摘要

要优化生物材料表面的性能,就必须进行等离子处理。它能增强和调节生物材料表面的性能,与人体形成有效的界面。等离子处理能够改变表面的化学成分和物理结构,同时使其性能不受影响。等离子体具有改变材料表面、消除污染物、进行癌症治疗研究和促进伤口愈合的能力。有关研究课题涉及等离子科学技术与生物学和医学的结合。使用氦等离子喷射源,以 18 千伏的电压和 10 瓦的平均功率对聚合物箔进行 60 秒钟的处理。这项调查涉及在大气压力下对聚酰胺 6 和聚对苯二甲酸乙二醇酯薄片应用氦等离子体。调查包括监测和评估等离子源和聚合物材料,以及分析等离子治疗的影响。计算放电的平均功率有助于评估等离子源的经济效益。在大气压力下的氦气中进行放电对技术有好处,它可以增加聚合物材料的表面自由能。在生物医学领域,它可用于研究细胞毒性和细胞存活率,特别是在直接接触血液的情况下,可加速凝固。了解以预期方式影响等离子源的特定参数对于预期应用至关重要。

Helium Plasma Effects on Polymer Surfaces: from Plasma Parameters and Surface Properties towards Bioengineering Applications

Plasma treatment is necessary to optimize the performance of biomaterial surfaces. It enhances and regulates the performance of biomaterial surfaces, creating an effective interface with the human body. Plasma treatments have the ability to modify the chemical composition and physical structure of a surface while leaving its properties unaffected. They possess the ability to modify material surfaces, eliminate contaminants, conduct investigations on cancer therapy, and facilitate wound healing. The subject of study in question involves the integration of plasma science and technology with biology and medicine. Using a helium plasma jet source, applying up to 18 kV, with an average power of 10 W, polymer foils were treated for 60 s. Plasma treatment has the ability to alter the chemical composition and physical structure of a surface while maintaining its quality. This investigation involved the application of helium plasma at atmospheric pressure to polyamide 6 and polyethylene terephthalate sheets. The inquiry involves monitoring and assessing the plasma source and polymer materials, as well as analyzing the impacts of plasma therapy. Calculating the mean power of the discharge aids in assessing the economic efficacy of the plasma source. Electric discharge in helium at atmospheric pressure has beneficial effects in technology, where it increases the surface free energy of polymer materials. In biomedicine, it is used to investigate cytotoxicity and cell survival, particularly in direct blood exposure situations that can expedite coagulation. Comprehending the specific parameters that influence the plasma source in the desired manner for the intended application is of utmost importance.

期刊介绍: Chinese Journal of Polymer Science (CJPS) is a monthly journal published in English and sponsored by the Chinese Chemical Society and the Institute of Chemistry, Chinese Academy of Sciences. CJPS is edited by a distinguished Editorial Board headed by Professor Qi-Feng Zhou and supported by an International Advisory Board in which many famous active polymer scientists all over the world are included. The journal was first published in 1983 under the title Polymer Communications and has the current name since 1985. CJPS is a peer-reviewed journal dedicated to the timely publication of original research ideas and results in the field of polymer science. The issues may carry regular papers, rapid communications and notes as well as feature articles. As a leading polymer journal in China published in English, CJPS reflects the new achievements obtained in various laboratories of China, CJPS also includes papers submitted by scientists of different countries and regions outside of China, reflecting the international nature of the journal.
