A simple method to direct identify nanometer sized textures in composite materials by means of AFM Spectroscopy, aiming at recognizing nanometer structures embedded in a sample. It consists in acquiring a set of dynamic data organized in spectroscopy maps and subsequently extracting most valuable information by means of the Principal Component Analysis (PCA) method. In this work we explain the main features of the method and show its application on a nanocomposite sample.

Abstract
A simple method to direct identify nanometer sized textures in composite materials by means of AFM Spectroscopy, aiming at recognizing nanometer structures embedded in a sample. It consists in acquiring a set of dynamic data organized in spectroscopy maps and subsequently extracting most valuable information by means of the Principal Component Analysis (PCA) method. In this work we explain the main features of the method and show its application on a nanocomposite sample.
