Transparent h-BN/polyacrylamide nanocomposite hydrogels with enhanced mechanical properties

Here we report a new trial to prepare transparent, tough and flexible polyacrylamide (PAM) hydrogels which is composed of a dually crosslinked single network by chemical crosslinking of N,N'-methylenebisacrylamide (BIS) and physical crosslinking of hydrophilic hexagonal boron nitride (h-BN nanosheets). The resulting h-BN/PAM nanocomposite hydrogels are highly transparent, and exhibit significantly enhanced mechanical properties compared to chemical crosslinking PAM hydrogels.
