摘要:

    普通的金屬防腐蝕涂層主要以鋅粉為防銹劑，但是大規(guī)模使用鋅粉容易產(chǎn)生重金屬污染，且鋅粉的的持續(xù)穩(wěn)定供應(yīng)也是令人關(guān)注的問題。導(dǎo)電高分子具有可逆的氧化還原特性，其金屬防腐能力已經(jīng)得到證實(shí)，因此導(dǎo)電高分子作為一種新型的防腐蝕材料受到人們的廣泛關(guān)注，并逐漸成為當(dāng)前腐蝕科學(xué)領(lǐng)域研究的一大熱點(diǎn)。其中聚苯胺以其優(yōu)異的環(huán)境穩(wěn)定性，合成簡(jiǎn)單，且價(jià)格相對(duì)較低，得到了特別的關(guān)注，相應(yīng)的防腐產(chǎn)品也已經(jīng)在德國(guó)、美國(guó)和中國(guó)等國(guó)部分商業(yè)化。本文系統(tǒng)總結(jié)了國(guó)內(nèi)外在聚苯胺防腐材料方面的基礎(chǔ)研究以及實(shí)際應(yīng)用進(jìn)展，重點(diǎn)探討了聚苯胺的獨(dú)特防腐機(jī)理，并對(duì)目前聚苯胺防腐材料存在的一些問題進(jìn)行了分析，指出聚苯胺很有希望成為新一代無毒無污染的防腐材料。��

Abstract:

    Common metal anticorrosion coatings are generally based on zinc powder; however, mass use of zinc based coating may cause heavy metal pollution in the media, and there also exists concern for the sustainable supply of zinc resource. Conducting polymers possess reversible redox performance, which enables them to be the new anticorrosion agents, and their anticorrosion performance has attracted intense attentions since late 1980s. Among them, polyanilines are of particular interest due to their environmental stability, easy synthesis, and relatively low cost. The prominent protection performance of polyaniline has been confirmed by numerous experiments, and some anticorrosion coating products have been developed in Germany, the United States and China. The progress in basic research and practical application of polyaniline as anticorrosion material is systemically reviewed, and the unique protection mechanisms of polyaniline are discussed in detail. Analyses are also made on the existing problems in polyaniline anticorrosion materials. It is concluded that the polyanilines are expected to be the new generation of anticorrosion material with nontoxic and pollution�瞗ree characteristics.��
