MMA 的折射率和粘度用作仪器内置软件包的输入参数,用于尺寸分布反卷积。将样品干燥并与 KBr 粉末混合用于 FTIR 测量(PerkinElmer,Spectrum One System A,范围:7800-350 cm-1,分辨率:0.5-64 cm-1,透射模式)。将样品倒入光学深度为 1 cm 的石英池中,并通过紫外可见光谱(U-2810,Hitachi,190-1100 nm)进行测量。
FTIR spectrum was used to identify the above said films. C-V and I-V behavior of the MISM structures with Aluminum/PMMA/p-Si/Aluminum have been studied. The C-V behavior was studied for various frequencies (f) from 20 kHz to 1 MHz and for a bias voltage range of -20 V to +20 ...
采用傅里叶转换红外分析 ( FTIR), 扫描电子显微镜 (SEM) , 透射电子显微镜 (TEM) , 热重分析仪 (TG),X 射线衍射(XRD)和 X 射线光电子能谱(XPS)对 CeO2 空心球的形貌与结构组成进行表征.实验表明,CeO2 空心 球由立方萤石结构的颗粒组成,粒径约为 0.9 μm,壳层厚度约 40 nm.将 CeO2 空心微球作为...
The obtained measured ATR-FTIR spectrum of the PMMA pristine sample is in good agreement with the results of other experimental s tudies25–27,30,33,35,40. As can be seen from the figure, the ATR-FTIR spectra of the PMMA sample after argon plasma treatment does not reveal any ...
ATR FTIR spectra of PMMA polymer before and after plasma treatment measured in a wavenumber interval of 4000–400 cm−1. Argon flow rate 20 NL/min. Microwave power 460 W. Full size image The obtained measured ATR-FTIR spectrum of the PMMA pristine sample is in good agreement with the res...
Figure 7. Energy spectrum analysis of EDS under normal temperature environment and 30% alcohol treatment 图7. 常温环境,30%酒精处理下EDS能谱分析 王天鹏等 4. 退火去应力 PMMA材料在生产过程中不可避免的产生应力,在酒精溶剂或老化试验等进一步作用下,材料内部的微裂纹扩展成肉眼可见的裂纹。因此,降低PMMA材料...
PMMASiO2 纳米杂化材料的制备及作为润滑油添加剂的摩擦学性能
In addition, 19F MAS NMR spectrum can be investigated in detail owing to the large chemical shift range (4200 p.p.m.) of the 19F nuclei.12–14 Holstein et al.15,16 have investigated the polymorphism in PVDF using 1H-decoupled solid- state 19F MAS NMR. One PVDF sample, prepared through...
