Testing of polymeric materials under climatic conditions of Antarctica
Mičkal, Petr ; Sluková, Michaela (referee) ; Krmíček, Lukáš (advisor)
The bachelor's thesis generally deals with polymer materials and evaluates the possibility of testing their resistance to extreme climates of Antarctica. Described herein are various polymer materials, their characteristics, structure, properties and more thorough and detailed descriptions of selected polymers. The next section describes the basic types of degradation these polymers are exposed to, when facing the extreme conditions of the Antarctic climate. The practical part contains evaluations of tests made on the degraded polymer materials that were collected in Antarctica during the southern Antarctic season of 2013-2014 by Ing. Bc. Pavel Kapler, Ph.D, who is a superintendent at the Czech scientific station JG Mendel.

Clay minerals in polymeric materials
Zaťko, Petr ; Sluková, Michaela (referee) ; Krmíček, Lukáš (advisor)
The bachelor thesis deals with the clay minerals as fillers in polymer materials and their polymer/clay nanocomposites. The thesis brings an introduction to the structure of polymers and clay minerals and their application in polymer materials. The practical part of the thesis deals with testing the diffusivity of CO2 through the film made of recycled polyvinyl butyral with fillers Nanofil®5, Dellite® 67 and Cloisite® 93A and their comparison with reference samples from recycled PVB without added fillers and commercial films of extruded PVB.

Study of biocompatible polymers degradation
Oborná, Jana ; Márová, Ivana (referee) ; Vávrová, Milada (advisor)
This bachelor thesis is focused on biocompatible polymers degradation study. Both poly(D,L-lactic-co-glycolic acid)-g-polyethyleneglycol-g-poly(D,L-lactic-co-glycolic acid) copolymers and their forms modified with itaconic acid were monitored. This work verified the optimal analytical procedure for monitoring the degradation of investigated copolymers. Bio-degradation of polymers occured at 37 °C in phosphate buffer with pH=7.4. High performance liquid chromatography with UV-VIS detection of diode-array type was used for determation of the degradation products. Gel permeation chromatography with refractive index detector was used for the assesment of the change of molecular weight polymer chain after the degradation.

SMV-2012-19: Topography of thin polymer films
Urbánek, Michal
Topography measurement and properties' evaluation of thin polymer films deposited on silicon and quartz glass substrates. Measurements were carried out by atomic force microscopy (AFM)in contact mode. The roughness of polymer films were determined. Simultaneously analysis of individual phases in polymers was done by measurement of lateral forces.

Book of abstracts of the conference
Kovářová, Jana
The aim of the regular bilateral meetings of Czech and Slovak researchers in the field of macromolecular chemistry and physics is deepening of mutual awareness about current research projects and results not only of the academic character but also from the targeted and applied research.
