Abstract [en]

In this article the synthesis, characterization, and surface orientation property of a biodegradable and biomimetic polymer are introduced. This phospholipid mimetic biodegradable polymer is synthesized by combining poly(trimethylene carbonate) (PTMC) with zwitterionic phosphoryl choline (PC) in a three-step synthesis. Since the glass transition of the polymer is around -20°C this material holds elastic properties at ambient temperature. This characteristic was used to induce surface enrichment as the polar PC end-group was enriched at the surface while treating films in an aqueous media. Film properties of the PTMC-PC amphiphile product revealed surface enrichment behavior, as the polar PC head group is oriented towards the surface. In addition, surface depletion of polar PC groups was the result when treating films under vacuum. This was observed by both contact angle measurements and electron spectroscopy for chemical analysis
