摘      要：Comprehensive Summary,Polymethyl methacrylate(PMMA)has been widely applied in diverse fields such as medicine and engineering materials due to its good hydrophilicity and ***,another term for PMMA,Plexiglas,means that it is water *** features of PMMA are valuable but seem *** explore the underlying mechanism of the paradoxical properties,the interactions between PMMA and water have been investigated by atomic force microscopy(AFM)-based single-molecule force spectroscopy(SMFS).The single-chain elasticity of PMMA obtained in aqueous solutions is significantly different from that obtained in non-aqueous environments,implying that PMMA can form hydrogen bonds with water molecules.
