The fabrication of porous-structured polymer films with patterned surface structures has recently attracted increased interest within the material science field. In this work, a series of microstructure scale patterned polymer films were obtained via breath figure methods (BF) with hydrophobic surface films based on self-assembled diblock copolymers by atom-transfer radical polymerization (ATRP). The surface characteristics and morphological properties, pore size, roughness, thickness, and wettability of the block copolymer films was studied in response to variation of the hydrophilic co-monomer structures. A significant improvement of the quality and order of the hydrophobic films was observed in response to thermal annealing and a consequent optimization of the assembly process.
具有图案化表面结构的多孔结构聚合物薄膜的制备近来在材料科学领域引起了越来越多的关注。在这项工作中，通过呼吸图法（BF），利用基于原子转移自由基聚合（ATRP）的自组装二嵌段共聚物制备了一系列具有微观结构尺度图案的聚合物薄膜，这些薄膜具有疏水表面。针对亲水性共聚单体结构的变化，研究了嵌段共聚物薄膜的表面特性、形态性质、孔径、粗糙度、厚度和润湿性。通过热退火以及随后对组装过程的优化，观察到疏水薄膜的质量和有序性有了显著改善。
