Abstract

A lignosulfonate (LS)-derived thermoplastic was synthesized using a simple and scalable grafting reaction with a polyethylene glycol derivative (phenylPEG). The grafted polymer, polyethylene glycol-grafted LS (LS-g-PEG), had improved thermo-moldability and mechanical properties in a bending test, compared with pure LS and an LS/phenylPEG (LS/PEG) blend. Small-angle X-ray scattering analyses showed that LS-g-PEG had a nano-scale (20–30 nm) homogeneous lamellar structure, whereas the LS/PEG blend was separated into an LS-rich phase and a crystalline phenylPEG lamellar phase. The nano-scale structure of LS-g-PEG provides macroscopic homogeneity, as confirmed by fracture surface observation and polarized microscopy analysis; its high homogeneity resulted in enhanced thermo-moldability and mechanical properties, compared with an LS/PEG blend.

简单和可扩展的合成木质素磺酸衍生热塑性塑料与改进的热学和机械性能

以聚乙二醇衍生物(phenylPEG)为原料，通过简单、可扩展的接枝反应合成了木质磺酸盐(LS)衍生的热塑性塑料。与纯LS和LS/苯基PEG (LS/PEG)共混物相比，接枝聚合物聚乙二醇接枝LS (LS-g-PEG)在弯曲试验中具有更好的热塑性和力学性能。小角度x射线散射分析表明，LS-g-PEG具有纳米级(20-30 nm)均匀的片层结构，而LS/PEG共混物则分为富LS相和结晶苯PEG片层相。断裂表面观察和偏光显微镜分析证实，LS-g-PEG的纳米级结构具有宏观均匀性;与LS/PEG共混物相比，其高均匀性增强了热成型性和机械性能。

期刊介绍： Composites Part B: Engineering is a journal that publishes impactful research of high quality on composite materials. This research is supported by fundamental mechanics and materials science and engineering approaches. The targeted research can cover a wide range of length scales, ranging from nano to micro and meso, and even to the full product and structure level. The journal specifically focuses on engineering applications that involve high performance composites. These applications can range from low volume and high cost to high volume and low cost composite development. The main goal of the journal is to provide a platform for the prompt publication of original and high quality research. The emphasis is on design, development, modeling, validation, and manufacturing of engineering details and concepts. The journal welcomes both basic research papers and proposals for review articles. Authors are encouraged to address challenges across various application areas. These areas include, but are not limited to, aerospace, automotive, and other surface transportation. The journal also covers energy-related applications, with a focus on renewable energy. Other application areas include infrastructure, off-shore and maritime projects, health care technology, and recreational products.
