Method & Evidence

AimTo develop and compare a one-step casting method for fabricating patterned polyelectrolyte complex (PEC) films with existing layer-by-layer assembly methods for polyelectrolyte multilayers (PEM) and assess their respective fabrication efficiencies and structural characteristics.
MethodComparative experimental fabrication and characterization
ProcedureFree-standing micro-patterned PEC films with microchambers were fabricated using a one-step casting process with applied pressure and a PDMS mold. These were then compared to micro-patterned PEM thin films with microchambers produced via layer-by-layer self-assembly on similar PDMS molds. Fabrication times, structural integrity (cap and wall thickness), and sensitivity to aqueous environments were evaluated.
