摘　　要：为了实现可分像素程控的固态响应型光子晶体(photonic crystals,PCs),进而提升固态柔性反射式彩色显示器件性能,本研究通过使用纳米颗粒涂层来改善电活性聚合物(electroactive polymer,EAP)丙烯酸酯薄膜VHB4905表面的亲水性,使其具备良好的PCs组装条件,从而实现了在疏水EAP基底上制备PCs。通过对比在不同层数亲水涂层上自组装PS二维光子晶体(two-dimensional photonic crystals,2D PCs)的反射光谱,发现了在丙烯酸酯薄膜上涂覆2层纳米亲水涂层时自组装PCs的效果最好。通过对比其与传统玻璃基PS 2D PCs的反射光谱,发现改性后的丙烯酸酯基2D PCs拥有更高的反射率增强峰值。该结果验证了经过亲水涂层改性后在EAP上组装PCs的可行性,也为进一步以EAP作为驱动源的响应型PCs的制备提供了技术基础。The final purpose of this study is realizing a solid-state responsive photonic crystals(PCs),which is constructed from program-controlled pixels,and improving the performance of reflection type flexible solid-state color display device.In this study,PCs growth on electroactive polymer(EAP)acrylate film VHB4905 substrate is achieved by coating nano hydrophilic particle on the substrate,which can create good conditions for PCs assembly.By comparing the reflection spectra of self-assembled PS two-dimensional photonic crystals(2 D PCs)with different layer number of hydrophilic coatings,it is concluded that two layers of nano hydrophilic coatings is the best for self-assembling on acrylate film.There has a higher reflectivity enhancement peak in the reflection spectrum of PS 2 D PCs on the modified acrylate substrate compared with that of PS 2 D PCs on traditional glass substrate.So,the feasibility of assembling PCs on EAP modified by hydrophilic coatings is verified.Furthermore,a technical basis for preparing responsive PCs driven by EAP is provided.
