Process for depositing by electrografting a strong adherent polymer coating onto an electrically conductive surface comprising the step of electrochemical grafting of an active monomer for forming a primer coating P onto the surface and having as general formula: X0 (meth)acrylate wherein X is either part of a preformed polymer or is an intermediate agent for polyaddition reaction or is an anchoring group for attachment of a molecule having at least one complementary reactive group. Such process allows formation of new primer by one-step electro-grafting of a macromonomer. Such process also allows further modification of an initial electrografted polymer to increase the coating thickness by the grafting-from technique. Such process also allows to graft onto the primer coating compounds like functional polymer, peptide, protein, oligonucleotide, dyes, drugs, anti-bacterian compounds.
用电接枝法在导电表面上沉积附着力强的聚合物涂层的工艺,包括在表面上接枝活性单体以形成底涂层 P 的电
化学接枝步骤,其通式为:X0 (甲基)
丙烯酸酯 其中,X 是预成型聚合物的一部分,或者是用于加成反应的中间体,或者是用于连接具有至少一个互补反应基团的分子的锚定基团。这种工艺可以通过一步电接枝大单体来形成新的引物。这种工艺还可以对初始电接枝聚合物进行进一步改性,以通过从接枝技术增加涂层厚度。这种工艺还可以将功能性聚合物、肽、蛋白质、寡核苷酸、
染料、药物、抗菌化合物等化合物接枝到引物涂层上。
