Abstract
Porous polydimethylsiloxane (PDMS) materials are widely used in areas including sensors, environment and tissue engineering. We presented a microfluidic foaming method for fabricating porous PDMS, offering precise control over pore size and distribution. By adjusting gas pressure during the foaming process, PDMS structures with both uniform and gradient porosity were created, enabling fine-tuning of mechanical properties. The microfluidic approach not only simplifies the production process but also allows for the rational design of porous PDMS with customized mechanical characteristics.
