Abstract
The present invention is an assembly layer for a flexible device. The assembly layer is derived from precursors that include an alkyl(meth)acrylate ester having 1 to 24 carbon atoms in the alkyl group and a free-radical generating initiator. Within a temperature range of between −30° C. to 90° C., the assembly layer has a shear storage modulus at a frequency of 1 Hz that does not exceed 2 MPa, a shear creep compliance (J) of at least 6×10″1/Pa measured at 5 seconds with an applied shear stress between 50 kPa and 500 kPa, and a strain recovery of at least 50% at at least one point of applied shear stress within the range of 5 kPa to 500 kPa within 1 minute after removing the applied shear stress. In a preferred embodiment, the flexible device is a flexible electronic display.
