Abstract: A method comprises providing a polymer. The polymer is heated to a first predetermined temperature so as to liquefy the polymer. The liquefied polymer is formed into a polymer fiber. The polymer fiber is cross-linked to form a cross-linked polymer fiber comprising a polymer network by at least one of cooling the polymer fiber to a second predetermined temperature lower than the first predetermined temperature or exposing the polymer fiber to a cross-linking stimulus, the cross-linked polymer fiber capable of being decross-linked by heating to a third predetermined temperature above a characteristic decross-linking temperature of the polymer.
