A novel physically linked double-network (DN) hydrogel was prepared by natural polymer KGM and synthetic polymer PAAm. The DN hydrogels exhibit good mechanical properties, cell adhesion properties, and can be freely shaped, making such hydrogels promising for tissue engineering scaffolds.

<p>The development of adsorbents into structured and robust forms remains a challenge for emerging porous materials. In the context of porous boron nitride (BN), studies point to a tradeoff between mechanical stability, porosity, density, and adsorption kinetics. Approaches towards shaping and densification of porous BN have been mostly empirical since a detailed understanding of its formation mechanism, and how it impacts mechanical strength and porosity, is lacking. Here, we demonstrate a synthesis method that can directly produce a mechanically robust monolithic porous BN (mpBN) from an easily scalable polymeric precursor, which results in the highest volumetric surface area among porous BN samples to date. mpBN exhibits a high bulk density, 50% higher than BN powders and over ten times higher than the structured BN aerogels, while maintaining fast sorption kinetics. mpBN presents good mechanical strength, with hardness of 66.4 ± 4.5 MPa, <i>i.e. </i>one to two orders of magnitude higher than structured aerogels. We propose a mpBN formation mechanism which reveals that the crosslinked intermediates are responsible for the high mechanical strength of the final material. Our approach produces a form of BN that addresses the limitations of other adsorbents, and facilitate their application in gas separation and storage technologies. <br></p>
