Abstract
A series of poly(ethylene glycol)(PEG)-4,4â²-diphenylmethanediisocyanate(MDI)-poly(dimethylsiloxane) (PDMS) multiblock copolymers were synthesized by employing two-step growth polymerization technique. Atomic force microscopy (AFM) observed nanoscopically well-organized phase-separated surfaces consisting of hydrophilic domain from PEG and MDI segments and hydrophobic domain from PDMS segments even with 50Â wt.% PDMS in the copolymer, and the multiblock copolymer coatings presented a surface free energy of as low as 6-8Â mNÂ mâ1.
