Breath-Figure Self-Assembly, a Versatile Method of Manufacturing Membranes and Porous Structures: Physical, Chemical and Technological Aspects

“…For evaporated films with a thickness above 100 nm, thermo-capillarity forces become dominant, resulting in instability caused by the Marangoni convection, either thermo- or soluto-capillary [ 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 ]. It should be mentioned that the analysis of the pattern inspired by thermo- and soluto-capillarity is an essentially non-linear one and involves complicated mathematical models [ 103 , 104 , 105 , 106 , 107 , 108 ].…”

“…Thus, the kinetics of evaporation, studied in [ 110 ], turns out to be crucial for constituting large-scale patterns. An apparatus utilizing self-organized liquid flow for the targeted modification of macromolecular systems in a solution was suggested in [ 112 ]. Marangoni-flow-induced patterns, observed under spin-coating of evaporated polymer solutions, were reported in [ 114 ].…”

Factors determining self-assembly of hyaluronan

“…HU aqueous or physiological solutions with the concentration of 0.5 wt.% were prepared by different dissolving ways of powder HU. The first type of solution was prepared on a laboratory orbital shaker at room temperature for 24 or 48 h. The second way was realized on a magnetic stirrer at 45 • C for 24 h and the last type of process involved dissolving in a temperature field flow chamber (TFFC) in temperature gradient for 24 h. Temperature gradient was generated by the temperature difference between the top cooling plate with 20 • C and the bottom heating plate with 50 • C, as described in our previous works (Minařík et al, 2017). These solutions were stored at 4 • C and diluted to the concentration of 0.1 wt.…”
