具有褶皱导电路径的本征体弹性导体用于柔性电磁屏蔽和肿瘤消融(英文)
发布时间:2022-08-10 14:46
弹性导体在可穿戴电子设备和软机器人中至关重要.理想的本征弹性体导体在大形变下显示出均匀的三维导电网络结构和稳定的电阻变化.其面临的一个挑战是,由于体弹性导体在形变下导电路径断开,电阻变化很大.我们的策略是将具有互连微孔的泡沫进行预拉伸,通过碳纳米管在微孔表面自组装形成导电层,随后释放预应变,从而在导电网络中引入褶皱结构.在拉伸过程中,褶皱和微孔的变形都有助于电阻的稳定(在70%应变下电阻变化2.0%).微观结构和有限元分析表明,由于导电层中的缺陷,可以获得不同形貌的二维褶皱结构.我们展示了其在全方位电气互连、可拉伸电磁屏蔽和电热肿瘤消融方面的应用.
