One kind having the metal of antibiotic layer, includes a metal body and an antibacterial epithelium. The antibacterial epithelium is antibiotic layer,The antibacterial epithelium uniformly plates the outer surface of the what metal body,When friction generates static potential difference between the antibacterial epithelium and bacterium,The antibiotic leather film strips positive charge,And bacterium is negatively charged,And then the cell membrane for destroying bacterium makes the tissue fluid of bacterium outflow,Protein generates solidification phenomenon and bacterium is allowed to lose activity,The DNA biosynthesis block of bacterium is finally forced,And lose the ability of schizogamy and dead,Really reach the effect of antibacterial,And the characteristic of the antibacterial epithelium can't decay with the time,Can constantly have effects that sterilization.一種具有抗菌層之金屬物品，包含一個金屬本體，及一個抗菌皮膜。該抗菌皮膜為抗菌層，該抗菌皮膜均勻鍍於該金屬本體的外表面，該抗菌皮膜與細菌之間摩擦產生靜電電位差時，該抗菌皮膜帶正電荷，而細菌帶負電荷，進而破壞細菌的細胞膜使得細菌的組織液外流，蛋白質產生凝固現象而讓細菌失去活性，最終迫使細菌的DNA合成受阻，且喪失分裂繁殖的能力而死亡，確實達成抗菌的效果，且該抗菌皮膜的的特性並不會隨著時間衰減，能夠持續地具有殺菌的功效。
