摘要

探討奈米粒添加於潤滑油中的分散及表面改質，為了使奈米粉體能均勻的分散於潤滑油中，並獲得相對最小的粒徑及分散性良好之奈米粉體，進行物理方法及化學方法分散，將氧化鋅、銅、鋁及二氧化鈦奈米粉體分別使用界面活性劑油酸(Oleic Acid)及壬基酚聚乙氧基醇(NP-9)表面改質。
應用田口法標準直交表分配實驗參數，以最少次數實驗取得之數據進行回應分析，並預測奈米粉體之最小粒徑及獲得最佳參數組合。於最佳參數組合實驗中分別得到氧化鋅110 nm、銅105 nm、鋁65 nm及二氧化鈦94 nm之相對最小的粒徑，添加於潤滑油中進行沉澱測試，鋁相較於氧化鋅、銅及二氧化鈦可獲得較佳的穩定性。

In this study, we had discussed dispersion and surface modification of nanoparticles applying in lubrication oil. In order to disperse nanoparticles in lubricant oil uniformly and get the smallest diameter and well-dispersed of nanoparticles, we adopt some physical and chemical dispersion approaches. They contain oleic acid and nonylphenol polyethylene glycol ether to do surface modification with zinc oxide, copper, aluminum and titanium dioxide.
We applied orthogonal array for arranging parameters of experiment through taguchi method. Therefore, we got minimum times of experiments for analyzing the response data and predicted the smallest diameter and optimized parameters of nanoparticles. Through optimization of our parameters, we got the minimum diameters for zinc oxide, copper, aluminum and titanium dioxide which are 110 nm, 105 nm, 65 nm and 94 nm, respectively. In deposition test, aluminum had better stability compared with zinc oxide, copper and titanium dioxide.
