Layer - by - layer方法的制備工藝條件很多，我們在以往實驗和理論分析的基礎上，介紹了對光敏性影響最為重要的工藝條件: 1 、循環次數的影響，實驗表明隨著循環次數地增加，光敏性變差; 2 、 h稀釋比的影響，隨著h稀釋比的不斷增加， h對生長表面的轟擊不斷增強，這些轟擊能優先消除高能缺陷結構而留下穩定的結構，從而使生長層結構緻密，減少缺陷態密度，提高薄膜的光敏性。On the basis of study on structure and mass transfer, ideal model of membrane structure was built up, in which skin layer should be as thin as possible ensure resisting water to pass though membrane ; finger pore should be as long as possible in the membrane ; proper pore size ; loose sponge tissue
首先對利用相轉化法制備的微孔膜形態結構進行研究，確定傳導阻力較小的理想結構模型，緻密層在能阻止微孔被浸潤的情況下盡可能薄；指狀孔在膜厚方向所佔比例盡可能大；孔徑大小適宜；海綿狀組織結構疏鬆。The mpgcfs observed by sem have such characteristics as the concentration of the deposited metal varied gradiently across the section of the film. one side is deposited phase, which is mainly composed of predominant metal and minal polymer ; and the other is undeposited phase, which is polymer matrix and hardly contains m etal ; and between the two side is the transition phase, where the polymer and metal interpenetrated
結果通過掃描電鏡發現，合成的mpgcf具有以下的特徵：金屬相在膜的厚度方向上呈梯度分佈，膜的一側為緻密的金屬，另一側為不含金屬的聚合物基體，兩側的中間為聚合物和金屬互相貫穿的過渡層。Brass wires are winded between two metallic electrodes located in a vacuum chamber, where 2 m thickness films are deposited onto the substrate glass after explosive wires discharging

電鏡下，鏈球菌感染后腎小球腎炎的電子緻密的免疫沉積物主要位於臟層上皮下，圖示基底膜右側一個大的臟層上皮下駝峰狀沉積物。As the pre - evaporation time increases, the holes on the membrane surface becomes smaller and less, dense layer is becoming more evident with large and deep holes in supporting layer ; and porosity increases as well - as average hole diameter decreases
隨著預蒸發時間的延長，膜表面的孔變小變少，膜的緻密層越來越明顯，支撐層有大而深的孔結構出現。隨著預蒸發時間的延長，膜的孔隙率上升，平均孔徑下降。It can be concluded that the performance differences between the plate membrane and the hollow fiber membrane can be attribute to difference of the stresses in the membranes when they were under pressure and the difference of the strain caused in the membrane, besides the possible reason that the surface curvature difference between a plate substrate and a hollow fiber one may cause structure difference in the dense functional layer when coating. the stresses in a hollow fiber composite membrane under an outside pressure are quite different from that in a plate one in that they exert on the hollow fiber in both the radial and circular directions, and the compress strain of the hollow fiber is thus much more complex, which may cause the top layer crinkle and a decreased salt rejection
分析認為造成平板復合膜（ ）和中空纖維復合膜（ ）性能差異的主要原因，除了平板基膜與中空纖維基膜因表面曲率不同可能引起在塗覆時形成的緻密功能層結構上的差異之外，由於中空纖維膜受外壓時，膜內部承受的應力形式與平板膜不同，會同時在徑向（膜厚度方向）和環向（膜面內方向）兩個方向產生壓應力，因此，所發生的形變也較為復雜，可能造成表面復合層的起皺或脫落，引起脫鹽率下降。The stainless steel and carbon steel can be excellently bonded under lower pressure by using silver intermediate sandwich materials and the oxide film on stainless steel can be destroyed effectively by argon gas shielding in the heating process
