    • 摘要: 描述了一种结合光刻和热键合工艺制作压电喷墨腔室的工艺方法,并对喷墨腔室的键合质量进行研究.首先在Si基底上制作完全交联的SU-8开放腔室,然后在PDMS基底上采用邻近式紫外曝光得到带有锥形喷孔的喷孔板,最后将喷孔板与开放腔室热键合得到一体化的喷墨腔室.通过控制曝光量来得到不同交联程度的喷孔板,测量不同交联程度下喷墨腔室的键合强度;通过优化氧等离子体处理工艺参数,提高了喷墨腔室的键合强度;此外,优化了热键合温度和键合时间,获得最小的腔室变形量.

    • 摘要: 二维纳米阵列结构因其重要的光学性能被广泛应用于各类光电子器件.本文对自组装单层SiO2纳米球掩模刻蚀法制备GaAs纳米柱二维阵列结构的关键工艺技术进行了研究.采用旋涂法在GaAs表面制备自组装单层SiO2纳米球,重点研究了GaAs表面氧等离子体亲水处理工艺对纳米球排列特性的影响,获得最佳工艺条件为功率配比100 W+80 W、腔室压力4 Pa、氧气流量20 mL/min、处理时间1200 s,并最终得到排列紧密的大面积单层纳米球薄膜.以单层纳米球为掩模,采用感应耦合等离子体刻蚀技术在GaAs表面制备了纳米柱阵列并测试了其表面光反射谱.测试结果表明,GaAs纳米柱阵列在特定波段的反射率降低至5%,远低于表面无纳米结构的薄膜材料表面高达40%的光反射.分析表明纳米柱可以激发米氏散射共振效应,从而有效降低反射率并提升光吸收.

    • 摘要: 通过在放电回路中连接电容来控制放电电荷数目并得到稳定的氧等离子体.利用测量的电压电流波形和放电图像的变化分析了放电模式在不同应用电压下的转化过程.根据等离子体发射光谱计算了各种活性物种的发射光谱强度,模拟了等离子体气体温度、振动温度的变化过程.结果表明:随着应用电压的增加,等离子体放电模式在电压正半周明显地从流光放电转化为辉光放电最后转化为弧光放电,在电压负半周从电晕放电转化为弧光放电.在放电回路中加入电容可以限制单次放电的电荷数目,提高放电的稳定性.与放电模式的转化相对应,等离子体的气体温度先增加后不变.

    • 摘要: 使用微波等离子体技术(microwave plasma chemical vapor deposition,MPCVD)对膜厚100 μm的(100)和(111)晶面金刚石膜进行刻蚀处理,研究其抗氧等离子体的行为。结果表明:(100)晶面刻蚀首先发生在晶棱晶界处,而(111)晶面金刚石的刻蚀首先发生在晶面处;30 min刻蚀后,(100)面金刚石有明显晶面显现,(111)面金刚石膜晶面不明显;60 min刻蚀后,(100)和(111)晶面金刚石膜的择优取向消失;(100)晶面金刚石特征峰的半高宽值(full width at the half maximum,FWHM)由刻蚀前的8.51 cm–1上升至刻蚀后的12.48 cm–1,(111)晶面金刚石FWHM值由8.74 cm–1上升至148.49 cm–1;(100)晶面金刚石膜刻蚀速率在40 min时为0.35 μm/min,60 min时上升至1.34 μm/min;刻蚀前期,(100)晶面金刚石膜具有更好的抗氧等离子体刻蚀能力,刻蚀后期其抗刻蚀能力与(111)晶面金刚石膜相似。%The resistance abilities of (100) and (111)-faceted diamond films against oxygen plasma, 100 μm as film thickness, were investigated by the microwave power chemical vapor deposition (MPCVD) technique. The results indicate that the preferred etching points of the (100)-faceted diamond films are located at the grain boundaries and the preferred etching points of the (111)-faceted diamond films are located at the crystal surfaces. After 30 minutes etching, the (100)-faceted crystal can still be obviously shown while the (111)-faceted crystal is unobvious. After 60 minutes etching, the preferential orientations of (100)-faceted and(111)-faceted diamond films both are disappeared. The FWHM value of the (100)-faceted diamond films is increased from 8.51 cm–1 to 12.48 cm–1 and the FWHM value of the(111)-faceted diamond films is increased from 8.74 cm–1 to 148.49 cm–1 when the etching time is 60 minutes. The etching rate of the (100)-faceted diamond film is 0.35 μm/min when the etching time is 40 minutes and it is increased to 1.34 μm/min when the etching time is 60 minutes. At early stage, the (100)-faceted diamond film presented better resistance ability than the (111)-faceted diamond film against the oxygen plasma etching. But the resistance abilities to the plasma etching of the (100) and the (111)-faceted diamond films are similar when the etching time is 60 minutes.

