| dc.description.abstract | Materials are often classified into three primary groups: metals, ceramics, and polymers. Two or more dissimilar materials can be combined to create a unique composite material with the intent to incorporate the "best" properties of each individual material component and to bring new emerging characteristics. These resultant properties of composites are highly dependent on the types of materials, the processing/arrangement of these materials, and many other conditions. The most common engineered composites (e.g. reinforced concrete, fiber-reinforced polymers) are often used in structural applications. This thesis explores the electrical properties of ceramic-polymer composites as a function of particle morphologies, composite compositions, and processing techniques. More specifically, MWCNT/PMMA, SiC/PMMA, and SiC/glass composites were fabricated to investigate the effect of particle morphology and processing steps on the conductive filler network formation and resultant microstructural and electrical properties. Understanding of these effects would allow for tailoring composites for specific applications and properties and avoid unnecessary trial and error. Equivalent circuit fitting is applied to the electrical data to quantify the individual contributions of the filler and matrix materials with knowledge of the microstructural features. | |
