Modeling and Data Analysis of Conductive Polymer Composite Sensors

MODELING AND DATA ANALYSIS OF CONDUCTIVE POLYMER COMPOSITE SENSORS Hua Lei Department of Chemical Engineering Doctor of Philosophy Conductive polymer composite sensors have shown great potential in identifying gaseous analytes. To more thoroughly understand the physical and chemical mechanism of this type of sensors, a model was developed by combining two sub-models: a conductivity model and a ...

Modeling and Fabrication of Ionic Polymer-metal Composite (ipmc) Sensors

MODELING AND FABRICATION OF IONIC POLYMER-METAL COMPOSITE (IPMC) SENSORS By Hong Lei Ionic polymer-metal composites (IPMCs) are an important class of electroactive polymers (EAPs) with built-in actuation and sensing capabilities. They have received tremendous interest for their potential in various sensor applications. In this dissertation, a physics-based dynamic model is proposed for cantilev...

SYNTHESIS OF AL2O3-NI COMPOSITE POWDERS BY CO-PRECIPITATION METHOD

The synthesis of micro-sized, uniformly distributed Al2O3-15Vol% Ni powders were studied through three step co-precipitation of hydroxides mixtures from proper solution, calcination at air atmosphere and final step of calcined powders in a carbon bed. Al and Ni hydroxide and amorphous phase were first obtained from their salt’s solutions through chemical co-precipitation method by adjusti...

Conductive polymer-based sensors for biomedical applications.

A class of organic polymers, known as conducting polymers (CPs), has become increasingly popular due to its unique electrical and optical properties. Material characteristics of CPs are similar to those of some metals and inorganic semiconductors, while retaining polymer properties such as flexibility, and ease of processing and synthesis, generally associated with conventional polymers.
