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.

聚二甲基硅氧烷（PDMS）的微流体发泡技术

多孔聚二甲基硅氧烷（PDMS）材料广泛应用于传感器、环境和组织工程等领域。我们介绍了一种制造多孔聚二甲基硅氧烷（PDMS）的微流体发泡方法，可精确控制孔径和分布。通过在发泡过程中调节气体压力，可以制造出具有均匀和梯度孔隙率的 PDMS 结构，从而实现机械性能的微调。这种微流体方法不仅简化了生产过程，还能合理设计具有定制机械特性的多孔 PDMS。
