| Abstract: | 本實驗利用16錠編帶機將聚乳酸（PLA）複絲製備成聚乳酸編織物，對其進行鹼處理達表面粗糙化，之後將聚乳酸編織物浸置於電鍍液（模擬體液）中，並固定於陰極電極上，施以固定電流和不同時間來加速氫氧基磷灰石（HA）的生成，其後再將電化學處理後之樣品分別浸泡於模擬體液中1天、3天、5天。最後利用掃描式電子顯微鏡觀察表面形態、X光繞射儀進行結晶繞射分析與傅立葉轉換紅外光譜儀進行光譜分析。由實驗結果得知在電化學處理30分鐘時即有氫氧基磷灰石之生成，又在電化學處理30分鐘後浸泡模擬體液１天時，得到類似文獻中單純浸泡模擬體液15天之HA型態。
In this study, the polylactic acid (PLA) fibers were braided by a 16-spindle braid machine, and increased PLA fibers surface rough of alkali treatment. After that, the PLA braiding soaked in simulated body fluid and fixed to the cathode electrode, and entered into stationary current and different times to speed up the hydroxyapatite (HA) deposition. After the sample of electrochemical treatment were immersed in simulated body fluid in 1day, 3days, and 5days. Using Scanning Electron Microscope (SEM) observed surface morphology, X-ray diffiaction (XDR) for crystal diffiaction analysis and Fourier transform in infrared spectrometer (FTIR) for spectrum analysis. Hydroxyapatite was generated by electrochemical treatrnent for 30 minutes In the electrochemical treatrnent for 30 minutes then immersed in simulated body fluid in 1 day, in the result of the HA type is similar to reference by immersed in simulated body fluid in 15days. |
