Recent Progress in Fabrication and Application of Polydimethylsiloxane Sponges


Owing to their structural advantages over bulk polydimethylsiloxane (PDMS), porous 3D substrates, also known as PDMS sponges, possess immense potential in energy generation, transport and storage, absorption, separation, photocatalysis, wearable electronics and life science applications, extensive effort has been devoted to the design and synthesis of porous PDMS sponges. Key to excellent performance in high-value applications is deep knowledge of the beneficial aspects of porosity, structure and morphology towards a specific application. Several new fabrication routes for PDMS sponges as well as novel applications were unraveled recently. Therefore, this review focuses on the advances in the field of PDMS sponge fabrication and PDMS sponge application since 2011. After a concise introduction, including mentioning of benefits of PDMS over other materials, the synthesis/fabrication strategies of PDMS sponges are presented and their assets and drawbacks are concisely discussed. A summary of the potential fabrication procedures will be beneficial for those entering the field as it gives a quick overview of the feasible applications of a PDMS sponge fabricated with a specific method. Afterwards, the different high-value applications of PDMS sponges is given in conjunction with specific and detailed examples for all abovementioned applications. In this regard, it is also hinted, which fabrication method is beneficial for the application at hand. Finally, the recent advances in the fabrication and application of PDMS sponges is summarized and issues like surface functionalization and pore size limitation, which are impeding reasonable future applications. We envision that this review is helpful to those entering the field as well as experienced researchers needing quick access to recent literature, giving new stimuli for the development of novel porous materials.
