style="text-indent:25px">氟碳表面活性劑的獨(dú)特性質(zhì)直接與氟碳鏈相關(guān)，更進(jìn)一步講是取決于氟元素的獨(dú)特性質(zhì)。簡而言之，相對于其他表面活性劑，氟碳表面活性劑較為明顯的特點(diǎn)是：高效、穩(wěn)定，即高表面活性，高熱力學(xué)和化學(xué)穩(wěn)定性。氟元素是電負(fù)性較強(qiáng)的元素，它具有高氧化勢、高電離能，這種特性一方面造成氟—碳鍵（F—C）鍵能高（實(shí)際上氟—碳鍵是已知鍵能較高的共價(jià)鍵），因而氟碳鏈結(jié)構(gòu)遠(yuǎn)比碳?xì)浣Y(jié)構(gòu)穩(wěn)定；另一方面氟原子非常難以被極化，使氟碳鏈極性比碳?xì)滏溞?。正是因?yàn)檫@種低極性，使氟碳鏈?zhǔn)杷饔眠h(yuǎn)比碳?xì)滏湉?qiáng)烈（其實(shí)，低極性不但使氟碳鏈?zhǔn)杷疫€疏油—這里油是指碳?xì)漕惢衔铮?；另外，低極性又導(dǎo)致氟碳鏈相互間作用力弱。這二個(gè)因素共同作用使得氟碳表面活性劑分子在水溶液中有比其它表面活性劑分子更加強(qiáng)烈的傾向來脫離水溶液，在液/氣界面上定向聚集排列成分子膜，從而使其具有與其它表面活性劑所不同的二種特性；顏填料,助劑,樹脂,乳液,分散氟碳表面活性劑作為一種特種表面活性劑, 具有“三高, 兩憎”的特性。河北YM-318滲透劑</p><p style="text-indent:25px">YM-318可極大地提高鋪展系數(shù)，提高偶聯(lián)劑乳液體系潤濕性及滲透性，驅(qū)趕微氣泡。河北YM-318滲透劑</p><p style="text-indent:25px">在本質(zhì)上聚氧乙烯基或聚氧丙烯基的長短直接影響了分子中“過渡段”的長短，因此影響了氟碳表面活性劑的表面活性行為，這將在氟碳表面活性劑結(jié)構(gòu)特點(diǎn)章節(jié)中詳細(xì)討論。所以使用非離子氟碳表面活性劑可以選擇其極性基的長度以達(dá)到滿意的應(yīng)用效果。在說明非離子氟碳表面活性劑因其不存在離子狀態(tài)而穩(wěn)定的同時(shí)，還必須指出，這一類氟碳表面活性劑的極性基部分都是普通的碳?xì)浠衔锝Y(jié)構(gòu)，且往往有相當(dāng)?shù)拈L度，所以與羧酸鹽或磺酸鹽極性基相比，其化學(xué)穩(wěn)定性要差一些，因而限制了非離子氟碳表面活性劑在強(qiáng)氧化介質(zhì)中的使用。河北YM-318滲透劑</p><p
