Beschreibung

Allgemeine Beschreibung

Polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene(SEBS) is a thermoplastic triblock copolymer with excellent mechanical, chemical, and thermal stability. It is a phase-segregated material and can be functionalized for further applications.

Anwendung

Polystyrene-block-poly(ethylene-ran-butylene)-block-polystyrene can be used:

• As a precursor to synthesize anion exchange membranes for alkaline fuel cells.
• To prepare super tough ternary polymer blends such as PS/LDPE/SEBS/xGnP ternary composites.
• To synthesize biocompatible conductive polymers. For example, PEDOT: PSSpolymer thin films for stretchable electrodes.
