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

“…Various experimental techniques were successfully applied for breath-figure self-assembly, including drop-casting [ 66 , 67 , 68 , 69 , 70 , 71 ], spin-coating [ 72 , 73 , 74 , 75 , 76 , 77 , 78 ], the “doctor-blade” technique [ 79 , 80 ], and dip-coating [ 46 , 54 , 58 , 81 , 82 , 83 ]. When breath-figures-inspired patterns are formed under drop-casting, a drop of polymer solution is deposited by a precise micro-syringe (or micro-injector) on a solid substrate and exposed to air flow with a controlled humidity [ 66 , 67 , 68 , 69 , 70 , 71 ]. The spin-coating process involves putting a polymer solution on the center of the substrate, which is either spinning at low speed or not spinning at all.…”

Pattern formation in thin polymeric films via electrohydrodynamic patterning

“…Over the past few decades, the urgent need of micro- and nano-structures for manufacturing high-performance devices, such as integrated circuits, optoelectronic devices, and sensor arrays, has motivated the development of new patterning techniques. 1–5 In 1999, Chou et al observed that a periodic pillar array with a micrometer scale was formed in a thin polymer film. 6–14 Although without the external electric field, the key driving force for the formation of the micro-/nano-structures is the internal localized electrical field generated between the contactor and the polymer film.…”

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

“…Various experimental techniques were successfully applied for the breath figures self-assembly, including: drop-casting [66][67][68][69][70][71], spin-coating [72][73][74][75][76][77][78], the "doctor-blade" technique [79][80] and dip-coating [46,54,58,[81][82][83]. When breath-figures inspired patterns are formed under drop-casting a drop of polymer solution is deposited by the precise micro-syringe (or micro-injector) on the solid substrate and exposed to the air flow possessing controlled humidity [66][67][68][69][70][71].…”
