“…Thin polymer films were obtained under drying of the polymer solution falling vertically along a metal, glass or polymer substrate. Mesoscopic patterning of the evaporated polymer films was observed by various groups and studied very thoroughly recently [6][7][8][9][10][11] . At the same time, the mechanism of the evaporation-induced mesoscopic self-assembly is still not clearly understood.…”

SummaryMesoscopically ordered self-assembled polystyrene, polycarbonate and polymethylmethacrylate films were obtained when polymer solutions were deposited on vertical plates and dried with hot air. It was shown that characteristic size (~ 50 µm) of the mesoscopic cell is practically insensitive to the polymer or substrate kind, while the thickness of the substrate plays a decisive role in the mesoscopic patterning.Junction angles of 120° and 90° were observed. Marangoni instability plays an important role in the cell's structure formation. A semi-quantitative model explaining the phenomenon of mesoscopic cell formation is proposed.

“…Srinivasarao, Shimomura and Pitois have related the phenomenon to atmospheric humidity, which can favor the formation of the honeycomb films [8][9][10][12][13][14] . L. Weh related self-organization to mass and heat transfer processes, which take place in the thin polymer film under the dewetting procedure.…”

“…It was concluded that size and structure of the patterns can be arranged by concentration, atmospheric humidity, etc. 220 Yu et al fabricated an ordered honeycomb structure using 4-dodecylbenzenesulfonic acid (DBSA)-doped polyaniline (PANI) via a water-assisted self-assembly method for the first time. Production of the 3D ordered macroporous structures from conducting polymers opens up new applications in electronic and electrochromic devices.…”

A novel root inclusion net method was designed to determine the fine root productions and turnover rates of 13-, 22-, and 38-year-old Larix principis-rupprechtii plantations in the whole growing season of 2012, and it was compared with the results of the sequential coring method and in-growth core method. All following values are reported in order for 13-, 22-, and 38-year-old L. principis-rupprechtii plantations. The mean values of fine root biomasses were 103, 261, and 356 g m -2 , about 76-78% of which were live fine root biomasses. The fine root productions were 86-118 g m -2 year -1 , 124-138 g m -2 year -1 , and 134-160 g m -2 year -1 , respectively. The fine root turnover rates were 1.12, 0.61, and 0.51 times year -1 , respectively, suggesting a relative slow fine root turnover in L. principisrupprechtii plantations. The carbon inputs into soil accompanying fine root turnover were 52, 58, and 94 g C m -2 year -1 . This organic carbon is a sizeable pool in the forest ecosystem. The results suggest that our new modified root inclusion net method is suitable for field-based assessment of fine root production and turnover.

“…The outstanding features of the honeycomb films are the regularity of their porous structure, the ease of fabrication [3], the control of the pore parameters (diameter and rim width) [4], and the wide range of applicable materials [5]. Applications range from improved photocatalyst activity [6] to cell culturing [7].…”

We used a self-organized polymer microhoneycomb structure as a template to form polyaniline structures that contain hexagonal voids. The polyaniline was synthesized in situ and adsorbed spontaneously on a polymer honeycomb structure that was immersed in the solution. Successive adsorption cycles led to thicker polyaniline coating. The characteristic honeycomb structure could be preserved during the process. Electrical measurements showed that the film resistance is the sum of contact and sheet resistance.
