Department of Chemical Engineering and Materials Science University of Southern California CHE 475: Physical Properties of Polymers Spring 2012Course Outline Polymersrepresent one of the most important class of materials that have revolutionized human life in the twentieth century, and continue to play an increasingly important role in emerging fields of various nanotechnologies including nanofabrication, biomimetic platforms of nanocrystal synthesis, smart optical systems, as well as tissue engineering, and drug delivery. CHE475 seeks to provide essential foundation necessary to understand molecularlevel behavior and macroscopic characteristics of polymers in melt, solution, blends, and solid state. This course presents thermodynamic, transport, thermal, mechanical, optical, and electrical properties of polymers, structureproperty relationship that provide polymers with unique characteristics compared to small molecules, key experimental techniques for characterization, together with their relevance to engineering applications, emphasizing understanding of underlying physics and physical chemistry.

Microphase separation of block copolymers Grading The course consists of two lectures per week. The final course grades are based on the statistical distribution of total points accumulated on three exams, problem sets, and a term paper. Exam I: 23% ExamII :23% ExamIII :24% Problemsets :15% Termpaper :15% Final Grade: 100% Exams There will be three exams incremental in nature, all in closed books, based on materials covered in the class and problems sets. A onepage equation sheet and a scientific calculator are permitted for use in the exams. Problem Set Problem sets will be assigned approximately every 23 weeks to ensure that the students keep current with the class materials and are prepared for the exams. These problem sets are to be turned in for grading on the specified due dates at the beginning of the class.No problem sets will be accepted late. Term Paper Each student will be required to prepare a report ona specific application of polymeric materials.th Detailed guideline will be discussed onJanuary 18. As a part of term paper writing process, a draft of your report will be peerreviewed by a fellow student, and you will review a fellow student’s draft as well.Grades will be based on both the quality of your reviews and on your final report. Special dates for the term paper are as follows. th February 13, Monday: First draft due. th March 19, Monday: Peer review due. th April 23, Monday: Final draft due. Collaboration Policy on Problem Sets Students are encouraged to discuss and work together on problem sets. However, each student must develop and submit his/her own solutions.Direct copying even a part of another student’s work is considered a cheating, and will result in zero score for all involved students.Academic Integrity Students must read and abide by the USC Student Conduct Code for academic integrity, which can be found athttp://webapp.usc.edu/scampus/1100behaviorviolatinguniversitystandardsand appropriatesanctions/.Plagiarism on problem sets and term papers, and consulting with another student during an exam all constitutes cheating in this course.Students are subject to disciplinary sanctions including failure in the course, and will be referred to the Office of Student Judicial Affairs and Community Standards for further review. Disability Any student requesting academic accommodations based on a disability is required to register with Disability Services and Programs (DSP) each semester. A letter of verification for approved accommodations can be obtained from DSP. Please be sure the letter is delivered to me as early in the
2
semester as possible. DSP is located in STU 301 and is open 8:30 a.m. – 5:00 p.m., Monday through Friday. The phone number for DSP is (213) 7400776. More information can be found at: http://sait.usc.edu/academicsupport/centerprograms/dsp/facultyinformation.html. Missed Exams Any student who misses an exam for a documented, valid reason (e.g., a medical situation, a family emergency, etc.) will be able to make up the exam. Students must arrange their absence in advance with their instructor (at least a week earlier than the exam date).Any student who misses an exam without a documented, valid reason will automatically be given a zero score. Class Etiquette Students are expected to be on time for the class.If you must arrive late or depart earlier, please do so quietly so that you do not disturb the class. Cell phones, laptops, and other distracting activities will not be tolerated and allowed during the class hours.
