摘要

通过引入预相分离过程对传统呼吸图法过程进行改进，改变了PEG在聚合物共混溶液中的初始分布，从而以一步法制备出含有2D微半球结构的聚合物微结构薄膜. 通过设计预相分离时间分别为10、20及30 min，PEG的分子量为2000、6000及10000，不同PEG分子的含量配比为1:9、2:8及3:7，以及小分子量PS18000的引入，探讨了制备条件的改变对微结构的形貌及尺寸的影响，并详细分析了条件对于微结构影响的原因. 最终设定预相分离时间为10 min、PEG分子配比为3:7及使用小分子PS18000，通过一步法制备含有较多2D微半球结构. 该制备方法将为快速、大面积地制备2D微半球结构提供一种新思路.

Abstract

Traditional breath figure method was improved

via

the introduction of polymer pre-phase separation. The morphology and size distribution of microsturctures prepared could be finely tuned by pre-phase separation time

PEG molecular weight

the ratio between different PEG molecules

and blending with small PS molecules. Specifically

compared with 20 and 30 min

the pre-phase separation time of 10 min could yield the most uniform structures; PEG2000 stood out from all PEG molecules tested with molecular weight from 2000 to 10000 and afforded microstructures of the highest compactness and homogeneity; introducing PEG200 the even smaller molecule would enhance the phase separation degree between PS and PEG. Furthermore

ratio variation between PEG200 and PEG2000 suggested that the maximal micro-convexes could be obtained at ratio of 2:8

while a honeycomb morphology was observed at 3:7. Among all the factors investigated

PS molecular weight played a dominant role on topography regulation. PS with lower molecular weight could reduce the molecular chain twisting for all polymer components

which conduced to the polymer phase separation. Addition of PS18000 rather than PS260000 could increase micro-convex amount as well as improve the uniformity of as-prepared structures dramatically. The honeycomb micro-hemisphere arrays were ultimately achieved through one-step breath figure method under the optimized conditions of pre-phase separation time as 10 min

PEG200:PEG2000 ratio as 3:7

and PS18000 participation; in the meantime

three structures including holes

half-holes

and convexes appeared on the substrate. Scrutinize of the underlying mechanism indicated that distribution and assembly of PEG molecules inside or on the surface of water droplets functioned decisively towards the topography of structures formed. This study provides novel insight into highly efficent fabrication of micro-hemispheres arrays.
