Hydrophobic and oleophobic coatings, methods of making same and uses of same

A method of forming an oleophobic and/or hydrophobic layer disposed on a portion of, substantially all of, or all of one or more exterior surface(s) of a substrate, the method comprising:

• coating a portion of, substantially all of, or all of one or more of the exterior surface(s) of the substrate with an aqueous dispersion comprising a plurality of polymeric particles, wherein each individual polymeric particle comprises one or more oleophobic and/or hydrophobic polymer(s) and/or one or more oleophobic and/or hydrophobic copolymer(s), wherein the polymer(s) and/or the copolymer(s) comprise(s) one or more pendant group(s) comprising the following structure:
• wherein R1, R2, and R3 are independently at each occurrence chosen from alkyl groups, alkoxy groups, aryl groups, hydroxyl groups, halogen groups, substituted derivatives and analogs thereof, and —O—SiR′3 groups, wherein R′ is independently at each occurrence chosen from alkyl groups, aryl groups, and substituted derivates and analogs thereof, wherein, for at least one or more of the pendant group(s) of each of the polymer(s) and/or each of the copolymer(s), at least one of R1, R2, and R3 is independently at each occurrence chosen from the —O—SiR′3 groups,
• wherein L is a linking group, and
• wherein the pendant group(s) is/are independently at each occurrence covalently bonded to the polymer(s) and/or the copolymer(s) via one or more backbone(s) and/or one or more substituent group(s) of the polymer(s) and/or the copolymer(s);
• and
• wherein the oleophobic and/or hydrophobic layer is formed on a portion of, substantially all of, or all of one or more of the exterior surface(s) of the substrate;
• and
• optionally, curing the oleophobic and/or hydrophobic layer.
