Going beyond the state-of-the-art, here we propose to make nanomembranes which are ultimately thin, comprising angstrom-scale pores/channels, with minimal defects. Angstrom channels have significance in many natural phenomena such as capillary rise in trees, gas condensation in rock sediments, in ion channels/pumps etc. To mimic the functioning of natural systems, several artificial pores/channels of similar sizes are being engineered synthetically. Such pores can be used in many technologies including filtration, molecular separation, desalination, DNA sequencing to name but a few. The key aim of the project is to develop methods to produce robust porous nanomembranes on a large scale by slicing porous and layered materials. While there are several excellent porous and layered materials which have angstrom-scale channels, there are several bottlenecks to incorporate them into membranes to utilize their full potential in applications such as filtration, ion sieving, power generation etc. Moreover, when such porous materials are cast into membranes, the pore clogging, fragility, control on the channel length and leaky paths are also major issues. Here we address all these problems by using a simple and robust technique for manufacturing nanomembranes from slicing the pristine materials embedded in a resin matrix. We propose a robust, scalable technique to make ultrathin membranes with nanomaterials, which are useful for molecular separation, osmosis, fuel cells, supercapacitors etc.The research will be carried out in University of Manchester, and National graphene Institute. Training of personnel in precise nano-manufacturing which is acquired though this project, is of immense importance to many areas of academic and industrial by underpinning fundamentals concepts in physics, materials chemistry, and nanofluidics, catering to the continually growing need for well-trained research personnel with appropriate technical knowledge, skills and expertise. This cohesive and innovative approach will develop new tools essential for precise assembly of porous materials in membranes.

超越了最先进的东西，在这里我们建议制造最终薄的纳米膜，其中包括易盎司的毛孔/通道，并具有最小的缺陷。在许多自然现象中，埃斯特罗姆通道具有显着性，例如树木的毛细血管升高，岩石沉积物中的气体冷凝，离子通道/泵等，以模仿天然系统的功能，几种类似尺寸的人造毛孔/通道正在合成。这样的毛孔可用于许多技术，包括过滤，分子分离，海水淡化，DNA测序的名称。该项目的主要目的是开发方法，通过切片和分层材料通过切片和分层材料来大规模生产强大的多孔纳米膜。虽然有几种具有备用尺度频道的多孔和分层材料，但有几种瓶颈将它们纳入膜中，以利用它们的全部潜力，例如过滤，离子筛分，发电等。此外，当这些多孔材料被施加到膜中时，孔隙堵塞，毛孔堵塞，脆性，脆弱，对频道长度和泄漏的路径也要漏洞，主要是问题。在这里，我们通过使用一种简单而强大的技术来解决所有这些问题，从而从切片中嵌入树脂基质中的原始材料来制造纳米膜。我们提出了一种可靠，可扩展的技术，以制造具有纳米材料的超薄膜，该膜对于分子分离，渗透，燃料电池，超级电容器等有用。这项研究将在曼彻斯特大学和国家石墨烯研究所进行。通过该项目获得的精确纳米制造的人员进行培训，这对于许多学术和工业领域而言非常重要，这对于物理学，材料化学和纳米流利学方面的基础概念构成了基础概念，可满足对具有适当的技术知识，技能，技能和专业知识的良好培训研究人员的不断增长的需求。这种具有凝聚力和创新的方法将为精确组装膜中的多孔材料的精确组装而开发新的工具。
