[1]Carboxylation treatment of multiwalled carbon nanotubes monitored by infrared and ultraviolet spectroscopies and scanning probe microscopy 使用AFM、FTIR、UV/Vis来分析和研究混合浓硝酸浓硫酸处理后MWNT的形态及处理的效果。 [2]Analyzing the quality of carbon nanotube dispersions in polymers using scanning electron microscopy 看题目就知道了吧！SEM观察CNT在基体中的分散情况。文章里面介绍的比较详细。 [3]Influence of dispersion states of carbon nanotubes on physical properties of epoxy nanocomposites 该文介绍了CNT不同分散程度对环氧树脂复合材料的流变学、机械性能、导电性、热性能的影响。用FESEM和TEM表征了CNT的分散情况。。。。 [4]General Strategies for Nanoparticle Dispersion 发表在Science 2006年3.24 VOL311 上的一篇文章，我还没来得及看。把摘要帖上来，大家自己看吧。 Traditionally the dispersion of particles in polymeric materials has proven difficult and frequently results in phase separation and agglomeration. We show that thermodynamically stable dispersion of nanoparticles into a polymeric liquid is enhanced for systems where the radius of gyration of the linear polymer is greater than the radius of the nanoparticle. Dispersed nanoparticles swell the linear polymer chains, resulting in a polymer radius of gyration that grows with the nanoparticle volume fraction. It is proposed that this entropically unfavorable process is offset by an enthalpy gain due to an increase in molecular contacts at dispersed nanoparticle surfaces as compared with the surfaces of phase-separated nanoparticles. Even when the dispersed state is thermodynamically stable, it may be inaccessible unless the correct processing strategy is adopted, which is particularly important for the case of fullerene dispersion into linear polymers.
