• Multifunctional Polymer Composites

•Goal:Understand the processing-structure-property relationship

•Potential applications are structural (i.e., automotive, aerospace), housing for electronics, electrostatic dissipation, electromagnetic interference shielding

• Adaptable/responsive Polymer Particles (Figure)

•They can alter their geometry, flow and adsorption characteristics on command

•Goal: Tune/Control the stresses responsible for the property changes by identifying the proper material-trigger combination

•Potential applications are drug delivery vesicles, reinforcements is smart composites

Course selection / program of study

• Should support your research project– if you are contemplating a thesis

• Should support your interests• Should be completed with input from

your (thesis) advisor, who approves (signs) your program of study

• Should support your taking of the qualifiers – see handbook for test areas

Number of classes / schedule -(MS) thesis students (21 hours of classes

and 9 hours of thesis)

• Fall 2007 - 2 classes (6 hrs) + thesis (15 hrs)• Spring 2008 - 2 classes (6 hrs) + thesis (15 hrs)• Summer 2008 - 1 class (3 hrs) + thesis (18hrs)• Fall 2008 - 2 classes (6 hrs) + thesis (15 hrs)• Spring 2009 - Thesis (21 hrs)

• N.B. - always take 21 hours

16

Number of classes / schedule -MS non-thesis students (30 hours of classes)

• Fall 2007 - 4 classes (12 hrs) • Spring 2008 - 4 classes (12 hours) • Summer 2008 - 2 classes (6 hrs)

– or -• Fall 2008 - 2 classes (6 hrs)• N.B. - You may consider ME 89XX (up to 3

hours of special projects) instead of thesis. This replaces one class.

• Modify the schedule of classes as needed and due to class offerings.

17

Full time status

• You must register for a minimum of 12 hours per semester to be considered “full time.”– needed to maintain certain benefits

• Non-thesis GTAs should sign up for 3 hours of ME 8997 (audit only).– helps bring you to 12 hours per semester

• Thesis GTAs may sign up for 3 hours of ME 8997 (audit only).– it’s better to sign up for more thesis instead
