本篇应用文献将描述接枝对材料表面的纳米形态或“纳米粗糙度”的影响，并由此详细解释这一概念。 反气相色谱 (IGC) 是一种独特的表面分析技术 ，可在细微的分子水平上测量材料表面的纳粗糙度，并更好地了解固体表面形态、其特性和/或行为。 在这里，以几种有机接枝二氧化硅为例，说明接枝对材料表面纳粗糙度的影响。

This application note is to describe the influence of grafting onto the nanomorphology or “nanoroughness” of a material’s surface and explain thereby this concept in detail.

Inverse Gas Chromatography (IGC) is a unique surface analytical technique  to measure nanoroughness on a subtle molecular level and to provide a better understanding of a solid surface morphology, its properties and/or behaviour. Here, several organically grafted silicas are used as an example to demonstrate the influence of grafting onto a material’s surface nanoroughness.
