The obtained self-assembled monolayers were characterized with water contact angle goniometry, auger electron spectroscopy and X-ray photoelectron spectroscopy. 使用接触角、俄歇电子能谱及X射线光电子能谱等方法进行表征。
A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry is derived from two Greek words, gōnia, meaning angle, and metron, meaning measure.
The first description of a goniometer, derived from the Astrolabe, was apparently in 1538, by Gemma Frisius.
