纳米聚合物登上舞台

美国研究者们制成了一种新材料――纳米聚合物,一种在纳米尺度下与聚合物等同的材料。MIT的Francesco Stellacci和同行们完成了这项突破。他们向位于球形金属纳米微粒表面上两个相对的区域引入了人为的缺陷,得到的二价粒子进而链接聚合形成了独立的薄膜。

Nanopolymers make their debut (Jan 19)

Researchers in the US have made a new class of materials called "nanopolymers" -- the first nanoscale equivalents of polymers. The breakthrough was made by Francesco Stellacci and colleagues at the Massachusetts Institute of Technology and involves introducing defects onto two opposing areas on the surface of spherical-shaped metallic
nanoparticles. The resulting divalent particles are then chained together to make freestanding films (Science 315 358).
