在许多应用领域,含“纳米”的产品已走出实验室,来到了用户面前。但是纳米纤维的应用面还相对十分狭窄,工业上纳米纤维产品大都与过滤有关。目前用户拿到的都是直径限于2～5μm以上的超细纤维产品。尽管只要每根纤维直径均在1000 nm以下的就可称之为纳米纤维,但最为普遍接受的纳米纤维的界限要求是直径在500 nm以下。纳米技术不能在更多领域采用的理由之一与以前的生产技术有关。在过去,生产技术
In many applications, products containing “nano ” have come out of the laboratory, came to the user. However, the application of nanofibers is still relatively narrow surface, the majority of industrial nanofiber products and filtration. At present, users get the diameter of more than 2 ~ 5μm superfine fiber products. Although nanofibers can be called as long as each fiber diameter is below 1000 nm, the most commonly accepted nanofiber boundary requirement is below 500 nm in diameter. One of the reasons why nanotechnology can not be used in more fields is related to previous production techniques. In the past, production technology
