We investigated the wrinkle formation on ion-beam (IB)-irradiated substrates coated with the thermoplastic elastomer styrene-b-isoprene-b-styrene (SIS) and demonstrate a relation of the wrinkle structure and the newly formed top layer induced by IB. IB irradiation led to polymer cross-linking on the surface, thereby forming a new skin layer, a finding which was supported by an X-ray photoelectron spectroscopy analysis, Young moduli calculated using force–distance curves, and time-of-flight secondary ion mass spectrometry depth profiling. The wrinkle wavelength increased according to the irradiation time, which indicates that the latter mainly increased the thickness of the cross-linking layer. The increase in the wrinkle wavelength varied from 420 to 670 nm by changing the IB irradiation time. In this paper, we present not only the expectation of wrinkle fabrication using our method but also the possibility of choosing diverse materials such as the thermoplastic elastomer SIS for fabrication of wrinkle structures.

一步离子束辐照在苯乙烯-b-异戊二烯-b-苯乙烯薄膜上形成皱纹结构

我们研究了在涂有热塑性弹性体苯乙烯-b-异戊二烯-b的离子束（IB）辐照的基材上的皱纹形成情况-苯乙烯（SIS）并证明了IB引起的皱纹结构与新形成的顶层之间的关系。IB辐照导致表面上的聚合物交联，从而形成一个新的表皮层，这一发现得到了X射线光电子能谱分析，使用力-距离曲线计算的杨氏模量以及飞行时间的二次离子的支持质谱深度分析。皱纹波长随着照射时间而增加，这表明后者主要增加了交联层的厚度。通过改变IB照射时间，皱纹波长的增加从420nm变化至670nm。在本文中，
