介绍了一种简单、新颖的微胶囊阵列制备方法。首先,通过光刻技术,在光敏聚酰亚胺光刻胶表面形成阵列化2D结构的圆形凹槽,以此作为微胶囊的模板,然后利用旋涂的方法,在微胶囊模板上进行SiO2纳米粒子自组装,SiO2纳米粒子选择性的进入模板表面的凹槽之中,再将配制好的PMMA材料旋涂在微胶囊模板表面,经过加热烘干,最终形成微胶囊阵列。这种微胶囊阵列可用于以图形化、阵列化微胶囊为先决条件的限制材料,尤其在高输出、多用途的传感器领域具有潜在的应用前景。
A simple and novel method for the preparation of microcapsule arrays was presented.First,through the photolithography technique,2D structure of arrayed circular grooves was formed on the surface of photosensitive polyimide photoresist as a template for microcapsules.Then,the silica nanoparticles were self-assembled on the microcapsule template by spin coating.The silica nanoparticles were selected into the groove on the template.And then the prepared PMMA material was spin coated on the template surface.After heating drying the arrayed microcapsules ultimately formed.Such microcapsule arrays can be used in the presence of graphical,arrayed microcapsules as a prerequisite for pace-confined materials.Especially in the field of high output and multi-purpose sensor has a potential application prospects.
