The structure of PEO–PPO–PEO triblock copolymers at the water/air interface

Neutron reflectivity was employed to detect a layer of water-soluble PEO–PPO–PEO triblock copolymers adsorbed from D 2O. The thickness of the layer (estimated from single-layer fits) grows linearly with the chain length in agreement with the theory of the “simple brush”. The results are consistent w...
