Thermal And Mechanical Properties Of Polymers Using Molecular Dynamics, Daniel Glass, Alejandro Strachan, Lorena Alzate-Vargas, Chunyu Li, Benjamin Haley
Thermal And Mechanical Properties Of Polymers Using Molecular Dynamics, Daniel Glass, Alejandro Strachan, Lorena Alzate-Vargas, Chunyu Li, Benjamin Haley
The Summer Undergraduate Research Fellowship (SURF) Symposium
Polymer systems have gained attention during the past years because of their technological and industrial applications. Simulations, particularly molecular dynamics, are very useful for exploring properties of amorphous polymers, without using experiments. Our goal is to create a readily-available tool that will perform MD simulations in order to get thermal and mechanical properties (Glass transition temperature, Young Modulus) of the polymers. The work that has been done will be part of a tool to help people to learn about polymer properties including Glass Transition Temperature. We model some polymers at a scale of 10,000 atoms. The tool uses LAMMPS to …
Electrospinning Of Polycaprolactone Core-Shell Nanofibers With Anti-Cancer Drug, Sakib Iqbal, Mujibur Khan, Saheem Absar, Andrew Diamanduros, Samuel Chambers
Electrospinning Of Polycaprolactone Core-Shell Nanofibers With Anti-Cancer Drug, Sakib Iqbal, Mujibur Khan, Saheem Absar, Andrew Diamanduros, Samuel Chambers
GS4 Georgia Southern Student Scholars Symposium
Encapsulation of a model anti-cancer drug, 5-Fluorouracul (5-FU) into biocompatible core-shell nanofibers of polycaprolactone (PCL) nanofibers was fabricated using a coaxial electrospinning process. Our work aims to solve these issues using a novel method of fabrication of fibers featuring confinement of drugs within a biodegradable core-shell structure, thereby permitting sustained release of drugs to specific sites of treatment, such as tissues affected with tumor cells. The coaxial electrospinning was performed using a sheath polymer solution consisting of a 14 wt% PCL solution and a 5 wt% solution of 5-FU as the core solution. Dimethylformamide (DMF) was used as the solvent …
Rheo-Piv Investigation Of Fracture And Self-Healing In A Triblock Copolymer Gel, Benjamin A. Helfrecht, Travis L. Thornell, Kendra A. Erk
Rheo-Piv Investigation Of Fracture And Self-Healing In A Triblock Copolymer Gel, Benjamin A. Helfrecht, Travis L. Thornell, Kendra A. Erk
The Summer Undergraduate Research Fellowship (SURF) Symposium
Physically associating polymer gels have shown the ability to heal after failure, making them promising candidates for various medical applications or consumer products. However, the processes by which these materials self-heal is not well-understood. This study seeks to explain the self-healing behavior of the triblock copolymer poly(methyl methacrylate)-poly(n-butyl acrylate)-poly(methyl methacrylate), or PMMA-PnBA-PMMA, by probing the material’s post-fracture behavior with rheometry and particle image velocimetry (PIV). The self-healing behavior was studied by deforming each gel in shear until failure multiple times with “recovery” periods in-between. PIV was used to verify the occurrence of each fracture in both time and space. Stress …
