In order to achieve the in-situ compatibilization of PP and other polymers, we must firstly achieve the functionalization modification of PP.

要实现PP与其它极性聚合物的原位相容，必须首先对PP功能能团化改性。

In Chattanooga, Tenn. the industry includes something very different: ESpin Technologies, a 19-employee outfit that makes nanofibers--filaments of polyester, nylon or other polymers that are only 20 to 200 nanometers wide.

FORBES: Back on Track

Belcher's colleague Paula Hammond, an expert in making highly ordered, self-assembling polymers and other materials, created a pattern of tiny posts, onto which the researchers deposited several layers of polymers that act as the battery's electrolyte.
