be hydrophobic
be hydrophobic 描述物质不易被水润湿,常用于化学和材料领域。
This surface is hydrophobic, so water forms beads on it instead of spreading.
这个表面是疏水的,所以水会在上面形成水珠而不是铺开。
疏水的;憎水的
先理解核心含义,再看它在真实句子里的用法。
疏水的;憎水的
Lacking affinity for water; tending to repel or not absorb water.
This surface is hydrophobic, so water forms beads on it instead of spreading.
这个表面是疏水的,所以水会在上面形成水珠而不是铺开。
属于或患有狂犬病的;患狂犬病的。
Of, or having, hydrophobia (rabies); rabid.
对水缺乏亲和力;不能吸收水或不能被水润湿。
Lacking an affinity for water; unable to absorb or to be wetted by water.
This coating is hydrophobic, so water rolls right off the surface.
这种涂层是疏水的,所以水会直接滚落表面。
The leaves of the lotus are hydrophobic and stay dry in the rain.
荷叶是疏水的,下雨时保持干燥。
Scientists developed a hydrophobic fabric for outdoor jackets.
科学家为户外夹克研发了一种疏水面料。
be hydrophobic 描述物质不易被水润湿,常用于化学和材料领域。
This surface is hydrophobic, so water forms beads on it instead of spreading.
这个表面是疏水的,所以水会在上面形成水珠而不是铺开。
hydrophobic 作定语时通常修饰 surface、coating、molecule 等名词,表示“疏水的”。
The hydrophobic coating keeps the lens dry in the rain.
疏水涂层让镜片在雨中保持干燥。
此义指“异常怕水”,仅用于医学描写,尤其与狂犬病有关。
A person with advanced rabies may become hydrophobic and unable to drink.
狂犬病晚期的人可能会出现恐水症状,无法喝水。
Not this
This jacket is hydrophobic, so it keeps me dry in the rain.
Use this
This jacket is waterproof, so it keeps me dry in the rain.
hydrophobic(疏水的)是化学/材料学用语,指物质在分子层面不亲水、不易被水润湿,并不等于日常所说的“完全防水”。要表达衣物能挡住雨水、保持干燥,应用 waterproof(防水的)。
Not this
Oil is hydrophobic to water.
Use this
Oil is hydrophobic.
hydrophobic 本身就含有“怕水、不溶于水”的意思,后面不能再接 to water。中文可以说“对水是疏水的”,但英语中 hydrophobic 是绝对形容词,不搭配介词,应删除 to water。
Not this
The hydrophobic of this material is very strong.
Use this
The hydrophobicity of this material is very strong.
hydrophobic 是形容词,不能直接作名词表示“疏水性”。表示“疏水性”这个特性时,要用名词 hydrophobicity,因此把形容词改成名词。
Focus on the distinctions below. Other candidates are kept compact until a reliable usage note is available.
疏水表面
The lotus leaf has a naturally hydrophobic surface.
荷叶具有天然的疏水表面。
疏水材料
Water beads up on this hydrophobic material.
水在这种疏水材料上会结成水珠。
疏水效应
The hydrophobic effect drives protein folding.
疏水效应驱动蛋白质折叠。
疏水相互作用
Hydrophobic interactions help stabilize the cell membrane.
疏水相互作用有助于稳定细胞膜。
疏水涂层
They applied a hydrophobic coating to the windshield.
他们给挡风玻璃涂上了疏水涂层。
Use hydrophobic naturally, then get feedback on meaning, tone, grammar, and phrasing.

hydro-与“水”相关,phobic是“恐惧”;hydrophobic即“怕水”,化学中指“疏水”,像油不沾水。
语域:formal 常见场景:chemistry、materials science、surface science 在化学和材料科学等科技语境中,hydrophobic 通常表示“疏水的、憎水的”,属于正式术语,多用于论文和实验报告;日常口语中较少单独使用,常说 water-repelling 或 waterproof。
以上单词都以 -phobic 结尾,与 hydrophobic 押韵(重读音节为 /fəʊ/ + /bɪk/)。注意形近但音异的词:hydrophobia /ˌhaɪdrəˈfəʊbiə/ 和 phobia /ˈfəʊbiə/ 结尾是 /biə/ 而不是 /bɪk/;hydrophilic /ˌhaɪdrəˈfɪlɪk/ 的词尾是 /fɪlɪk/,意思为“亲水的”,不要混淆。
