| The goal | In this course, students will gain knowledge on separation and production of natural polymers, their properties, modification, application and degradation. Students will be especially acquainted with 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 application as materials. They know difference of natural polymeric materials with respect to synthetic polymers, methods of manufacturing the products based on natural polymers. Students are able to choose proper material based on natural polymers for certain appplication, specially as a more environmentally friendly alternative to others material. | |||
