      Term-project report    (20 %)

      In-class presentation   (20 %)

      Final exam                  (40 %)

 

 

TERM-PROJECT:

                        A special Polymer Nanocomposites system will be assigned for 1 or 2 students whom will submit a report

                        and perform in-class presentation with discussions.

 

PROJECT FORMAT

                        Term-project would basically follow the course content with much higher details on the production, characterization,

                        structure, morphology, properties, applications, etc. of the specific polymer nanocomposite system assigned.
