 Advanced Materials, In press 

 Dynamic Electrostatic Lithography is invented to dynamically generate various patterns on large-area and curved polymer surfaces under the control of electrical voltages. The shape of the pattern can be tuned from random creases and craters to aligned creases craters and lines, and the size of the pattern from millimeters to sub-micrometers.

Thank you, Shengqiang. Looking forward to talking with you next conference.

Excellent work Qiming. I see various applications, especially in accessibility. Would you like more information. Congratulations - Jorge Rosivan - Brazil]

Hi Jorge, thank you for  your interest in our paper. Dynamic Electrostatic lithography has a number of potential applications. Previous electrostatic lithography technology basically generate static patterns on flat and small surfaces, while our method can dynamically switch between different patterns to generate on-demand patterns on large-area curved surfaces. This technology potentially can be used in on-demand super-hydrophobicity, tunable adhesion, switchable optics, controlled drug release, anti-fouling coatings, and transfer printing. if you have any questions or concerns, feel free to let us know.
