A blend of low molecular azo glass (AZOPD) and polystyrene (PS) were used for the systematic investigation of photo-induced stretching and recovery of nanoimprinted structures. For this purpose, light and heat was used as recovery stimuli. The AZOPD/PS microstructures, fabricated with thermal nanoimprint lithography (tNIL), comprises three different shapes (circles, crosses and squares) and various concentrations of AZOPD fractions. The results show a concentration-dependent reshaping. Particularly the sample with 43 w-% of the AZOPD fraction have shown the best controllable recovery for the used parameters. A possible explanation for shape recovery might be the stabilizing effect of the PS-matrix.
将低分子偶氮玻璃(AZOPD)和聚苯乙烯(PS)混合,用于系统研究纳米压印结构的光致拉伸和恢复。为此,使用光和热作为恢复刺激。通过热纳米压印光刻(tNIL)制造的AZOPD/PS微结构包括三种不同形状(圆形、十字形和方形)以及不同浓度的AZOPD组分。结果表明存在浓度依赖性的重塑。特别是AZOPD组分含量为43重量%的样品在所使用的参数下显示出最佳的可控恢复。形状恢复的一个可能解释可能是PS基体的稳定作用。
