Advances in Fabrication Materials of Honeycomb Structure Films by the Breath-Figure Method

Abstract

Creatures in nature possess almost perfect structures and properties, and exhibit harmonization and unification between structure and function. Biomimetics, mimicking nature for engineering solutions, provides a model for the development of functional surfaces with special properties. Recently, honeycomb structure materials have attracted wide attention for both fundamental research and practical applications and have become an increasingly hot research topic. Though progress in the field of breath-figure formation has been reviewed, the advance in the fabrication materials of bio-inspired honeycomb structure films has not been discussed. Here we review the recent progress of honeycomb structure fabrication materials which were prepared by the breath-figure method. The application of breath figures for the generation of all kinds of honeycomb is discussed.

Highly ordered and robust honeycomb films with tunable pore sizes fabricated via UV crosslinking after applying improved phase separation

“…As seen in Table 1, the ordering of the patterned films becomes better when the films were prepared at higher humidity and lower temperatures. This observation is consistent with previous studies [4,18,24]. Table 1 Effect of methanol content on the mean pore diameter, standard deviation of the pore diameters, number density, and entropy.…”

Conductive Polymer Porous Film with Tunable Wettability and Adhesion

“…Various fabrication techniques of porous materials have been developed, such as phase separation [8,9,10], emulsion templating [11,12], direct foaming [7,13], polymer foam replication [14,15], breath figures [16,17,18] and freeze drying [19,20,21,22]. Compared with other methods, freeze drying shows some advantages, such as large area preparation, with no need for further purification, and obtaining a number of pore morphologies and nanostructures by changing variables during freezing [22].…”

Straightforward functionalization of breath figures: Simultaneous orthogonal host–guest and pH-responsive interfaces

“…Thus, photolithography, patterning or microcontact printing of functional molecules are among the most extended strategies [32][33][34][35][36][37][38][39][40]. The above mentioned methodologies usually require multistep procedures and the final resolution is associated to the methodology employed.…”
