用红外光谱法（FI-IR）研究了橡胶微观结构、炭黑表面基团对橡胶/炭黑的界面相互作用的影响。研究表明,炭黑加入后各分子基团的振动均发生红移。炭黑与富电子的分子链相互作用大,即天然橡胶（NR）〉丁基橡胶（BR）〉丁苯橡胶（SBR）〉丁腈橡胶（NBR）;对侧基的影响小于对主链的影响。极性基团丙烯腈含量（ACN）增加,除ν（C≡N）外碳链上的其它基团均发生蓝移,且支链上双键基团所受影响最大。炭黑加入后,减弱了ACN含量增加对链段间作用力的影响,随ACN含量增加各基团蓝移较纯胶的小。门尼黏度仅影响δCH2的振动峰位。
The influence of rubber microstructure, carbon black surface groups on interface interaction of rubber- carbon black composite was studied by infrared spectrometry （FI-IR）. After carbon black mixed, the absorption bands of rubber groups show red shift obviously. Carbon black has stronger interaction with electron-rich molecules chain, namely nature rubber （NR） 〉 butadiene rubber （BR） 〉 styrene butadiene rubber （SBR） 〉 nitrile rubber （NBR）. The influence on side chain groups is smaller than on the main chain ones. The groups except v（C-~N） show blue shift with acrylonitrile （ACN） content increasing. ACN content affects the absorption band of 8CH（1,2） most. The interfacial interaction weakens the influences of ACN content on rubber molecular groups, which makes the blue shift smaller than NBR. The Mooney viscosity only affects the absorption band of 3CH2.
