WebMost nanoporous materials can be classified as bulk materials or membranes. Activated carbon and zeolites are two examples of bulk nanoporous materials, while cell membranes can be thought of as nanoporous membranes. A porous medium or a porous material is a material containing pores (voids). WebThe nanoporous materials were characterized by small-angle X-ray scattering, scanning electron microscopy, and N 2 adsorption experiments. The nanoporous monoliths were thermally stable up to about 130 °C and exhibited remarkable mechanical strength that was comparable to pure polyDCPD. Supporting Information
