Abstract: A porous material includes a polyhexahydrotriazine material. Pores in the porous material can be of various sizes including nanoscale sizes. The porous material may be used in a variety of applications, such as those requiring materials with a high strength-to-weight ratio. The porous material can include a filler material dispersed therein. The filler material can be, for example, a particle, a fiber, a fabric, or the like. In some examples, the filler material can be a carbon fiber or a carbon nanotube. A method of making a porous material includes forming a resin including a polyhemiaminal or polyhexahydrotriazine component and a polythioaminal component. The resin can be heated to promote segregation of the components into different phases with predominately one or the other component in each phase. Processing of the resin after phase segregation to decompose the polythioaminal component can form pores in the resin.

Abstract: The present invention generally relates to porous membranes and other porous articles. In one aspect, the present invention is generally directed to porous membranes and other articles that have a pore size comparable to feature sizes of the extracellular matrix. Such articles may be useful, for example, for tissue engineering (e.g., as a substrate for culturing cells), as a filter, or for other applications. In some cases, the membranes may be formed from biocompatible and/or biodegradable materials. In some embodiments, such membranes may be formed using solvent evaporation induced self-assembly (EISA) techniques, although other techniques may be used in other embodiments. Still other aspects of the present invention are directed to methods of using such articles, kits involving such articles, and the like.
