Description

Low-Cost Method for Determining the Surface Free Energy of Micro-particles and Nanoparticles

 

Case ID:

19/0027

 

Background

Surface free energy (SFE) of micro- and nanoparticles plays a crucial role in determining the hydrophobicity and wettability of the particles. To date, however, there are no easy-to-use methods for determining the SFE of particles.

 

Technology Overview

Researchers at the University of Hawai’i have developed the maximum particle dispersion (MPD) method, a novel technique that uses inexpensive, easy-to-use and commonly available lab procedures and facilities for quantitatively determining the SFE of micro-particles and nanoparticles.

The researchers demonstrated the versatility and robustness of the MPD method by studying nine representative particles of various chemicals, sizes, dimensions, and morphologies. The SFE of these micro- and nanoparticles was found to cover a range from 21 to 36 mJ/m2. These SFE values may find applications in a broad spectrum of scientific disciplines including the synthesis of these nanomaterials such as exfoliation.
