Description

Dropen is a fully automatic drop image analysis software in order to study the wetting properties of solid surfaces. It also includes the manual selection and fitting approaches. This software is developed in MATLAB using GUIDE. Regarding the identification of contact points two approaches are provided in Dropen: 1. Automatic: determines the left and right contact points automatically using a precise image processing code; 2. Manual: let the user select the left and right contact points manually by pushing the “Manual selection” button. In the case of the wrong selection of contact points the software let the user try two more times without a need to push the “Manual selection” button again. Regarding the contact angle measurement, the software provides a fully- automatic convolution mask method and also fitting with the circle and polynomial equations. So, the contact angle measurement panel includes: 1. Mask method: the fully automatic contact angle measurement, 2. Fitting: includes: a. Circle b. Polynomial: user can change the polynomial order. Regarding our studies, the optimum polynomial order for superhydrophilic droplets is two and for the rest of the droplets is Three. So, it is recommended to do not to change the polynomial order. After choosing the contact point identification and contact angle measurement methods, push the RUN button to find the results in the Result panel. In addition, the magnified images of the left and right contact areas are presented there. The drop contour line and the contact points have been shown with blue and red markers on the image, respectively. It is possible to save the contact angle data, as well as the left and right contact area images by pushing the corresponding push buttons. This software is developed in SEFILAB at the Department of Materials science, University of Milano-Bicocca, and is available at the UNIMIB repository (http://dx.doi.org/10.17632/wzchzbm58p.3). This repository will be updated by the new modified versions of the software.

Steps to reproduce

Dropen is a fully automatic drop image analysis software in order to study the wetting properties of solid surfaces. After downloading the app, run it in MATLAB. It will be added to MATLAB 'App' and you can easily use it to measure the drop contact angle on a solid surface. This software is developed in SEFILAB at the Department of Materials science, University of Milano-Bicocca. We will update this repository with the new modified versions of the software.
