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.

A sheet material for use as a dissolvable decal comprises a dissolvable paper or polymer layer whose dissolvability in water is enhanced using a temporary water barrier. In one embodiment, the sheet material comprises a dissolvable paper stock layer coated with the temporary water barrier layer in the form of an acrylate polymer. To create the decal, one or more ink layers are applied, either on top of the temporary water barrier, or between the temporary water barrier and a top face of the dissolvable paper stock. The sheet material also comprises a removable release liner comprising a sheet with a silicone release coating on one side. In use, the paper/plastic liner is removed and the resulting decal is then positioned on a vehicle. The decal remains on the vehicle, but it is ultimately removable under high pressure water conditions.

A method conceals optical defects in surfaces. The method includes: obtaining a digital image by a digital optical recording the optical defect and a surrounding surface; obtaining an imitation of the surface in a region of the at least one optical defect by image processing of the digital image; printing a mirror-inverted, true-to-scale representation of the surface imitation onto a transfer film; soaking the transfer film; applying an activator onto a the transfer film or onto the surface; aligning the transfer film onto the surface so that the surface imitation on the transfer film coincides with the optical defect on the surface; pressing the transfer film onto the surface; peeling the transfer film from the surface; pressing on the ink remaining on the surface; and after complete drying of the activator and of the ink: applying a protective layer onto the surface imitation.

An eco-friendly activator-free water transfer printing film includes a water-based modified acrylic copolymer resin layer set on a superabsorbent film and made of a water-based modified acrylic copolymer resin which is formed by acrylic copolymer emulsion, polyvinyl alcohol (PVA) resin and polyvinylpyrrolidone (PVP) resin and provided crosslinking an end surface with the water-based modified acrylic copolymer resin layer after another end surface of the superabsorbent film absorbs water and becomes softened; and an information body set on the water-based modified acrylic copolymer resin layer; so that the present invention is simply set on a water surface to crosslink the superabsorbent film with the water-based modified acrylic copolymer resin layer to produce the adhesiveness of the water-based modified acrylic copolymer resin layer without using any activator.
