現今的潤滑油幾乎都是以礦物油為基礎的礦物性潤滑劑，然而石油儲存量有限，石化產物也會對環境有汙染，國際上統計大約有50%~60%使用過的潤滑油，最終流入環境造成汙染。近年來環保意識抬頭，人類也越來越注重個人的健康，因此所使用的產品及物品都希望是對人體無毒與天然，對環境傷害較小甚至是無害的，以致生質咖啡潤滑油之需求日益殷切。本論文的研究目標是以甘油和咖啡渣油混合，產生出有環境友善性的生質咖啡潤滑油。
由線接觸磨潤實驗驗證，本文已製造出優於一般礦物性潤滑油之生質咖啡潤滑油。同時此潤滑油之水含量越小，其磨潤性能越佳，同時發現混合適當界面活性劑、咖啡渣油與甘油可以改變生質潤滑油黏度，提高黏度指數與磨潤性能；又添加0.1 wt%~0.3 wt%生質奈米顆粒氧化銅可以有效提升本生質潤滑油的抗磨耗性能，甚至可以比礦物油更好；就初步實驗得知添加0.2 wt%界面活性劑的生質咖啡潤滑油劑有相當好的磨潤性能，我們由同比例的生質咖啡潤滑油再添加適量的生質奈米顆粒氧化銅磨潤效果都比礦物油好。

Modern lubricating oil is usually made based on mineral oil, however, the reserve capacity of petroleum is limited and petrochemical product will also cause the damage to the environment. According to international statistics, about 50% to 60% of used lubricating oil will eventually cause the pollution. Nowadays, with the growing level of environmental awareness, people started to place a high value on personal health, they wish to purchase natural and none toxic products, which can cause less damage or do no harm to the environment, therefore, the needs for coffee dregs biolubricant have increased dramatically. The purpose of the study is to produce eco-friendly coffee dregs biolubricant by mixing Glycerol and coffee dregs.
Proved by the tribological experiment of one line contact, the researchers have produced coffee dregs biolubricant which is superior to the normal lubricating oil. The less the water contains the better the tribological performance will be. Meanwhile, the researchers discovered that mixing the appropriate amount of surfactant, coffee dregs oil and Glycerol will increase the viscosity and the abrasion resistance of biolubricants. Adding 0.1 wt% to 0.3 wt% of CuO nanoparticles can promote the abrasion resistance effectively, even better than the mineral oil. In the preliminary test, coffee dregs biolubricant had an excellent tribological performance by adding 0.2 wt% of surfactant. The tribological performance was also better than the mineral oil when adding the right amount of CuO nanoparticles to the same
