顺磁共振和紫外光谱法研究SDS-PEO体系的相互作用

合成更疏水的自旋探针 4羰基 2， 2， 6， 6四甲基哌啶氮氧自由基 2， 4二硝基苯腙 .用顺磁共振（ ESR）和紫外光谱法研究了十二烷基硫酸钠（ SDS） 0.5％ (w，质量分数 )聚氧乙烯（ PEO）体系的分子间相互作用 . ESR结果表明 ,此水溶液体系的微极性随 SDS浓度增大而减小，并且 SDS与 PEO聚集体具有更加紧密的堆积结构使其结合处具有较大的微粘性， SDS与 PEO间的相互作用导致 PEO分子链伸展 . UV表明自旋探针分子可能靠近胶束的表面存在， 2， 4二硝基苯肼基团可能位于靠近 SDS的硫酸根基团，定向于 SDS胶束的表面，氮氧自由基基团短距离渗透到 SDS胶束的碳氢核 .

A novel colloid probe preparation method based on chemical etching technique

Several fundamental problems in hydrophobic force measurements using atomic force microscope (AFM) are dis-cussed in this paper. A novel method for colloid probe preparation based on chemical etching technology is proposed, which is specially fit for the unique demands of hydrophobic force measurements by AFM. The features of three different approaches for determining spring constants of rectangular cantilevers, including geometric dimension, Cleveland and Sader methods are com-pared. The influences of the sizes of the colloids on the measurements of the hydrophobic force curves are investigated. Our experimental results showed that by selecting colloid probe with proper spring constant and tip size, the hydrophobic force and the complete hydrophobic interaction force curve can be measured by using AFM.
