N2 - Abstract: For Zn-nanopapers obtained from grafting of Zn(II)-terpyridine complex (Zn-tpy) into tCNFs (2,2,6,6-tetramethylpiperidine-1-oxyl radical, TEMPO, oxidized cellulose nanofibrils), their optical hazes were first found to be highly dependent on alcohol-characteristic solvent stimulation. By addressing the controllable issue of benzyl alcohol (BA) disposal, the optical haze of Zn-nanopaper was adjusted to regulate from BA-induced instability wrinkling and swelling patterns, which was dictated by Zn-nanopaper thickness. Moreover, upon long-term UV radiation, these Zn-nanopapers exhibited stable UV-blocking, which, together with the optical haze adjustment, offered an opportunity for utilization in fluorescent lamps, flat panel displays or glass walls. Graphical abstract: [Figure not available: see fulltext.].
