✦ Synopsis

Poly(ethylene oxide)-poly(propylene oxide)poly(ethylene oxide) (PEO-PPO-PEO) triblock copolymers were immobilized on thin fluorocarbon films with a structure very similar to poly(tetrafluoroethylene) (PTFE) using a microwave argon plasma. Fourier transform infrared attenuated total reflection and spectroscopic ellipsometry were used to study this process. After investigating the decomposition behavior of PEO-PPO-PEO triblock copolymers, we found that under appropriate plasma conditions, this material can be immobilized on a PTFE-like surface, while its general structure is preserved.

Pluronic surfactants, PEO-PPO-PEO triblock copolymers, have been investigated widely due to their protein-resistant properties in applications as coatings for implants and in controlled drug release systems. We have studied a wide range of these copolymers, varying in both PEO and PPO block size, by

## Abstract Three novel polyethylene oxide‐containing amphiphilic triblock copolymers (PEO‐PU‐PEO) with PEO MWs 550, 2000, and 5000, were blended with a segmented polyurethane (PU). It was expected that the block copolymers would act as surface modifiers to produce surfaces rich in PEO. The solid s
