Polyacrylates On Water Retention And Binder Migration Tendencies Of Coatings, Wichan Charoenkitsupat
Masters Theses
Five commercial polyacrylate samples were used to study their effects on viscosity, water holding, and binder migration under non-pressure conditions. The polyacrylates used were different in acid level, degree of crosslinking, and type of polymer (copolymer and terpolymer). A series of coatings was prepared using a number two clay and three styrene-butadiene latexes of similar particle size and T⋁g but different degrees of carboxylation, then the polyacrylates were added at several levels. The coatings were evaluated for rheological properties, water loss rate and binder migration. The results show that with increasing amounts of polyacrylates, the viscosity increased and the water …
