Abstract

This study presents the one-step grafting of N-vinylcaprolactam (NVCL) and methacrylic acid (MAAc) onto polypropylene (PP) suture threads using gamma radiation. A 1:1 solution of the monomers was applied directly to the PP substrate and irradiated to induce graft copolymerization. The effects of monomer concentration and absorbed gamma-ray dose were evaluated, as they influenced the degree of grafting achieved. The thermal and mechanical properties of the grafted material, PP-g-(NVCL-co-MAAc), were analyzed to assess its potential functionality. The results suggest that the modified suture is a promising candidate for use in controlled drug-loading and release systems in biomedical and sanitary applications.

一步γ射线诱导聚（n-乙烯基己内酰胺）和聚（甲基丙烯酸）接枝到聚丙烯缝线上

本研究采用伽马射线将n -乙烯基己内酰胺（NVCL）和甲基丙烯酸（MAAc）一步接枝到聚丙烯（PP）缝线上。以1:1的单体溶液直接作用于PP底物上，辐照诱导接枝共聚。评价了单体浓度和吸收的γ射线剂量对接枝程度的影响。对接枝材料PP-g-(NVCL-co-MAAc)的热力学性能进行了分析，以评估其潜在的功能。结果表明，这种改良的缝线在生物医学和卫生领域的药物控制加载和释放系统中有很好的应用前景。

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
