| Research Abstract |
In this study, phase separation of mixtures composed of a polymer and a monomer of the second polymer was induced by photo-polymerization with visible light at 405 nm.. By taking advantages of the gradient of the light intensity, the gradient of the co-continuous generated by spinodal decomposition was produced, leading to polymers with unidirectionally gradient co-continuous morphology. On the other hand, by combining with the computer-assisted irradiation method, the in-plane (XY) graded co-continuous morphology was generated and controlled. By doping light inert absorber into the mixture, the graded structures along the Z-(thickness) direction can be generated, leading to bi-axially graded bi-continuous structures. Finally, the surface free energy map of these co-continuous structures was observed contact angle of water.
