    • To determine the film mickness, we used a method provided by reference 38. The relative sensitivity factors were iN, 0.477 and i Si, 0.328, and the photoionization cross sections were σN, 1.8 and σSi= 0.817 as provided by the XPS manufacturer. The elemental concentrations in the adsorbed polymer film and mica substratum were calculated to be Cnad, 10.46 M and CSisu, 16.68 M, respectively. The inelastic electron mean free paths were calculated to be λSisu, 3.33 nm in mica and λSiad, 3.99 nm and λNad, 3.11 nm in the polymer film, assuming a mica density of 2.8 g/cm3 and a polymer density of 1.127 g/cm 3. The N-to-Si molar ratio in the film was determined to be 4.9, 12.3, The film thickness at full coverage was obtained from the surface coverage versus thickness plot

    • Calculation of the polymer contour length was performed as follows: The molecular weight of the NIPA polymer was 2.06 × 105 g/mol. The average molecular weight of one unit was 115 g/mol when the polymer contained 87% NIPA, 12% VI, and 1% PEG. Thus, we obtained an average degree of polymerization of 1790, which corresponds to an average chain length of 448 nm
