利用各种掩膜在三组分光化学反应体系中创建多重图案

Multi-component polymer mixtures with novel structures can exhibit novel physical properties and have a variety of potential applications in materials engineering. Via cell dynamical simulations, the phase behavior of three-component, photoreactive blends under different kinds of masks confinement has been studied systematically and multiple ordered defect-free morphologies have been obtained.Firstly, the sample is irradiated by light through various shaped masks, which make the C regions pinned and thereby promotes the self-assembly of A and B components into ordered domains.When the masks are removed, the photoreaction of the AB blend leads to different periodic patterns.These results provide an easy method to create hierarchically ordered, defect-free materials in experiment and engineering technology.
