FT-IR analysis of a PLGA research sample · November 2013
2013–2014
Understanding structure before processing
PLA and PLGA research samples were synthesized and studied using FT-IR, NMR and DSC to examine chemical structure and thermal properties. Drawings, 3D form studies and injection-molded prototypes connected material analysis with processing research.

From form and processing to material properties
Processing conditions and forms were studied for filaments, membranes and molded parts, with load and displacement recorded for individual samples. Follow-up in-vitro degradation studies tracked tensile properties, mass and pH over time.
Collaborative research on tube surface coatings · 2020–2021
2020–2021
Researching polymer surfaces
Polymer tube surface coatings were studied in collaboration with the Korea Institute of Ceramic Engineering and Technology. Contact angles on tubes and flat substrates, together with coating stability over time, were compared to examine surface properties.

Connecting particle processing with observation
Records linking analysis requests before and after microsphere processing include FT-IR, NMR, GPC and DSC. Later SEM observations added evidence of particle shape and surface features to the assessment of processing results.
