Sample interview questions: How do you approach the design and synthesis of polymer nanocomposite materials?
Sample answer:
Approaching Polymer Nanocomposite Design and Synthesis
- Define Objectives: Establish clear goals for the desired properties and applications of the nanocomposite.
- Select Materials: Choose suitable polymer matrix and nanofillers based on their compatibility, reinforcement capabilities, and desired properties.
- Determine Nanofiller Dispersion: Develop strategies for effective dispersion of nanofillers within the polymer matrix, optimizing their interaction and avoiding agglomeration.
- Control Nanofiller Morphology: Manipulate the shape, size, and surface properties of nanofillers to fine-tune their reinforcement and functional characteristics.
- Tailor Polymer-Nanofiller Interface: Enhance the bonding between the polymer matrix and nanofillers through surface modifications, compatibilizers, or functionalization.
- Optimize Processing Conditions: Determine suitable processing techniques (e.g., melt extrusion, solution c… Read full answer
