Not applicable.

The ability of students to apply selected instrumental methods (POM, CLSM, DSC, FTIR) to identify polymers and to examine their supramolecular structure, which reflects physico-mechanical properties, including correct sample preparation and proper choice of measurement conditions. The ability of correct interpretation of the obtained data and writing of compact and understandable report is other indispensable outlet of the practice.

Basic knowledge of chemical, molecular and supramolecular structure of polymers, their types and applications.

Not applicable.

The course uses teaching methods in form of Laboratory exercise - 4 teaching hours per week. The e-learning system (LMS Moodle) is available to teachers and students.

The classified credit is awarded after the fulfilling of all practices including the student self-measurement, all particular tests written at the practice beginning and the credit test in a minimum score of 60%, and after the handing all reports over.
1. The quarter of the mark comprises classification of written tests.
2. The quarter of the mark comprises classification of particular reports handed over in a demanded form (typography and format). The late handover decreases classification.
3. The quarter of the mark comprises classification of the self-measurement report handed over in a demanded form (typography and format) at the latest in the credit week.
4. The quarter of the mark comprises classification of the credit tests fulfilled in a minimum score of 60%.

1. Theme: Methods of direct and indirect imaging/deduction of supramolecular structure of polymers and their identification; selected methods for practices; the course of practices; the form of a report
2. Theme: Isothermal crystallization of selected thermoplastics observed under POM
Examination: Written test on polymer morphology and Polarizing Optical Microscopy (POM)
Outlet: Report from the measurement
3. Theme: Chemical etching of selected thermoplastics and imaging of uncovered polymer surface morphology using CLSM
Examination: Written test on methods for uncovering supramolecular structure of polymers and Confocal Laser Scanning Microscopy (CLSM)
Outlet: Report from the measurement
4. Theme: DSC of polyethylenterephthalat (PET) – structure changes caused by melt cooling rate; polymer identification
Examination: Written test on Differential Scanning Calorimetry (DSC) in a field of polymers
5. Theme: DSC isothermal crystallization of polymers measured on POM
Outlet: Report from both calorimetric measurements
6. Theme: FTIR and FTIR-ATR of selected polymers and fillers; identification of polymers
Examination: Written test on Fourier Transform Infrared Spectroscopy (FTIR) in a field of polymers
Outlet: Report from the measurement
7. Theme: FTIR and FTIR-ATR of co-extruded polymer packaging films; examination of the number of film layers on CLSM after their fracture in liquid nitrogen
Outlet: Report from the measurement
8. 8.–12. Theme: The student self-measurement of selected semicrystalline polymer products/materials from industry in order to identify and/or examine the difference between “good-bad” materials using POM, CLSM, DSC, and FTIR (the students choice).
Outlet: Compact and understandable report from measurement including correct form (typographic rules and format).
9. 13. Theme: Credit test

Not applicable.

The aim is the practical knowledge of selected methods for polymer identification and observation and deduction of supramolecular structure of selected thermoplastics, which is closely connected with final properties of these materials and which can be very easily changed by temperature process.

The attendance in all practices is obligatory. In case of excused absence, the practice can be compensated with another group or in the last week of the term. Unexcused absence is the reason for the loss of the credit.
Theoretical knowledge of students regarding the particular theme is examined by the written tests at the beginning of the practice.
The outlet of the practice is the report processed according to the instructions of the teacher and handed over in in time.
