    摘要: Poly fluorine-containing siloxane coatings having improved hydrophobic and oleophobic properties and solutions for creating such coatings are provided. In some embodiments, the coating includes a polymer having a plurality of Si—O—Si linkages; and at least two fluorine-containing moieties, each attached to at least one of the Si—O—Si linkages. Each fluorine-containing moiety independently includes a linking portion attached to a silicon of one of the Si—O—Si linkages, wherein the linking portion is of a formula selected from the group consisting of: —[CH2]a— where a is an integer from 1 to 10 and —[CH2]bCONH[CH2]c— where b and c are independently an integer from 0 to 10. Each fluorine-containing moiety also independently includes a fluorinated portion attached to the linking portion, wherein the fluorinated portion is selected from a fluorinated-alkyl group having 1-10 carbon atoms and a perfluoro-ether containing organic group.

    摘要: Composite phase change materials, methods for manufacturing composite phase change materials, and articles of clothing including composite phase change materials for temperature regulation are provided. In one example, a composite phase change material includes a cross-linked polyethylene glycol matrix and a phase change material filler. Each of the cross-linked polyethylene glycol matrix and the phase change material filler has a phase change temperature of from about 10 to about 60° C. Further, the composite phase change material has a latent heat of enthalpy greater than about 50 kJ/kg.
