本研究使用的多孔性陶瓷板基材主成分為氧化鋁及二氧化矽，披覆的奈米塗料則是包含TiO2、SiO2及Al2O3的奈米顆粒。藉由不同的測試配方找出最佳塗佈條件，讓奈米塗層能直接塗附並經自然乾燥而緊密披覆於陶瓷基板上，達到抗菌除藻防污的功效。實驗結果顯示，使用的奈米塗層其厚度約為100nm，經過1000次細海綿的洗刷，依然保有約80~90nm左右的厚度。在抗菌測試方面，使用大腸桿菌作為試驗菌株經過18小時的培養，披覆奈米塗層的陶瓷板能夠有效的將菌數從4.93´109(cfu/mＬ)降低至1.94´105(cfu/mＬ)，抗菌率達到99.99%。而將此一具奈米鍍層的陶瓷板置於充滿綠藻的魚缸中，經過60小時後則可以有效的清除魚缸中的藻類，恢復魚缸中水質的澄清。此一技術可藉由將多孔性陶瓷板製造成各種成品配件而應用於水產養殖或是觀賞魚缸的抗菌及除藻。

Study of the porosity ceramics is basically made up of Al2O3 and SiO2. Nano -covered material contains nano TiO2, SiO2 and Al2O3 particles. By using a different test prescription to figure out the best spreading condition, nano material could be covered on the board of ceramics through directly attached and naturally dried to achieve the function of the antiseptic and algae-removing. Experimental result revealed that thickness of nano-covered material is approximately 100nm. After 1000 times washing and brushing of sponge, thickness of nano-covered material is still nearly 80-90nm. On the antiseptic test aspect, when we took 18 hours to cultivate colon bacillus, the porosity ceramics covered with nano particle material can decrease fungus from 4.93´109 (cfu/mL) to 1.94´105(cfu/mL), completely attaining 99.99% rate of antiseptic. The porosity ceramics covered with nano particle material put into a fish tank, which is full of green algae. Sixty hours later, it could effectively eliminate algae growth in the fish tank and turn into clearness of water quality. With such a technique, porosity ceramics could be done with various accessories; consequently, it could be implemented for aquatic industries; additionally, it is appropriate to view and admire algae-removing fish tank.
