摘要： The development of high-toughness glass has always been a major challenge in the fields of materials and chemistry, because stiffness and toughness are generally mutually exclusive. In this study, poly(ionic liquid) (PIL) glass with high stiffness and toughness is prepared by utilizing the supramolecular interactions between 1-vinyl3-ethylimidazolidinediamine salt (VD) and a small-molecule catechol (CA). High- toughness transparent materials of different stiffness can be prepared by adjusting the ratio of VD and CA. Soft transparent PIL materials are useful as pressure and temperature sensors because of their good conductivity. Stiff PIL materials (PIL glass) exhibits superior transparency, tensile strength (33.50 MPa), stretchability (224.42%), and toughness (63.78 MJ m-3). Furthermore, they exhibit strong adhesion, antibacterial properties, and resistance to freezing (-30 degrees C) and drying (80 degrees C). The glass can incorporate different fluorescent units, allowing for diverse colors under ultraviolet (UV) light, and can be patterned via noncontact UV patterning for information encryption. This research not only provides an innovative method for toughening glass and gels but also lays the groundwork for the development and utilization of functional glass materials.
