| 摘 要： | 利用三氯化钐(SmCl3)和二氯化钐(SmCl2)之间的单电子转移反应,以AIBN/SmCl3/乳酸作为反向原子转移自由基聚合(Reverse ATRP)的催化体系,在金属铜表面接枝聚离子液体刷,利用原子力显微镜(AFM)、X射线光电子能谱(XPS)、接触角测量、核磁共振和凝胶渗透色谱进行了表征.结果表明,在铜基底上成功地接枝了聚离子液体刷,且该聚合反应为"活性"/可控聚合,并通过对阴离子交换实现了亲疏水转换.

| Abstract: | Poly(ionic liquid)brushes are successfully grafted onto copper surface by a reverse atomic transfer radical polymerization with AIBN/SmCl3/lactic acid catalytic system and their surface wettability can be easily tuned by exchanging their counter anions.The X-ray photoelectron spectroscopy(XPS),atomic force microscope(AFM),static water contact angle measurements are used to monitor the variety of every step.Nuclear magnetic resonance(1H and 13CNMR)spectra,gel permeation chromatography(GPC) measurements revea... |
