由本研究係以三軸滾輪機將環氧樹脂(Epoxy)當作基材，以氧化鋁粉(Al2O3)為主填充材，多壁奈米碳管(MWCNTs)為副填充材，在固定主要填充材與基材的比例下，添加1-5 wt.%之MWCNTs利用機械剪切力混合均勻，在140 oC下固化3小時，製成MWCNTs/Al2O3/Epoxy複合材料。後續利用SEM、Raman、電性量測、熱傳導量測、比熱量測、抗彎測試、溫升測試來分析材料性質。實驗結果顯示，相較於Epoxy，MWCNTs/Al2O3/Epoxy複合材在60 oC和 80 oC的熱傳導係數增加了300 % (1-5 wt.% CNTs)，比熱下降了20 % (3-5 wt.% CNTs)。而MWCNTs/Al2O3/Epoxy (50×50×5 mm)之複合材通12/24W電溫升到60 oC只需2分鐘/1分鐘，到80 oC只需3分半/1分半的時間。本研究製作出之MWCNTs/Al2O3/Epoxy複合材通低功率電即能快速且均勻自加熱，未來期許其能夠應用在電地暖及浴室除濕加熱磁磚系統材料上。

In this study, composites are made by epoxy as matrix to blend with the main fillers, Al2O3, as well as with the secondary fillers, mutli-walled carbon nanotubes (MWCNTs), at different ratios. Firstly, epoxy, CNTs and Al2O3 powders are evenly mixed by three-ball milling system to form adhesives. After degassing, the adhesives are cured at 140 oC for 3 h and pristine MWCNTs/Al2O3/epoxy composites are subsequently characterized by SEM and Raman. The glass transition temperature (Tg), mechanical, thermal and electrical properties are also measured, along with resistive heating experiments. The results show that comparing with pure epoxy, the specific heat of MWCNTs/Al2O3/Epoxy composite at 60 oC and 80 oC decrease 20 % (3-5 wt.% CNTs) and the thermal conductivity increase at least 300 % (1-5 wt.% CNTs) respectively. Input of low power (12-24 W) into composites (50×50×5 mm) produces heat and surface temperature reaches 60oC in 60-120 s and 80oC in 100-210 s respectively. Electrical heating of MWCNTs/Al2O3/Epoxy composites is low cost and is highly safety, capable of replacing existing electric floor heating systems.
