Abstract

This study aimed to synthesize and conduct a preliminary characterization of particles produced through the emulsion and suspension polymerization of methyl methacrylate (MMA) in the presence of copper nanowires (CuNWs). These polymerization techniques offer insights into green polymerization methods. The resulting polymeric particles from both emulsion and suspension processes were analyzed using scanning electron microscopy (SEM), dynamic light scattering (DLS), transmission electron microscopy (TEM), and gel permeation chromatography (GPC). The particles synthesized via emulsion polymerization measured approximately 605 nm in size, and the emulsion exhibited stability, while the particles resulting from the suspension polymerization process were around 956 nm. GPC analysis indicated that polymerization in a heterogeneous medium maintained a controlled nature in the presence of CuNWs, as evidenced by the polydispersity index and the chain-extension reaction. The structure of PMMA was examined using FTIR and ¹H-NMR analyses, which validated the proposed structure.

在铜纳米线存在下的绿色聚合：乳液聚合和悬浮聚合

本研究旨在合成甲基丙烯酸甲酯（MMA）在铜纳米线（CuNWs）存在下的乳液和悬浮聚合所产生的颗粒，并对其进行初步表征。这些聚合技术提供了绿色聚合方法的见解。通过扫描电子显微镜（SEM）、动态光散射（DLS）、透射电子显微镜（TEM）和凝胶渗透色谱（GPC）分析了乳液和悬浮过程产生的聚合物颗粒。通过乳液聚合合成的颗粒尺寸约为605 nm，乳液具有稳定性，而通过悬浮聚合合成的颗粒尺寸约为956 nm。GPC分析表明，在非均相介质中，cunw存在时，聚合保持可控性质，多分散指数和链延伸反应证明了这一点。利用FTIR和1H-NMR对PMMA的结构进行了分析，验证了所提出的结构。

期刊介绍： "Polymer Bulletin" is a comprehensive academic journal on polymer science founded in 1988. It was founded under the initiative of the late Mr. Wang Baoren, a famous Chinese chemist and educator. This journal is co-sponsored by the Chinese Chemical Society, the Institute of Chemistry, and the Chinese Academy of Sciences and is supervised by the China Association for Science and Technology. It is a core journal and is publicly distributed at home and abroad. "Polymer Bulletin" is a monthly magazine with multiple columns, including a project application guide, outlook, review, research papers, highlight reviews, polymer education and teaching, information sharing, interviews, polymer science popularization, etc. The journal is included in the CSCD Chinese Science Citation Database. It serves as the source journal for Chinese scientific and technological paper statistics and the source journal of Peking University's "Overview of Chinese Core Journals."
