The present invention is an optically clear, curable adhesive including a polyvinylbutyral, a polyurethane (meth)acrylate, and a photoinitiator. The polyvinylbutyral has a dynamic viscosity of between about 9 and about 13 mPa.Math.s and a polyvinyl alcohol weight percent of less than about 18%. The polyurethane (meth)acrylate includes the reaction product of a diol, at least one diisocyanate, and a hydroxyfunctional (meth)acrylate or an isocyanatofunctional (meth)acrylate. When the optically clear, curable adhesive is placed between two transparent substrates and made into a laminate, the laminate has a haze of less than about 6%, a transmission of greater than about 88% and an optical clarity of greater than about 98% when cured. The optically clear, curable adhesive also has a peel adhesion of at least about 100 g/cm based on ASTM 3330 when cured.

An adhesive material that provides fast and robust adhesion on wet surfaces, where the adhesion formed is detachable on-demand. The adhesive material is formed of one or more hydrophilic polymers or copolymers grafted with one or more amine coupling groups via a plurality of cleavable physical bonds and/or cleavable covalent bonds and one or more cross linkers. Application of the adhesive material on a wet surface causes the adhesive material to absorb liquid to thereby swell the adhesive material to form a layer of hydrogel, resulting in the formation of temporary crosslinks followed by covalent crosslinks with the surface. Introducing a triggering agent cleaves the cleavable physical bonds and/or cleavable covalent bonds to allow for non-traumatic detachment of the adhesive material from the surface.

A structural color coating based on Mie scattering of high-refractive index microspheres has the following components in parts by mass: 5 to 20 parts of nano microspheres having a highly uniform particle size and a theoretical refractive index greater than 1.7, 75 to 90 parts of dispersion liquid, 0.1 to 5 parts of a surfactant, and 1 to 5 parts of an adhesive. The structural color coating forms a local microcosmic ordered, macroscopic long-range disordered structural film by means of spraying coating, blade coating, brushing coating, roll coating or dip-coating; the matrix is glass, metal, textile, ceramic, plastic or paper; the surfactant is sodium dodecyl benzene sulfonate, cetyl sodium sulfate, stearic acid, or sodium stearate; the nano microsphere is at least one of ZnS, ZnO, CdS, Cu.sub.2O, CaS, CuS, Cu.sub.2S, TiO.sub.2, ZrO.sub.2 or CeO.sub.2; the particle size of the nano microspheres ranges from 200 to 500 nm.

This invention provides parasitic millirobots that can effectively adapt to an unstructured environment and coherently interact with diverse objects in order to fulfil various application needs. Particularly, a minimalist millirobot construction strategy by splashing composited agglutinate magnetic spray (M-spray) is adopted, which is capable of self-turning multifarious milli-/centi-objects into parasitic millirobots on-demand. Through taking full advantage of the objects' inherent structure and a covered thin drivable film, the M-spray demonstrates superior handling (from 1-D to 3-D structures) and loading capabilities (up to thousand-fold and hundred-fold of its volume and weight, respectively) while with neglectable size increment (as low as 1%) to target. Moreover, benefitting from peculiarities of online reprogramming and controllable disintegration, the parasitic millirobots can rewrite its locomotion mode according to the task and disintegrate themselves after mission accomplished, offering high adaptivity and compatibility for in vivo biomedical applications. Methods for conversion and fabrication thereof are also provided.
