Morphological Characterization and Microstructure Formation in Interpenetrating Polymer Networks

Description:

Interpenetrating polymer networks (IPNs) are multicomponent materials that enhance the compatibility of otherwise immiscible polymers by trapping the microstructure in a non-equilibrium state. By combining polymers with vastly different moduli, IPNs effectively disperse rigid polymers within a soft matrix, resulting in a reinforced elastomer. This approach significantly increases the modulus...

In Situ Morphology, Formation, and Dynamics of Heterogeneous Soft Matter Systems Elucidated via Liquid Phase Transmission Electron Microscopy

Description:

Herein, we present an overview of our studies of the morphology, dynamics, and formation of heterogeneous soft matter systems via the emerging technique of liquid phase transmission electron microscopy (LPTEM). This particular subset of materials, more commonly referred to as emulsions, is tremendously commercially and biologically relevant, encompassing applications in...

Chemical and Mechanical Properties of Drying Oils during Polymerization

Description:

Drying oils have been used as a binding medium for oil paints since the 15th century. These oil paints transition from a liquid-like paste to a solid-like film as a result of crosslinks forming between the oil molecules. These reactions have been extensively studied chemically, but other material properties are...

Using Visible Light to Synthesize Ladder Polymers and Modulate Dynamic Covalent Chemistry

Description:

Photochemistry allows chemists to harness the energy in specific wavelengths of light and use it to achieve new chemical transformations. These chemical transformations are often impossible or energetically demanding under traditional thermal conditions. My dissertation focuses broadly on different strategies to apply visible-light photochemistry and photocatalysis to the development of...

Polyelectrolyte Complexes of Random Copolymers and their Applications in Environmental Remediation

Description:

As polymer science has advanced as a field, so too have the uses for polymeric materials. We encounter polymers and plastics on a daily basis, and while their presence has greatly improved our quality of life, they have also had a profound and often negative impact on our environment. Plastic...

Body Heat-Activated Polymer-Mineral Composites for Vertebral Body Fractures

Description:

Polymer and polymer/ceramic composites known as bone cements are commonly used in musculoskeletal reconstructive surgeries where bone tissue fixation, reinforcement, or void filling may be needed. Polymethylmethacrylate, PMMA, was the initial (and currently only) FDA-approved bone cement for bone-void filling applications yet faces many inherent material-based challenges that impacts its...

Computational Modeling of Polymerization and Degradation of Complex Polymer Systems

Description:

Oil paintings are complex works of art, even on the molecular level. Drying oils cure into a solid film through autoxidation and polymerization reactions and then degrade, leading to changes in material properties and film stability. This chemistry can be captured in a computational model and used by researchers in...

Discovery, Investigation, and Implementation of a Photocontrolled Dynamic Covalent Reaction to Reversibly Tune Hydrogel Mechanics.

Description:

Part I: Evaluating the relationship between Crosslink Kinetics and Thermodynamics with the hydrogel mechanics. The past two decades have witnessed a surge of applications built upon dynamic covalent chemistry (DCC), both attributed to the scope of developed reactions as well as their modularity.1-3 These reactions have comparable strengths to their...

Photocontrolled Polymerization of Aryl Grignards for Pi-Conjugated Polymer Synthesis

Description:

Part I:Current approaches to synthesize π-conjugated polymers are dominated by thermally driven, transition-metal-mediated reactions. Herein we7 show that electron-deficient Grignard monomers readily polymerize under visible-light irradiation at room temperature in the absence of a catalyst. The product distribution can be tuned by the wavelength of irradiation based on the absorption...
