Summary: With the growing concern of running out of crude oil and the rising prices of crude oil-based materials, there is a search for substitutes, such as bio-based polymers. This review compares the practical applications of selected crude oil-based and bio-based polymers based on their composition, chemical structure, and properties. It is found that many crude oil-based polymers can be effectively replaced by bio-based polymers without significant loss of properties. Furthermore, bio-based polymers have higher potential in many modern applications.

Summary: In this study, an antibacterial surface composed of thermoplastic poly-urethane (TPU) embedded with bentonite and MMT clay containing quaternary ammonium salts (QAS) was developed to prevent bacterial adhesion. The results showed that the nanoclay-embedded TPU surfaces with QAS significantly reduced the adhesion of E. coli and S. aureus, and a higher nanoclay concentration enhanced the effectiveness.

Summary: Ionenes are polymers with charges in their backbone, categorized as cationic or anionic, and segmented or non-segmented. Segmented ionenes exhibit thermoplastic elastomer properties due to low charge density, while non-segmented ionenes are widely used in various applications. Segmented ionenes are mainly studied at a fundamental level.
