Materials Science: Bonding Models, Alloys and Composite Design · Semester 2
Polymer Properties: Structure–Property Relationships and Environmental Impact
Students will explore the general properties of common polymers (plastics) and relate them to their everyday applications and disposal.
Key Questions
- Explain how the degree of crosslinking, crystallinity, and molecular mass of a polymer collectively determine its tensile strength, glass transition temperature, and chemical resistance.
- Distinguish between thermoplastics, thermosets, and elastomers at the molecular level, predicting how each class responds to prolonged heating, mechanical deformation, and organic solvent exposure.
- Evaluate the lifecycle environmental impact of synthetic versus bio-derived polymers by comparing energy input per kilogram, carbon footprint, and end-of-life degradation pathways using quantitative data.
