Development of Plasma Processing Technology of Bio-Polymer Materials at Low-temperature

在本次研究中，我们的目标是开发和创造新的科学研究领域和创新技术，将新的生物医学研究领域与等离子体科学相结合。我们利用低气压微波等离子体或大气压介质阻挡放电等热非平衡等离子体，通过等离子体与聚合物表面的物理和化学作用，开展了生物聚合物的低温表面改性研究。在3年的时间里，我们进行了以下几个方面的研究：(1)等离子体修饰在聚合物表面引入官能团，(2)等离子体修饰在生物相容性材料上添加氨基，(3)等离子体与微生物的相互作用及微生物失活机理的阐明，(4)等离子体处理对生物材料生物功能的控制。

In the present research, we aim at developing and creating the new scientific research fields and innovative technology combined the new bio-medical research fields with the plasma science. We have carried out the researches of low-temperature surface modification of biopolymer through physical and chemical interaction between plasma and polymer surface using thermal non-equilibrium plasmas, such as low-pressure microwave plasma or atmospheric dielectric barrier discharge. During 3 years, we have studied the following subjects ; that is, (1) Functional group introduction onto the polymer surface by plasma modification, (2) Amino group addition onto the biocompatible materials by plasma modification, (3) Interaction between plasma and microorganisms and clarification of inactivation mechanism of microorganisms, and (4) Control of biological function of biomaterials by plasma processing.
