One of the beneficial effects of the present invention is that the composite solid capacitor provided by the present invention and the manufacturing method thereof can reduce the short circuit through the technical solution of “a plurality of soluble nanoparticles adsorbed on the
更進一步來說,本發明的其中一技術手段即是同時使用酸性鹽類以及多胺衍生物,例如:雙胺類,來作為輔助材料,使得原先受限於材料特性而無法均勻設置在電容器素子31的至少五個表面的可溶性奈米微粒可以通過輔助材料的作用而均勻分佈在電容器素子的不同表面上。 Furthermore, one of the technical means of the present invention is to use both acid salts and polyamine derivatives, such as diamines, as auxiliary materials, which was originally limited by the material properties and could not be evenly arranged in the capacitor element. The soluble nanoparticles of at least five surfaces of 31 can be uniformly distributed on different surfaces of the capacitor element by the action of auxiliary materials.
詳細而言,本發明是先針對酸性鹽類以及雙胺類分別選擇適當的溶劑以及配比,進而配置成鹽溶液以及胺溶液,並在設置或是塗佈可溶性奈米微粒之前先將酸性鹽類以及雙胺類都設置在電容器素子的五個表面上(例如四個側表面以及底面)。如此一來,通過可溶性奈米微粒與酸性鹽類以及雙胺類之間的交互作用,可以促使可溶性奈米微粒被均勻設置在電容器素子的五個表面上。如此一來,可以大幅改善可溶性奈米微粒的效果,進而降低電容器在運作時發生短路的機率。 In detail, the present invention first selects appropriate solvents and ratios for acid salts and diamines respectively, and then configures them as salt solutions and amine solutions, and then sets the acid salts before dissolving or coating soluble nanoparticles. Both types and diamines are provided on the five surfaces of the capacitor element (for example, the four side surfaces and the bottom surface). In this way, the interaction between the soluble nanoparticles and the acid salts and diamines can cause the soluble nanoparticles to be evenly arranged on the five surfaces of the capacitor element. In this way, the effect of soluble nanoparticles can be greatly improved, thereby reducing the probability of a short circuit during capacitor operation.
