本文采用化学交联法制备了N，N′-亚甲基双丙烯酰胺（BIS）和物理交联法制备了透明、坚韧、柔韧的聚丙烯酰胺（PAM）水凝胶。所得BN/PAM纳米复合水凝胶是高度透明的，并且与深色（GO）/PAM纳米复合水凝胶或化学交联PAM水凝胶相比，表现出显著增强的机械性能。因此，它为开发下一代透明，坚韧和灵活的水凝胶开辟了新的机会，这些水凝胶在光响应软机器人和液体微透镜等重要应用中具有很大的前景。
In this study, a facile way has been proposed to prepare transparent, tough and flexible polyacrylamide (PAM) hydrogels which is composed of a dually crosslinked single network by chemical crosslinking ofN,N′-methylenebisacrylamide (BIS) and physical crosslinking of hydrophilic hexagonal boron nitride (h-BN) nanosheets. The resultingh-BN/PAM nanocomposite hydrogels are highly transparent, and exhibit significantly enhanced mechanical properties compared to the dark (GO)/PAM nanocomposite hydrogels or chemical crosslinking PAM hydrogels. Thus it opens up new opportunities for developing next-generation transparent, tough and flexible hydrogels that hold great promise in such important applications as light responsive soft robot and liquid microlenses.
