The capillary transfer technology presented here represents a powerful approach to transfer soft films from surface of liquid onto a solid substrate in a fast and defect-free manner. The fundamental theoretical model and transfer criteria validated with comprehensive experiments and finite element analyses, for the first time provides a quantitative guide and optimization for the choice of material systems, operating conditions and environments for scalable on-demand transfers with high yield. The intrinsically moderate capillary transfer force and externally selectable transfer direction offer robust capabilities for achieving deterministic assembly and surface properties of structures with complex layouts and patterns for potentially broad applications in the fabrication of flexible/stretchable electronics, surface wetting structures and optical devices. Integration of this technology with other advanced manufacturing technologies associated with material self-assembly, growth and layout alignment represents promising future topics and would help create emerging new manufacturing technologies that leverage unique fluidity of liquid environments.
