Enhancing multi-micro/nanolayer polymers: synthesis, characterization, and impact of modified clay in ABS/PA6 blends
This study focuses on utilizing montmorillonite (MMT) to induce a multi-micro/nanolayer morphology in PA6/ABS blend polymers by mitigating phase retraction and coalescence. Both untreated and modified MMT were incorporated at weight contents ranging from 1 to 5 wt% to manipulate morphology through selective localization at the interface. The nanocomposites' morphology was analyzed, and the cooperative effects were correlated with their structural, thermal, rheological, and mechanical characteristics. Structural analysis revealed that intercalation resulted in the appearance of novel bands, particularly in CTAB-modified MMT, which adopted a tilted monolayer arrangement. SEM results demonstrated excellent distribution and dispersion of exfoliated modified MMT, effectively suppressing coalescence and promoting a finer multilayer morphology. Compared to nanocomposites based on unmodified MMT, the ones based on CTAB-modified MMT exhibited superior thermal stability. Furthermore, the stiffness of the blend matrix increased with clay content, and the nanocomposites stabilized with modified MMT showed enhanced strain-to-failure properties.
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."
