以过氧化苯甲酰(BOP)为模板分子，甲基丙烯酸(MAA)为功能单体，乙二醇二甲基丙烯酸酯(EGDMA)为交联剂，偶氮二异丁腈(AIBN)为引发剂，采用热聚合法在多壁碳纳米管(MWNTs)表面制备印迹聚合物(MWNTs-MIPs)。采用红外和热重分析等技术对聚合物结构进行表征。采用液相色谱考察该分子印迹聚合物对过氧化苯甲酰的吸附特性。结果表明该印迹聚合物对过氧化苯甲酰表现出特异性吸附，该印迹聚合物对模板分子存在一种结合位点，其最大表观结合量为56.20 µmol/g。该印迹聚合物成功应用于固相萃取富集面粉中微量过氧化苯甲酰，浓度富集因子为526。
A novel surface imprinting material based on multi-wall carbon nanotubes (MWNTs) was successfully synthesized with a precipitation polymerization method using benzoyl peroxide (BPO) as template, methacrylic acid (MAA) as the functional monomer, ethylene glycol dimethacrylate (EGDMA) as the cross-linker, 2, 2′-azobis-isobutyronitrile (AIBN) as the initiator. The molecularly imprinted polymers (MIPs) based on the surface of MWNTs was characterized by IR and differential thermal analysis (DTA). The adsorption amount of benzoyl peroxide by MIPs was measured by high performance liquid chromatography (HPLC) and equilibrium binding experiment. The results showed that a kind binding site is observed for the imprinted polymers to the benzoyl peroxide (BPO) with the maximum apparent binding constant 56.20µmol/g. By using as solid-phase extraction materials, the imprinted polymers extracted benzoyl peroxide from flour successfully with the concentration enrichment factor of 526.
