The invention relates in various embodiments to a composite useful as e.g. a medical implant device, and a method of treating fouling, including biofouling as may occur on an implant. The composite comprises a matrix phase and a patterned phase that comprises an energetically activatable wire intermixed with the matrix phase, the wire when energetically activated, which includes thermal activation, causes modification of at least a portion of the matrix phase to treat fouling that might otherwise occur. The method of treating biofouling may be practiced on a patent while the medical implant of the invention is in situ.
