  摘要：

  研究了基于两亲性聚苯乙烯和聚甲基丙烯酸酯的β-酰氧基酮，作为在功能性香水应用中通过逆向-1,4-加成控制达马康酮释放的潜在传递系统。以2,2'-偶氮二[2-甲基丙腈]（AIBN）为自由基源，通过有机溶液中的自由基聚合反应，得到由疏水性达马康酮释放单元和第二种亲水性单体组成的一系列无规共聚物（方案2）和3）。在酸性或碱性缓冲水溶液中，在表面活性剂存在下，对聚合物共轭物的首次评估表明，具有羧酸官能团的亲水性基团的聚甲基丙烯酸酯和聚苯乙烯对于目标应用特别感兴趣（表2）。因此，通过比较荧光探测，溶剂萃取，在pH为4、7和9的情况下，几天后从具有不同化学计量比的聚（甲基丙烯酸）和聚（乙烯基苯甲酸）共聚单体的聚合物中释放出δ-达马可康（1）。和粒度测量（表3和4）。在酸性介质中，发现聚合物是稳定的，几乎没有δ-damascone（1）已发布。在羧酸官能团去质子化的中性或碱性溶液中，浓度1随时间增加。在

  A bio-electrode composition contains (A) a composite of an ionic polymer material and particles. The component (A) contains the particles bonding to the polymer containing a repeating unit having a structure selected from the group consisting of salts of ammonium, lithium, sodium, potassium, and silver formed with any of fluorosulfonic acid, fluorosulfonimide, and N-carbonyl-fluorosulfonamide. Thus, the present invention provides: a bio-electrode composition capable of forming a living body contact layer for a bio-electrode which is excellent in electric conductivity and biocompatibility, light-weight, and manufacturable at low cost, and which prevents significant reduction in the electric conductivity even when wetted with water or dried; a bio-electrode including a living body contact layer formed of the bio-electrode composition; and a method for manufacturing the bio-electrode.
