Abstract (en)

[origin: WO2019152081A1] Some variations provide an anti-fouling segmented copolymer composition comprising: (a) one or more first soft segments selected from fluoropolymers; (b) one or more second soft segments selected from polyesters or polyethers; (c) one or more isocyanate species possessing an isocyanate functionality of 2 or greater, or a reacted form thereof; (d) one or more polyol or polyamine chain extenders or crosslinkers, or a reacted form thereof; and (e) a fluid additive selectively disposed in the first soft segments or in the second soft segments. Other variations provide an anti-fouling segmented copolymer precursor composition comprising a fluid additive precursor selectively disposed in the first soft segments or in the second soft segments, wherein the fluid additive precursor includes a protecting group. The anti-fouling segmented copolymer composition may be present in an anti-ice coating, an anti-bug coating, an anti-friction coating, an energy-transfer material, or an energy-storage material, for example.
