How Clean is Your Surface? Surface Free Energy as a Measure of Cleanliness

Originally Aired:

Date: April 27, 2023

Abstract:

In manufacturing and fabrication processes, contamination can impede downstream processing and result in increased production times and material waste. Therefore, it is essential to track the cleanliness of surfaces throughout manufacturing.

Previously, we discussed how contact angle measurements can provide a quick and cost-effective means of quantitatively evaluating the cleanliness of a surface. In this follow-up webinar, we will expand upon contact angle measurements and demonstrate how surface free energy (SFE) can also be used to evaluate surface cleanliness.

We will discuss:

  • What is SFE?
  • How it can be determined from contact angle measurements
  • How it can provide additional information about the cleanliness of a surface compared to contact angle measurements alone
