1. A hydrophobic surface coating, being formed on a surface of a substrate by a plasma-enhanced chemical vapor deposition method, with a crosslinking agent and one or more fluorinated alcohol compounds as a reaction gas raw material, wherein the crosslinking agent has the formula:

OG Complex Work Unit Chemistry
wherein R1, R2, R3, R5, R6 and R7 are selected from hydrogen, alkyl, aryl, halogen, haloalkyl, and haloaryl; j and k are integers from 0 to 10 and are not 0 at the same time; and R4 is a bond, —CO—, —COO—, an arylidene, an alicyclic alkylidene, or an aliphatic alkylidene substituted with hydroxy; or
wherein the crosslinking agent is selected from a group consisting of: one or more of glycidyl methacrylate, allyl glycidyl ether, 1,2-epoxy-4-vinylcyclohexane, 3-(2,3-epoxypropoxy)propylvinyldimethoxysilane, and enbucrilate.
