The invention relates to a self-assembled monolayer comprising fluoroalkyl chains F3C—(CF2)m—(CH2)n— of differing length, wherein m is an integer of from 3 to 36, n is an integer of from 0 to 40, and m in the longer fluoroalkyl chain is larger than m in the shorter fluoroalkyl chain by at least 2, preferably by at least 8. The molar ratio of the longer fluoroalkyl chains to the shorter fluoroalkyl chains is from 1:9 to 9:1.
