A new analogue of polydopamine (PDA), i.e., polyhydroquinone (PH₂Q), was polymerized and its surface chemistry was studied by different ways of characterization. PH₂Q was produced by the self-polymerization of H₂Q mediated by dissolved oxygen, and the self-polymerization process was strongly dependent on the type and the pH value of the buffer solutions. PH₂Q can not only achieve surface hydrophilization of different substrates like polyethylene terephthalate (PET) film, graphite strip, C₁₂SH/Au and wax slice, but also possess several unique properties like reversible adsorption, good solubility and low cost. These properties made PH₂Q an ideal polymeric modifier for the noncovalent functionalization of some nanomaterials. By simply grinding with PH₂Q, pristine multi-walled carbon nanotubes (MWNTs) can be readily dispersed in water with high solubility and good stability. The resulting MWNT–PH₂Q composite exhibited excellent electrochemical performance, which was employed for the simultaneous determination of dopamine (DA) and uric acid (UA).

聚合了一种新的聚多巴胺（PDA）类似物，即聚氢醌（PH ₂ Q），并通过不同的表征方法研究了其表面化学。PH ₂ Q是由溶解氧介导的H ₂ Q自聚合产生的，自聚合过程在很大程度上取决于缓冲溶液的类型和pH值。PH ₂ Q不仅可以实现聚对苯二甲酸乙二醇酯（PET）薄膜，石墨带，C ₁₂ SH / Au和蜡切片等不同基材的表面亲水化，而且还具有可逆吸附，良好的溶解性和低成本等多种独特性能。这些特性使PH ₂Q是某些纳米材料非共价官能化的理想聚合物改性剂。通过简单地用PH ₂ Q研磨，原始的多壁碳纳米管（MWNT）可以很容易地以高溶解度和良好的稳定性分散在水中。所得的MWNT-PH ₂ Q复合材料表现出优异的电化学性能，可用于同时测定多巴胺（DA）和尿酸（UA）。
