Final Project

 

Each student will choose a topic closely related to processing of polymers and/or composites. The project report must be emailed to the instructor as a single pdf file (the file name should follow the format: SE251A_LastName_FirstName.pdf or MATS261A_LastName_FirstName.pdf) by 11:59pm, Friday in the 10th week (not the Finals week). By the end of the 7th week, each student should have chosen the topic and received the approval from the instructor.

 

Sample topics: 3D printing of polymers or composites; Processing of electrically conductive polymers or composites; Processing of photovoltaic polymers or composites; Processing of piezoelectric polymers; Processing of piezoresistive composites, etc.
