In this work

ESCA and SEM have been used to characterize the surface and bulk micro-phase morphology

surface chemical composition and the composition of polyether soft segment and TDI-HEMA hard segment based on two TDI-HEMA-PPO types of UV cured polyuretha-ne acrylates. The experimental results show that: (1) the microphase morphology of UV cured polyurethane acrylates strongly relies on the composition of soft and hard segments. Increasing the content of polyether soft segment

the extent of microphase seperation increased; (2) the sur-face elemenal composition is different from the bulk elemental composition; (3)
