Phase-Separated Elastomers: Novel Syntheses and Characterization

Description:

Phase separation in segmented polymers provides distinct challenges in regard to their chemical reaction kinetics and characterization. Well studied, it has been shown that structure, phase separation and non-covalent interactions are key factors in the design of elastomeric polyurethanes. Specifically, this dissertation is focused on two areas: the synthesis of...

Effects of Confinement and Interfaces on Stress Relaxation and Stiffness in Polymer Films and Nanocomposites Characterized by Novel Fluorescence Techniques

Description:

Advancements in nanotechnology have led to the production of devices with components with sub-100 nm size scales. Studies have investigated how properties of polymers change when confined to nanoscale dimensions. However, stiffness-confinement studies have reported increases, decreases, and invariance with confinement for different polymer/substrate pairs, making it difficult to obtain...
