Circumventing wear and tear of adaptive porous materials

In our essay we bring to the attention of the material science community the importance of evaluating architectural damage made to porous materials in their prolonged usage. In the article, we present an overview of chemical, mechanical, and thermal origins of architectural damage (see image below) and provide general guidelines for its thorough assessment, prevention, and remediation, in order to inform the design of robust and durable porous materials.

In this exciting era of material science, the measuring and understanding of material properties often lag behind the rapid discovery of new materials and the implementation of their applications. Our essay contributes to addressing this fundamental challenge by presenting a systematic study of porous material based on their underlying physical and chemical behavior. 

In this way, we hope to initiate the discussion on architectural stability, and encourages readers to carefully characterize functional porous materials for a better understanding of the structure-property relationship. We aim to establish an interdisciplinary context that joins efforts from multiple fields together to bring the performance of functional porous materials from the nanometer scale to the macroscopic level.

Main origins of architectural damage formation in adaptive frameworks: defective adaptation to guest species (1.1a-c), irreversible adaptation to guest dynamics (1.2), destructive relaxation upon pore pressure increase (1.3), and localized thermal deterioration (1.4)
