It is found that the ablated surface morphologies for both the ti samples of different roughness have a similar change trend from roughening to smoothing with increasing the shot number , where the surface roughening is relatively weaker at lower ion current density 通过辐照不同原始粗糙度的纯金属ti发现,随着辐照次数的增加,烧蚀表面形貌均发生表面粗糙化向光滑化的转变。离子束流密度较低时,辐照表面的粗糙化程度较弱。
( 2 ) diamond - like carbon films could be fabricated by plasma enhanced chemical vapor deposition method too , the surface morphology of the films was good , but the films had very big internal stress , which could be decreased by adding proper nitrogen gas in work chamber ( 2 )用等离子体增强化学气象沉积技术也能制备类金刚石膜。优点是用这种方法制备的薄膜表面形貌得到了一定的改善,但内应力较大,通过加入适量的氮气可以改善一些。
Zero - expansion models satisfy the request of space structures for they can possess high dimensional stability in temperature - change fields . the surface morphology , electrical conductivity and spectral reflectivity of al / kapton films before and after space environment simulated tests were 对于al / kapton薄膜试验分别采用原子力显微镜、四探针电阻测量仪、紫外可见分光光度计测试其空间环境试验后的表面形貌、面电导率、光学反射率。
For the membranes modified by fe2 + / ooh initiation , the grafted hydrophilic polymers on the membranes surface has a more evenly distribution and a smoother surface morphology than that of the membranes modified by uv initiation . chondrocyte culturing was performed to evaluate the cytocompatibility of the control and the modified plla membranes 与紫外光引发接枝聚合所得到的plla改性膜相比,由fe ~ ( 2 + )辅助引发接枝聚合所得到的plla改性膜表面的亲水性聚合物的分布更为均匀,表面粗糙度较低。
The mechanical modifying equipment was used to prepare compounded micro - spheres from pmma particles and ps particles with metal particles and tio2 nano - particles . the sem was used to observe the images of particles and x - ray photoelectron spectroscopy ( xps ) is used to obtain surface spectrum . herein the tio2 nano - particles can be dispersed on larger polymer particles and their surface morphology is different by using different polymer particles 使用扫描电镜和光电子能谱对制得的复合微粒子进行表征,发现该方法可以使纳米tio _ 2粒子呈很好的分散状态复合在聚合物微球及金属粒子上,而且随着聚合物微球原料的不同,纳米tio _ 2粒子能在高聚物的表面的复合状态也不同。
The surface morphology of these films was characterized by sem technology . the results show that tcnq film is highly sensitive to nh3 . the pmma film doped by snpc is also highly sensitive to no2 with fast response speed , but the recovery time gets longer with the increase of gas concentration 实验探讨了不同转速对敏感性的影响,然后分别测试了各种膜的气体敏感性,结果表明,纯tcnq旋涂薄膜对氨气具有相当高的敏感度,但是响应和恢复时间较慢且随气体浓度增加而变长;掺入酞菁锡的pmma旋涂薄膜对氧化氮气体具有良好的响应时间和敏感性,但是恢复时间较慢。
Two coating approaches were adopted , one was to do next coating after 550 ? heat - treatment ( called a coating technique ) ; the other was to do next coating after 100 ? drying , the films coated by several times were heated at 550 ?
