| The goal | In this course, students will gain knowledge on the separation and production of natural polymers, their properties, modification, application, and degradation. Students will be especially acquainted with the benefits of natural polymers in comparison to synthetic regarding their reproducibility as raw materials and their environmental aspects - biodegradability, non-toxicity. | |||
| The outcome | Students are familiar with natural polymers, their properties, and their application as materials. They know the difference between natural polymeric materials and synthetic polymers, methods of manufacturing the products based on natural polymers. Students can choose proper material based on natural polymers for a certain application, especially as a more environmentally friendly alternative to other materials. | |||
