現今工業上的油污水與原油洩漏,不僅導致了環境與生態的破壞,同時也間接影響了人體健康。因此如何解決油污染,已是迫切需要關注的,油/水分離是必須受重視的研究。
  本實驗將聚二甲基矽氧烷(Polydimethylsiloxane;PDMS)/美耐皿海綿作為油/水混合液分離過濾材,將不同種類的有機溶劑進行油/水混合液分離及使用Iso-octane進行酸鹼、仿海水與耐用性的油/水分離測試。藉由壓縮PDMS/美耐皿海綿,進行不同種類有機溶劑的無乳化劑與有乳化劑的乳化液分離,並以有乳化劑的乳化液Iso-octane進行連續分離大量乳化液與重複使用性測試,以上的各種測試皆能以高流速達到高分離效率。

In this paper, we present a facial method for the fabrication of a superhydrophobic and superoleophilic melamine sponge. We anchored the hydrophobic polydimethylsiloxane (PDMS) coatings onto the sponge to change its wettability from hydrophilic to superhydrophobic. The as-prepared superhydrophobic sponge absorbed a broad variety of oils and organic solvents with high selectivity. Because of its durable superhydrophobicity, this sponge could be used in conjunction with a vacuum system for the continuous absorption and removal of oil pollutants from water surfaces. Moreover, this superhydrophobic sponge could realize a fast oil/water separation in the harsh environmental conditions (such as different pH values and high concentration of salt). Most interestingly, we found that the compressed PDMS coated melamine sponge could separate both surfactant-free and -stabilized water-in-oil emulsions with high separation efficiency. The excellent performance of the superhydrophobic sponge suggests that it has potential applicability in both academic and industrial settings.
