Abstract: Foldable apparatus comprise a plurality of first portions and at least one second portion positioned between a corresponding adjacent pair of first portions of the plurality of first portions. Each second portion of the at least one second portion comprises a maximum Young’s modulus ranging from about 500 times to about 500,000 times less than a minimum Young’s modulus of the corresponding adjacent pair of first portions. In some embodiments, the at least one second portion comprises at least five second portions. In some embodiments, each second portion of the at least one second portion comprises a thickness ranging from about 10 micrometers to about 250 micrometers. In some embodiments, each first portion comprises a first neutral plane and each second portion comprises a second neutral plane. In some embodiments, an apparatus bend force ranges from about 0.5 times to about 1 times a total bend force.

Abstract: Polymer-based portions comprise an index of refraction ranging from about 1.49 to about 1.55. In some embodiments, the polymer-based portion comprises the product of curing 45-75 wt % of a difunctional urethane-acrylate oligomer with 25-55 wt % of a difunctional cross-linking agent and optionally a reactive diluent. In some embodiments, the polymer-based portion comprises the product of curing 75-100 wt % of a reactive diluent and optionally one or more a difunctional urethane-acrylate oligomer and/or a difunctional cross-linking agent. Adhesives comprise an index of refraction ranging from about 1.49 to about 1.55. In some embodiments, the adhesive comprises the product of heating 10-35 wt % of a silane-hydride-terminated siloxane and 65-90 wt % of a vinyl-terminated siloxane. In some embodiments, the adhesive comprises the product of irradiating a thiol-containing siloxane and a photo-initiator with at least one wavelength of light that the photo-initiator is sensitive to. Foldable apparatus can comprise the polymer-based portion and/or adhesive.
