The invention relates a polyacrylate-polysilane block copolymer of general structure (I): wherein m and n independent of one another, are integers ranging from 2 to 4000; p is an integer ranging from0 to 5; q is an integer ranging from 1 to 5; R1 represents hydrogen, straight-chain or branched alkyl group having 1 to 4 carbon atoms; R2 represents hydrogen, straight-chain or branched alkyl group having 1 to 18 carbon atoms; R3 represents hydrogen, hydroxyl group, straight-chain or branched alkyl group having 1 to 4 carbon atoms, or an C6-C14 aryl group; L is a linking moiety representing amine(-NH-) group, amide (-C(O)NH-) group, urea (-NHC(O)NH-) group, urethane (-OC(O)NH-) group or methylene (-CH2-) group; R4, R5 and R6 independent of one another, represents hydrogen, straight-chain orbranched, alkyl group having 1 to 8 carbon atoms or polydimethylsiloxane group; and R7 represents hydrogen or methyl group.
