一般的色素炭黑表面光滑，聚集體分布比較狹窄。但是高結(jié)構(gòu)色素炭黑聚集體外觀是繁雜的支鏈狀，這樣會(huì)更加豐富多能。溫度緩慢增大的情況下，高結(jié)構(gòu)色素炭黑表面氧化官能團(tuán)脫落，總酸含量降低，但是結(jié)合膠的含量卻在升高。 </p> <p> 比表面積跟色素炭黑的色散自由能是正比關(guān)系的，通過(guò)用溫度和氧化處理的結(jié)果不同，從而得出含氧官能團(tuán)不是吸附橡膠的活性中心。碳黑（carbon black），又名炭黑，是一種無(wú)定形碳。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;
