  • How are H2O molecules bonded with Pam chains?
  • Nevertheless, in 4.1 m and 7.6 m WIPSEs, around 42% and 34% of H 2 O molecules are directly bonded with PAM chains by hydrogen bonds (including H 2 O (PAM) z, H 2 O (PAM) z (TFSI) y, H 2 O (PAM) z (Li) x, H 2 O (PAM) z (Li) x (TFSI) y ), as PAM could partially replace TFSI −, which confine the movement of H 2 O molecules.
  • How is a butyl rubber bonded to a Pam hydrogel?
  • The butyl rubber was chemically bonded to the hydrogel surface through silane coupling agent. In an environment with a relative humidity of less than 5 %, the weight loss of the butyl rubber coated PAM hydrogel was only 20 wt% after 80 h.
  • Do PVA/Pam hydrogels have the same stretch limit?
  • For PVA/PAM hydrogels fabricated by different process, the PAM have the same volume concentrations (C PAM) and chemical network chains ( nPAM ), thus they have the same stretch limit of PAM chains (λ limPAM) in hybrid hydrogels. In control gels and F-T gels, PVA components have the same volume concentration (C PVA ).
  • Does PVA/Pam form intermolecular hydrogen bonds?
  • This confirms that some intermolecular hydrogen bonds formed, suggesting formation of the interaction between PVA and PAM. A strong band at 1626 cm − 1 in the spectrum of PVA/PAM is attributed to the vibration absorption of C O, indicating disappearance of C C. The control, F-T and A-S gels show the same results due to their same functional groups.
