Graphene oxide (GO) was doped into four polymers films: Poly(methyl methacrylate) (PMMA), polystyrene (PS), polycarbonate (PC), and polyacrylonitrile (PAN). Following that, their optical limiting properties were investigated at 532 nm. In order to make GO hydrophobic, the lipophilic alkyl chains were connected to GO. The results showed that GO/PAN composite possesses better non-linear response than the other three composites at the same transmission (T ~ 59%). The reason were attributed to the thermal effect coming from high input fluence of laser, which improved the cross link density of PAN and further enhanced the interaction between the GO-ODA and PAN. Meanwhile, GO/PC and GO/PS had similar optical limiting property and GO/PMMA film gave the weakest optical limiting effect in our experiment.
氧化石墨烯（GO）被掺杂到四种聚合物薄膜中：聚甲基丙烯酸甲酯（PMMA）、聚苯乙烯（PS）、聚碳酸酯（PC）和聚丙烯腈（PAN）。随后，在532nm波长下研究了它们的光限幅性能。为了使GO具有疏水性，将亲脂性烷基链连接到GO上。结果表明，在相同透过率（T~59%）下，GO/PAN复合材料比其他三种复合材料具有更好的非线性响应。原因是激光高输入能量产生的热效应，提高了PAN的交联密度，进一步增强了GO-ODA与PAN之间的相互作用。同时，GO/PC和GO/PS具有相似的光限幅性能，而GO/PMMA薄膜在我们的实验中光限幅效果最弱。
