| 1 | The Sandfish's Skin:Morphology,Chemistry and Reconstruction显示文摘The sandfish is a lizard having the remarkable ability to move in desert sand in a swimming-like fashion. The most out-standing adaptations to this mode of life are the low friction behaviour and the extensive abrasion resistance of the sandfish skin against sand, outperforming even steel. We investigated the topography, the composition and the mechanical properties of sandfish scales. These consist of glycosylated keratins with high amount of sulphur but no hard inorganic material, such as silicates or lime. Remarkably, atomic force microscopy shows an almost complete absence of attractive forces between the scale surface and a silicon tip, suggesting that this is responsible for the unusual tribological properties. The unusual glycosylation of the keratins was found to be absolutely necessary for the described phenomenon. The scales were dissolved and reconstituted on a polymer surface resulting in properties similar to the original scale. Thus, we provide a pathway towards exploitation of the reconstituted scale material for future engineering applications. | Werner Baumgartner Friederike Saxe Agnes Weth David Hajas Darwin Sigumonrong Jens Emmerlich Martin Singheiser Wolfgang Bhme Jochen M.

| 2 | 烯烃自复分解反应对氢化丁腈橡胶相对分子质量的调控显示文摘利用凝胶渗透色谱技术研究了双键含量、催化剂用量及溶液浓度对氢化丁腈橡胶(HNBR)烯烃自复分解反应的影响。结果表明,双键含量高的HNBR更容易进行复分解反应;HNBR溶液质量分数为9%时,催化剂用量高于0.2phr才能使双键摩尔分数为20%的HNBR发生有效的复分解反应。适当提高HNBR的溶液浓度,也可提高HNBR的复分解反应效率。复分解降解后HNBR的门尼黏度降为原来的一半时,硫化胶的物理力学性能保持良好,拉伸强度、100%定伸应力、撕裂强度分别为改性前的70%、75%和94%。 | 潘庆燕 庄涛 赵菲 Obrecht Werner David Sarah | 2013 | 高分子材料科学与工程2013,29,12: | 3 |
| 3 | 氢化丁腈橡胶的烯烃复分解反应显示文摘研究了丁腈橡胶经选择性催化加氢后得到的氢化丁腈橡胶(HNBR)在钌基催化剂Zhan 1 B作用下以及有无外加低分子烯烃条件下的烯烃复分解反应,并用尺寸排阻色谱-多角度激光光散射-黏度检测联用仪对HNBR的2种烯烃复分解反应产物的结构进行了表征。结果表明,钌基催化剂Zhan 1 B可以有效地催化HNBR的烯烃复分解反应,降低其相对分子质量;HNBR的烯烃自复分解反应(无外加烯烃)比交叉复分解反应(有外加烯烃)的效率低;相对分子质量相同时,自复分解反应产物的均方旋转半径及特性黏数值均低于相应的交叉复分解反应产物,由此推断HNBR的烯烃自复分解反应产物主要为环状结构,而交叉复分解反应产物主要为线型结构。 | 潘庆燕 庄涛 赵菲 Werner Obrecht Sarah David | 2014 | 合成橡胶工业2014,37,5: | 2 |
