Uniform surface wrinkling has attracted broad attention with its potential applications in stretchable electronics, optics and templating. However, engineering wrinkles with controlled defects still needs to be explored due to the lack of evaluation of fabrication parameters. Taking the advantage of orthogonal experiment, the influence of oxygen plasma treatment power, time, pressure and pre-strain ratio was explored for controlling the crack formation during Polydimethylsiloxane (PDMS) wrinkling. Among, plasma power has the greatest contribution on crack density, while pressure and time have relatively few influence, providing an insight for fabricating crack-free surface micro- and nanostructures.
