From a low cost template made of electrospun polyacrylonitrile fibers, a highly stable boron nitride nanotube (BNNT) mat is fabricated using low temperature atomic layer deposition (ALD) of BN. Based on polymer-derived ceramics chemistry, this ALD process permits preparation of high quality BNNTs that show superhydrophobicity, stability over a month in air and various pH conditions as well as excellent performances in water treatment. In particular, the obtained material presents high ability as a separation filter for oil from the aqueous phase in an immiscible mixture and emulsion. The BNNT mat also displays excellent reusability performances for absorption of various organic solvents and oils making this unwoven material highly promising for efficient water purification and treatment.

ALD氮化硼纳米管垫用于水净化的有前途的性能†

从电纺聚丙烯腈纤维制成的低成本模板，使用BN的低温原子层沉积（ALD）来制造高度稳定的氮化硼纳米管（BNNT）垫。基于聚合物衍生的陶瓷化学，此ALD工艺可制备高质量的BNNT，这些BNNT在空气和各种pH条件下在空气中可显示一个月以上的超疏水性，稳定性以及出色的水处理性能。特别地，所获得的材料作为用于从不相混溶的混合物和乳液中的水相中分离油的分离过滤器具有很高的能力。BNNT毡还具有出色的可重复使用性能，可吸收各种有机溶剂和油，这使得这种无纺布材料有望有效地进行水的净化和处理。
