氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)(grapheneoxide)是(shi)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)的(de)(de)(de)(de)氧(yang)(yang)(yang)化(hua)物，其(qi)顏(yan)色(se)(se)為棕黃(huang)色(se)(se)，市面上常見的(de)(de)(de)(de)產(chan)(chan)品(pin)有粉末(mo)狀(zhuang)、片(pian)(pian)狀(zhuang)以(yi)及溶(rong)液(ye)狀(zhuang)的(de)(de)(de)(de)。因經(jing)氧(yang)(yang)(yang)化(hua)后，其(qi)上含氧(yang)(yang)(yang)官能團(tuan)增多而使性(xing)質(zhi)較石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)更加活潑(po)，可經(jing)由各種與(yu)含氧(yang)(yang)(yang)官能團(tuan)的(de)(de)(de)(de)反應而改善本身(shen)性(xing)質(zhi)。氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)薄片(pian)(pian)是(shi)石(shi)(shi)墨(mo)(mo)(mo)粉末(mo)經(jing)化(hua)學(xue)氧(yang)(yang)(yang)化(hua)及剝離后的(de)(de)(de)(de)產(chan)(chan)物，氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)是(shi)單一的(de)(de)(de)(de)原子(zi)層，可以(yi)隨時在(zai)(zai)橫向尺寸(cun)上擴展(zhan)到數十微(wei)米。因此，其(qi)結構跨越(yue)了一般化(hua)學(xue)和材料(liao)(liao)科學(xue)的(de)(de)(de)(de)典型尺度。氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)可視為一種非傳統型態的(de)(de)(de)(de)軟性(xing)材料(liao)(liao)，具有聚合(he)物、膠(jiao)體、薄膜，以(yi)及兩(liang)性(xing)分子(zi)的(de)(de)(de)(de)特性(xing)。氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)長(chang)久以(yi)來被(bei)視為親水(shui)(shui)性(xing)物質(zhi)，因為其(qi)在(zai)(zai)水(shui)(shui)中具有優越(yue)的(de)(de)(de)(de)分散性(xing)，但是(shi)，相關(guan)實驗結果顯示，氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)實際(ji)上具有兩(liang)親性(xing)，從石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)薄片(pian)(pian)邊緣(yuan)到**呈現親水(shui)(shui)至疏(shu)水(shui)(shui)的(de)(de)(de)(de)性(xing)質(zhi)分布(bu)。因此，氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)可如同界面活性(xing)劑(ji)一般存在(zai)(zai)界面，并降(jiang)低界面間(jian)的(de)(de)(de)(de)能量(liang)。其(qi)親水(shui)(shui)性(xing)被(bei)認(ren)知。氧(yang)(yang)(yang)化(hua)石(shi)(shi)墨(mo)(mo)(mo)烯(xi)(xi)的(de)(de)(de)(de)精(jing)確結構還無法得到確定。
