Abstract研究了不同挥发速率下厚度较薄的凹液层胶体悬浮液的干燥花样。Panasonic照相机用于拍摄宏观干燥花样。结果表明,随着挥发速率的减小,马兰哥尼对流强度下降,胶体悬浮液的干燥花样更为平整均匀。在较低的挥发速率下可避免宽环花样形成,制备得到表面平整的薄膜,反射光谱证明其可作为三维光子晶体材料。
Other AbstractWe studyed the effect of evaporation rate on the drying pattern of thin concave layer colloidal suspension. Panasonic camera was used to capture macroscopic pattern. It is shown that with the decrease of evaporation rate, Marangoni convection strength descends, more uniformed drying pattern is obtained. Broad-ring pattern can be avoided and homogeneous film is prepared at lower evaporation rate, and reflection spectrum shows the film can be three-dimensional photonic crystal material.
