Erratum to: J Mater Sci DOI 10.1007/s10853-017-0870-7
In Scheme 1, the structural formula of first segment [poly (acrylamide)] in the copolymer was incorrect; the carbonyl group was missing. It is correct in the revised scheme below. In Table 2, the correct heading for the first column should be concentration of PASV [C(PASV) (wt%)]. Also, the entries for the first column should be written as 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 for consistency with the data in the text. The authors regret these errors and any confusion they may have caused the readers. The corrected versions of the Scheme 1 and Table 2 follow.
