SEMINAR WORK
- Practical part of teaching - interpretation of spectrograms, thermograms, TGA, DSC, DMA
- determination of molecular weights (Mn, Mw, Mz) and their distribution by GPC method, viscometric determination of molecular weights (Mv).
- determination of free surface energy
- mechanical properties of the material (tensile testing, stress relaxation, hysteresis)
GENERAL AND SPECIFIC COMPETENCE:
The students are trained to work with selected techniques of materials and products characterization.
They are going to gain the knowledge and competence on certain methods and techniques of characterization and identification of polymers. Independent performance of analysis and quality control of materials and final products.
STUDENT OBLIGATIONS IN TEACHING AND THEIR PERFORMANCE
Attendance at all forms of teaching is mandatory, a minimum of 75%. Absence from the seminar must be compensated. Before taking the exam, the student is required to prepare and submit a seminar report.
CONDITIONS FOR OBTAINING SIGNATURES
After completing all forms of teaching, the student receives a signature, which is a prerequisite for taking the exam.
TEACHING METHODS
Lectures, seminars - from the practical part of teaching (related to certain characterization techniques)
MONITORING OF STUDENTS
The final grade from the course consists of the grade of the practical part and the written part of the 3 partial examps and / or the written exam. Students who have not passed the exam through the partial exams are required to write a written exam.
The exam consists of a written part and an oral part as needed. A student who wants a higher grade can take the oral exam. Passing the written exam is a condition for access to the oral part of the exam.
MONITORING OF THE COURSE QUALITY AND SUCCESSFULNESS:
Student questionnaire.
