But for the strong activity of Nano-TiO2, the conglobation will happen easily, and it will greatly reduce the application effect in coating. And for the hydrophilicity , its hard to break up uniform in resins, so air gaps appear in the interface, then the high polymer in the interface willhappen degradation reaction or embrittlement reaction, and coatingsperformance will fall down.

但是由于纳米粒子表面极强的活性，使它们很容易团聚在一起从而形成带有若干弱连接界面的尺寸较大的团聚体，这大大降低甚至消除了纳米颗粒的实际应用效果，同时由于纳米粒子表面亲水疏油，在有机高分子树脂中难于均匀分散，界面上会出现空隙，当空气中的水分进入空隙中就会触发界面处高聚物的降解、脆化，导致涂层失效。

We make chloroacetylaion to N-terminal of Asp, and then convert this compound to GD dipeptide by aminolysis. Followed the lipase -catalyzed peptide synthesis of RGD in aqueous water-miscible organic cosolvent is studied. We set up a new efficient reaction method to synthesize RGD tripeptide. The problem that peptide containing polar amino acid can not be synthesized readily in organic solvent was solved. We offer a new experimental proof for PPL-catalyzed peptide synthesis and make a more general analysis for the effect of some factors in theory.

Further more researches indicate that it is just the bacteria adhereing that decrease surface free energy of pyrite and reduce the effect of catching pyrite by catching medicament. But the desulfurization is not the oxidation action of microbial or decreasing its hydrophile of pyrite.

而且发现正是由于T.f菌及其分泌物的吸附使黄铁矿的表面自由能减小，从而降低了捕收剂对黄铁矿的捕收效果，不是由于细菌氧化的作用或通过增加黄铁矿的亲水作用而脱除黄铁矿硫的。

The result indicated that, gathers in advance the emulsion water resistance and mechanics performance which in the body preparation method the one-stage process obtains is good, but two steps obtain the emulsion stability is good; The neutralizaing agent triethylamine amount used should enable to achieve neutral between x-y, to gathers in advance the body disperser and the emulsion stability only then is advantageous; The water affinity chain extendor DMPA content to the emulsion viscosity, stable and the emulsion cellophane water resistance has the remarkable influence, its amount used general control between x-y; Hard section isocyanogen diethylene glycol dinitrate primary control paint film degree of hardness, module, anti-avulsion, wear-resisting and so on performance, the soft section low-molecular polymer polyols primary control paint film elasticity, hydrolisis performance and so on bears the low temperature and bears

结果表明，预聚体制备方法中一步法得到的乳液的耐水性和力学性能较好，而两步法得到的乳液的稳定性好；中和剂三乙胺的用量应使中和度达到x-y之间，对预聚体的分散和乳液的稳定性才有利；亲水扩链剂DMPA的含量对乳液的粘度、稳定性及乳液胶膜的耐水性有着显著的影响，其用量一般控制在x-y之间；硬段异氰酸酯主要控制涂膜的硬度、模量、抗撕裂、耐磨等性能，软段低聚物多元醇主要控制涂膜的弹性、耐低温和耐水解等性能

同时，软硬单体比例、具有亲水功能的甲基丙烯酸MAA单体的用量、反应温度和引发剂的用量等对胶乳的粒径和应用后织物的性能都有不同程度的影响。

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5.
