A polyvinylidene fluoride (PVDF) film incorporating size-controlled, uniformly dispersed, directly patterned Bi2O3 nanoparticles was developed to achieve a high-k polymer nanocomposite capacitor. The photochemical metal-organic deposition (PMOD) method was employed to form uniformly dispersed and directly patterned nanoparticles on the substrate. Bi nanoparticles were produced by spin coating a Bismuth 2-ethylhexanoate solution on a Pt substrate with UV irradiation for 1, 4, 7, and 10 min. The average diameter of nanoparticles and the number of nanoparticles per unit area (μm2) were about 30, 70, and 120 nm and 30, 30, and 31 particles/μm2 for UV irradiation times of 4, 7, and 10 min, respectively. In addition, the capacitance of PVDF nanocomposite film could be controlled by the Bi2O3 nanoparticle size. The PVDF nanocomposite film containing Bi2O3 nanoparticles with 1, 4, 7, and 10 min UV irradiation were able to improve capacitance by about 1.4, 2.0, 2.7, and 3.4 times compared with an as-prepared PVDF film. By using a mask aligner, directly pattered Bi nanoparticles on the substrate, which had a 5 μm line width pattern, were successfully defined and demonstrated.

用于聚合物纳米复合电容器的可直接图案化的Bi2O3纳米颗粒

开发了一种聚偏二氟乙烯(PVDF)膜,该膜结合了尺寸受控,均匀分散,直接构图的Bi 2 O 3纳米颗粒,从而获得了高k聚合物纳米复合电容器。使用光化学金属有机沉积(PMOD)方法在基板上形成均匀分散并直接构图的纳米颗粒。Bi纳米粒子是通过将2-乙基己酸铋溶液在UV辐射下旋转涂覆在Pt基板上1、4、7和10分钟而制得的。纳米粒子的平均直径和每单位面积的纳米颗粒的数目(微米2)分别为约30,70,和120纳米和30,30,和31个颗粒/微米2UV照射时间分别为4、7和10分钟。另外,PVDF纳米复合膜的电容可以通过Bi 2 O 3纳米颗粒尺寸来控制。与制备的PVDF膜相比,包含Bi 2 O 3纳米粒子的PVDF纳米复合膜具有1、4、7和10分钟的紫外线照射,其电容量可提高约1.4、2.0、2.7和3.4倍。通过使用掩模对准器,成功地定义并证明了在基板上直接构图的Bi纳米粒子具有5μm的线宽图案。
