摘要
实验首次以柠檬酸为掺杂剂,以过硫酸铵为氧化剂通过化学氧化法合成了间氨基苯硼酸聚合物纳米材料,提出了相应聚合反应机理,并分析了柠檬酸与间氨基苯硼酸摩尔比对聚合产物形貌的影响。结果表明:通过该方法可以成功合成聚合间氨基苯硼酸纳米材料,柠檬酸与间氨基苯硼酸的摩尔比对产物形貌有重要影响,摩尔比为1∶1时,可以制备交织的弯曲纳米纤维。红外、XRD和热分析的结果表明:聚间氨基苯硼酸纳米纤维具有活性硼酸基团及聚苯胺类似的链结构,主要呈非晶形结构。
In this paper,a novel poly-3-aminophenylboronic acid nano-materials was synthesized with chemical oxidation method by using citric acid as doping agent and ammonium persulfate as oxidant,the corresponding polymerization mechanism has been presented and the effect of the molar ratio of citric acid and the monomer on the morphology of the polymer product has been studied,and the results show that poly-3-aminophenylboronic acid nano-materials can be successfully synthesized with this method,and the molar ratio of citric acid and the monomer has played an important role in the morphology of resultant product,when the molar ratio was adjusted at 1∶1,and a curved nanofiber can be prepared with this approach.The results of IR,XRD and thermal analysis show that：the poly-3-aminophenylboronic acid nanofiber has a similar chain structure with polyaniline and free boric acid group;the obtained nanofiber product mainly exists as amorphous structure.
