By Bhavna KavetiSep 8 2022Reviewed by Susha Cheriyedath, M.Sc. Ordered topography is a desirable property in smart wearables and biological electronics that utilize brush shearing technology . Despite its facile operation and large-scale ability, BST could not realize efficient nanomaterial processing due to size mismatch between microscale brushed units and nanoscale building blocks.
Thus, the present work showcased the advantages of the NBST strategy in realizing the assembly of various nanomaterials to meet the challenges in printed electronics, nano bioengineering, and many more. BST has advantages, including roll-to-roll compatibility, high throughput, and minimal material waste. The technique’s potential to manufacture various functional dispersion or solutions led to developing two-dimensional nanomaterials dispersion and perovskite solution.
Previous reports mentioned that reducing the width of the trench generates a strong unidirectional force field facilitating the alignment of 1D nanomaterials. Consequently, a hypothesis was drawn based on nanoscale gaped brush configurations that could tune the direction of various nanomaterials.
