Polymer and Interface Science Lab
- Sample fabrication for material property characterization.
- Equipment for producing hybrid blends of polymer melts and liquid suspensions with different nano- to millimeter-scale fillers.
- Thermal, rheological, and static/dynamic-mechanical analysis.
This laboratory contains equipment for producing hybrid blends of polymer melts and liquid suspensions with different functional fillers of nano- to millimeter-scale size and to fabricate samples for material property characterization. Thermal, rheological, static/dynamic-mechanical, and physical properties of polymeric materials can be analyzed in the polymer lab. Surface characterization for wood and polymers can be also performed by measurements of contact angle and surface energy. The degree of cure and adhesive properties of thermosetting-polymers can be analyzed using thermal and mechanical properties.
