Stability of ZOL loaded PEC films at Ge-IRE substrates against detachment. The ν(SO2) band integral from TRANS-FTIR spectra of thin PEC-0.9 (a) and PEC-1.1 (b) films of ZOL/CS/PEI-M-25 K-1:5 (cubes), ZOL/CS/PEI-25 K-1:5 (triangles) and ZOL/CS/PEI-750 K-1:5 (circles) is plotted versus time (0, 1, 60, 1200 min) of contact to release medium (dry state).
