Desenvolvimento de um sistema automatizado para a fabricação de filmes automontados

Abstract: we describe the construction of a low-cost computer controlled device for layer-by-layer film fabrication. The software allows to control multiple material deposition, washing and drying steps and the time for each operation. To test the device, we produced and characterized self-assembled films of conductive polymers by alternating poly(o-methoxyaniline) (POMA) and poly(3-thiophene acetic acid) (PTAA) via the layer-by-layer technique.Keywords: layer-by-layer technique; Langmuir-Blodgett technique; automated d… Show more

“…The Journal of Physical Chemistry B ARTICLE Self-assembly was performed using a homemade device, which basically consists of an analogic XY recorder that has been adapted to function as an immersion and displacement robot controlled by software. 65 The bilayers were assembled by the subsequent immersion of ITO substrate in PANI and PSS solution, respectively, for 3 min. Before each step, the films were washed in the acidic solution (pH 3.0) for 15 s and then dried in air for 5 min.…”

“…A number of commercial and homemade programmable lifts and mechanical robots have been developed. [11][12][13][14][15][16][17][18][19][20][21] Spraying of alternating polyelectrolyte solutions has been suggested for fast coating of large areas. [22] Here, we suggest another approach for the automation of LbL deposition.…”
