Figure Lengend Snippet: SEM images of MAA@Fe 3 O 4 ( a ), EDX spectrum of MAA@Fe 3 O 4 ( b ), VSM curve of Fe 3 O 4 and MAA@Fe 3 O 4 ( c ), FTIR spectra of Fe 3 O 4 and MAA@Fe 3 O 4 ( d ), XRD pattern of Fe 3 O 4 and MAA@Fe 3 O 4 ( e ), BET curve of MAA@Fe 3 O 4 ( f ), and TGA curve of the MAA@Fe 3 O 4 .

Article Snippet: Fourier transform infrared (FTIR) (Bruker, Billerica, MA, USA) and X-ray diffraction (XRD) (Siemens D500 diffractometer AG, Karlsruhe, Germany) analyses were performed to authenticate the synthesis and formation of the desired bonds.

Figure Lengend Snippet: a SAXS profiles of PAA240k, PAA240k+AM, PAA3k, and PAA3k+AM precursor solution with Lorentzian peak approximation. The fit result is correlated with correlation length (ξ). b In-situ ATR-FTIR spectra of PAA240k-AM during polymerization. Each spectra were recorded based on the polymerization time. c SAXS profiles of PAA-AM hydrogels with correlation length approximation and Lorentzian peak approximation. d AFM images of PAA3k-AM and PAA240k-AM. e Storage modulus ( G ′) and loss modulus ( G ′′) of PAA240k-AM and PAA3k-AM hydrogels.

Article Snippet: The FTIR spectrum was conducted by Bruker FTIR spectrometer Matrix-MF from the wavelength 400–4000 nm.
