PDMS,即聚二甲基硅氧烷,是一种通用的电介质,最初是由美国Boehringer Mannheim GmbH开发的,用于制造汽车喷油器、汽车空调和汽车发动机系统。它是一种乳白色的乳液,能通过轻微的电场作用而被激活,从而形成一层薄的介质膜,具有良好的绝缘性、耐候性和抗腐蚀性。 PDMS的主要性质是其高折射率和高可见光透射率,即它能够...
1.2.3 接触角测量 使用OCA-25型光学接触角仪(德国DataPhysical Instruments GmbH),在5个不同位置使用体积为3 μL的液滴,采用滴液法测量水和油的表观接触角(CA),最终数据取这些测量数据的平均值。 1.3 PVDF/PDMS复合纤维膜的制备 将PVDF(4.5 ...
(3) 利用PDMS模具进行聚合物材料的热压 模压是在德国JENOPTIK Microtechnik GmbH公司制造的HEX01/T-A型高精度 热压机上进行。如图1中6所示。模压选择的聚合物材料主要为聚甲基丙烯酸甲 酯(PMMA)(购自南通三菱丽阳公司为2mm厚的片材。经差分扫描量热仪测定, 其玻璃化转变温度Tg为103'C。实验时,根据需要将PMMA片材...
在制备PDMS芯片过程中,为了实现高深宽比的结构,通常采用的PDMS芯片模具是硅模具,硅模具是通过硅的干法刻蚀技术直接在硅表面加工出高深宽比的结构,在这一领域的领军者之一,德国斯图加特的Robert Bosch GmbH,提出了一项专利的DRIE方法,通过在高频电感耦合等离子体反应离子蚀刻(ICP-RIE)系统中交替执行蚀刻和沉积步骤,实现...
The degradation temperature of the fabricated PDMS device was measured using thermogravimetric analysis (TGA) (NETZSCH-Geratebau GmbH, Germany). Each sample, weighing 10 mg, was heated in an Al2O3 85µL crucible at a rate of 20 mL/min from 25 °C to 800 °C with 20 mL/min purified ...
出版社: Wiley‐VCH Verlag GmbH 摘要: Polydimethylsiloxanes (PDMS) are used in many industrial products and processes and in a variety of consumer applications, such as coatings, polishes, detergents, personal care products, foods, and medicines. Described in this paper are the results of a ...
The wetting behavior of the PDMS substrate was investigated by contact angle measurement. The sessile drop technique using an OCA H200 instrument (DataPhysics Instruments GmbH) was performed at room temperature. A 2 μL drop of deionized water was dispensed on top of the PDMS surface. The acqu...
