Abstract
The development of composite materials with fewer interface problems always helps to obtaining good properties. Two types of insulating biopolymers (7% w/w) were incorporated into a conductive matrix (polyaniline) during polymerization. The synthesis method, inspired by the synthesis of polyaniline and the coating of chitosan for the development of flexible electrodes, produces thermosets that are more thermally stable than the matrix until 350 °C. While one (gum) reduces the electrical conductivity, the other (lignin) increases the basic value of the raw material (~ 0.72 S Cm–1) by a factor of 10. The physicochemical and morphological analyses show the formation of the polymer on the surface of the biopolymer with the appearance of new chemical bonds by interactions between hydroxyls of the biopolymer and the nitrogen of amine function from the polyaniline.
开发界面问题较少的复合材料总是有助于获得良好的性能。在聚合过程中将两种绝缘生物聚合物（7% w/w）加入到导电基质（聚苯胺）中。这种合成方法受到聚苯胺合成和壳聚糖涂层的启发，用于开发柔性电极，生产出的热固性材料在 350 °C 之前的热稳定性高于基体。其中一种（树胶）降低了导电性，而另一种（木质素）则将原材料的基本值（~ 0.72 S Cm-1）提高了 10 倍。物理化学和形态分析表明，生物聚合物表面形成了聚合物，生物聚合物的羟基与聚苯胺的胺功能氮相互作用，形成了新的化学键。
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."
