Abstract
The present disclosure provides, inter alia, a method of producing an outer layer material for forming into a structure and that comprises an entanglement having a hydrophobic polymer host and a hydrophilic guest, including in one embodiment the steps of: intermingling cloaked hydrophilic guest complexes with the hydrophobic host; crosslinking molecules of the guest with the guest; and performing a hydrolysis reaction.
