Triboelectric nanogenerator (TENG) devices with high robustness are promising in collecting powerful energy. In this study, highly elastic and pressure-resistance sponge fabricated TENG capable of adapting to high strength impact in land and water transportation and scalable for any shape is demonstrated for harvesting wave energy and mechanical energy. The polydimethylsiloxane sponge prepared by sacrificial template method has interconnected network and large size ratio of cavity-wall suitable for contact and separation. The operation modes of self-contact and extra-contact collaborating with MXene in electron transfer provide options for different operating conditions. The polydopamine-MXene modification of the sponge enables higher output due to the combination of the electronegativity, excellent adhesion, and antioxidant ability. Sponges are used to collect mechanical energy and applied for TENG-powered cathodic protection, making the 304 stainless steel (304 SS, Φ = 2 mm) electrode enter a thermodynamic stable state. What's more, the work also tries the universal strategies of program monitoring wave in the water tank and harvests the mechanical energy created by cars and passers-by, which enrich the applications of sponge TENG.

用于从陆地和水上运输中收集能量的柔性海绵纳米发电机

具有高鲁棒性的摩擦纳米发电机（TENG）装置在收集强大能量方面很有前景。在这项研究中，高弹性和耐压海绵制造的TENG能够适应陆地和水上运输中的高强度冲击，并且可扩展为任何形状，用于收集波浪能和机械能。牺牲模板法制备的聚二甲基硅氧烷海绵具有互连的网络和较大的腔壁尺寸比，适合接触和分离。自接触和外接触配合MXene进行电子转移的操作模式为不同的操作条件提供了选择。海绵的聚多巴胺-MXene改性由于结合了电负性、优异的附着力和抗氧化能力，可实现更高的输出。利用海绵收集机械能，并应用于TENG驱动的阴极保护，使304不锈钢（304 SS，Φ = 2 mm）电极进入热力学稳定状态。此外，该工作还尝试了程序监测水箱中的波浪以及收集汽车和路人产生的机械能的通用策略，丰富了海绵TENG的应用。
