摘要

在功能聚丙烯（FPP）或热处理聚丙烯（HTFPP）基体中加入改性钛酸铜钙（MCCTO）或功能活性炭（FANC）颗粒，以提高 FPP 作为介电薄膜的性能。通过对制备的 FPPwxMCCTOy、FPPwxFANCz、FPPwxMCCTOyFANCz 和 HTFPPwxMCCTOy、HTFPPwxFANCy 和 HTFPPwxMCCTOyFANCz 薄膜进行测试和表征、研究发现，当 MCCTO 和 FANC 负载分别接近 8 和 6 wt% 时，FPPwxMCCTOy、FPPwxFANCz、HTFPPwxFANCz 和 HTFPPwxFANCz 薄膜的介电常数和放电能量密度均达到最大值。FPPwxMCCTO8FANCz 和 HTFPPwxMCCTO8FANCz 系列薄膜在 FANC 负载接近 6 wt% 时也获得了最大介电常数和放电能量密度。正确制备的 HTFPPw86MCCTO8FANC6 薄膜的放电能量密度为 3.2 J/cm3，是 FPP 的 3 倍多。当 MCCTO 和 FANC 负载分别为 ≦8 和 6 wt% 时，随着添加剂含量的增加，在 FPPwxMCCTOy（或 HTFPPwxMCCTOy）、FPPwxFANCz（或 HTFPPwxFANCz）和 FPPwxMCCTO8FANCz（或 HTFPPwxMCCTO8FANCz）系列薄膜截面上观察到更密集的 MCCTO 和 FANC 分布。在本文中，我们提出了在适当热处理或添加适当的 MCCTO 和/或 FANC 负载后，电容薄膜的介电常数、放电能量密度和耐热性明显改善的可能原因。

Preparation and characterization of nano‐filled polypropylene dielectric films

Modified copper calcium titanate (MCCTO) or functional activated carbon (FANC) particles were added to functional polypropylene (FPP) or heat‐treated polypropylene (HTFPP) matrix to improve the performance of FPP as dielectric films. By testing and characterizing the prepared FPPwxMCCTOy, FPPwxFANCz, FPPwxMCCTOyFANCz and HTFPPwxMCCTOy, HTFPPwxFANCy and HTFPPwxMCCTOyFANCz films, It is found that the dielectric constant and discharge energy density of each FPPwxMCCTOy, FPPwxFANCz, HTFPPwxFANCz and HTFPPwxFANCz films reach the maximum when the MCCTO and FANC loads are close to 8 and 6 wt% respectively. FPPwxMCCTO8FANCz and HTFPPwxMCCTO8FANCz series films also obtain the maximum dielectric constant and discharge energy density at FANC load approaching 6 wt%. The discharge energy density of HTFPPw86MCCTO8FANC6 film prepared properly is 3.2 J/cm3, which is more than 3 times higher than that of FPP. When MCCTO and FANC loads are ≦8 and 6 wt% respectively, with the increase of additive content, More dense distribution of MCCTO and FANC was observed in FPPwxMCCTOy(or HTFPPwxMCCTOy), FPPwxFANCz(or HTFPPwxFANCz) and FPPwxMCCTO8FANCz(or HTFPPwxMCCTO8FANCz) series film sections. In this paper, we propose possible explanations for the apparent improvement in dielectric constant, discharge energy density and heat resistance of capacitive films after appropriate heat treatment or addition of appropriate MCCTO and/or FANC loads.

期刊介绍： Polymers for Advanced Technologies is published in response to recent significant changes in the patterns of materials research and development. Worldwide attention has been focused on the critical importance of materials in the creation of new devices and systems. It is now recognized that materials are often the limiting factor in bringing a new technical concept to fruition and that polymers are often the materials of choice in these demanding applications. A significant portion of the polymer research ongoing in the world is directly or indirectly related to the solution of complex, interdisciplinary problems whose successful resolution is necessary for achievement of broad system objectives. Polymers for Advanced Technologies is focused to the interest of scientists and engineers from academia and industry who are participating in these new areas of polymer research and development. It is the intent of this journal to impact the polymer related advanced technologies to meet the challenge of the twenty-first century. Polymers for Advanced Technologies aims at encouraging innovation, invention, imagination and creativity by providing a broad interdisciplinary platform for the presentation of new research and development concepts, theories and results which reflect the changing image and pace of modern polymer science and technology. Polymers for Advanced Technologies aims at becoming the central organ of the new multi-disciplinary polymer oriented materials science of the highest scientific standards. It will publish original research papers on finished studies; communications limited to five typewritten pages plus three illustrations, containing experimental details; review articles of up to 40 pages; letters to the editor and book reviews. Review articles will normally be published by invitation. The Editor-in-Chief welcomes suggestions for reviews.
