Abstract
The current modification of polydimethylsiloxane (PDMS) substrates via oxygen plasma treatment causes surface cracks. Here, we demonstrate a method to prevent crack formation by chemical treatment. Chemical modification renders the surface hydrophilic for several days and is effective in preserving the elasticity of the PDMS surface at the nanoscale level.
摘要
目前通过氧等离子体处理对聚二甲基硅氧烷（PDMS）基底进行的改性会导致表面出现裂纹。在这里，我们展示了一种通过化学处理来防止裂纹形成的方法。化学改性使表面在几天内亲水，并有效地保持 PDMS 表面在纳米尺度的弹性。
