Can electro-capillary peeling be used for reusing soft materials?

This work shows the great potential of the electro-capillary peeling method to provide a simple way to transfer films and facilitates valid avenues for reusing soft materials. Current methods for thin film peeling suffer from limitations because of complicated preparations and the limitations of applied films.

Can electro-capillary peeling be used to detach a thin film?

For some thin films vulnerable to water, the electro-capillary peeling method could be applied to detach them using organic solvents, such as alcohol, acetone, and glycerol solutions (Supplementary Fig. 13). Finally, the electro-capillary peeling method could also easily detach fully attached micro/nanofilms due to the special peeling mode.

What is electro-capillary peeling?

Unlike the complicated modification of the bonding layer and applied film restriction of capillary peeling, the electro-capillary peeling method is an active detaching approach with a direct current (DC) supply power and can be applied to a broad range of films, even in hydrogels of high adhesion stress.

How to Peel PDMS film from ITO glass?

Ultimately, the experimental setup and the critical peeling voltage indicated that the electro-capillary peeling method could easily peel the PDMS film (thickness of 100 μm and elastic modulus of 1.0 MPa) from the ITO glass by using a 0.7 V power supply (corresponding to Figs. 1, 4).

Is electro-capillary peeling suitable for stronger interface detachment?

It was inferred from the working mechanism that the applied voltage could be increased to detach thin film with a strong bonding layer, indicating that the electro-capillary peeling method would be suitable for stronger interface detachment than the capillary peeling approach.

Does electro-capillary peeling remove wet adhesion?

The water blister and peeling test presented that the electro-capillary peeling method readily detaches the film of the wet adhesion from 37 to 3656 mJ m ‒2 (Supplementary Tables 1 – 3).