    • 摘要: 采用一种新型的金刚石颗粒制备方法,利用微波辅助化学气相沉积技术,向反应室内通入氢气,以固态石墨片同时作为碳源和衬底沉积金刚石颗粒。利用该方法合成的金刚石颗粒具有微米级尺寸,可用作研磨剂、抛光剂、形核剂等。但是合成的金刚石颗粒中仍含有少量的非晶碳,且合成颗粒的尺寸均匀性有待提高。为解决以上问题,本文中在反应不同阶段(初期、中期及末期)通入氧气,形成氧等离子体;研究氧等离子体对合成的金刚石颗粒形貌、尺寸、质量、纯度的影响,以及随氧等离子体添加阶段不同而产生的不同变化情况。结果表明,经氧等离子体处理的金刚石颗粒形貌略有改变,表面光滑度更好,且金刚石颗粒尺寸的一致性有所提高;经过激光粒度测试发现,金刚石颗粒的尺寸主要集中在25~29μm。添加氧等离子体有助于消除金刚石中的非晶碳,提高金刚石纯度;且在反应初期添加氧等离子体可最大程度提高金刚石颗粒质量。

    • 摘要: 首先对聚对苯二甲酸乙二醇酯(PET)薄膜进行氧等离子体预处理,然后通过原位化学氧化聚合法使得吡咯单体在PET薄膜表面沉积聚合,制备了聚对苯二甲酸乙二醇酯/聚吡咯(PET-PPy)复合膜.通过原子力显微镜、X射线光电子能谱仪、ξ电位测试对经不同时长的氧等离子体预处理的PET薄膜进行表征;利用扫描电子显微镜、耐磨性实验和表面电阻测试对PET-PPy复合膜磨损前后的表面形貌和电阻进行分析与表征.结果表明,氧等离子体预处理显著增强了PET-PPy复合膜界面粘附性.氧等离子体预处理使PET薄膜表面粗糙度增大、电负性显著增强.特别地,当预处理时间为120 s时,薄膜表面电负性明显增强,此时PET-PPy复合膜磨损后的电阻值变化最小,表明PET薄膜与PPy功能层界面粘附强度得到明显增强.%Polyethylene terephthalate (PET) films were pretreated with oxygen plasma firstly.Then,polypyrrole (PPy) functional layers were polymerized on the surface of PET films to form PET-PPy composite films by in situ chemical oxidation polymerization method.Atomic force microscopy,X-ray photoelectron spectroscopy and zeta potential measurement were used to characterize PET films pretreated with oxygen plasma for different durations.The surface morphology and electrical resistance of PET-PPy composite films before and after abrasion were investigated by scanning electron microscopy,abrasion resistance and sheet resistance measurements.The results showed that the interfacial adhesion of PPy functional layer to PET film is significantly improved by oxygen plasma pretreatment.The increased surface roughness and the enhanced electronegativity are the leading factors for the improved adhesion strength.In addition,the optimal pretreatment duration is 120 s.

    • 摘要: 采用静电纺丝法制备了ZnO纳米纤维材料并使用氧等离子体对其进行表面处理.通过X射线衍射(XRD),扫描电子显微镜(SEM),BET比表面积测试以及X射线光电子能谱分析(XPS)等手段对样品的结构与形貌进行了表征分析.将氧等离子体处理前后的ZnO纳米纤维分别制成气体传感器,对浓度为1×10-6~100×10-6(体积分数)丙酮气体的敏感特性进行了测试分析.测试结果表明,氧等离子体处理后的ZnO纳米纤维响应值较未处理的ZnO纳米纤维有大幅度的提升,最佳工作温度也有所降低,且对甲醛、苯、甲苯、二甲苯等几种干扰气体表现出更好的选择性.从晶粒间势垒和耗尽层厚度等角度初步分析了氧等离子体处理改善ZnO气敏特性的机理.%ZnO nanofibers were synthesized by an electrospinning method and subsequently treated by oxygen plas-ma. The structure and morphology of the samples were characterized using X-ray diffraction( XRD) ,scanning elec-tron microscopy(SEM),Brunner-Emmet-Teller(BET)measurements and X-ray photoelectron spectroscopy(XPS). The sensitivity of the plasma treated and untreated ZnO nanofibers towards acetone from 1 × 10-6 to 100 × 10-6 ( volume fraction) was investigated. It was found that the gas sensing properties of ZnO nanofibers to acetone vapor obviously improved after it treated by oxygen plasma,such as decreasing the operating temperature and enhancing the response value. Meanwhile,the responses of the treated ZnO nanofibers sensor to formaldehyde,benzene,xylene and methylbenzene decrease,indicating an improved selectivityand anti-disturbance from interference to acetone va-por. The improvement mechanism of ZnO nanofibers treated by oxygen plasma is analyzed briefly by means of deple-tion layer thickness and potential barriers between grains.
