@inproceedings { , title = {Using contact angle measurements for determination of the surface free energy of the ceramic membranes.}, abstract = {The surface free energy is one of the factors that characterises the surfaces of materials. The sessile drop method is the most popular method for determining its value. A contact angle between the surface and the edge of liquid droplets is measured in this scenario. The substrate surface free energy was frequently determined using contact angle measurements for unique liquids. As shown in Table 1, contact angles were evaluated at room temperature with a model liquid (water) for all samples. It's important to note that a smaller contact angle indicates a solid's wettability (Ali, 2012). As a result, a higher contact angle indicates less model liquid absorption by the sample and consequently less interaction between the two. The largest contact angle was seen with the 200nm ceramic membrane sample, and the lowest contact angle was observed with the 15nm ceramic membrane sample. Apart from 200nm ceramic membrane sample, the DIM contact angles of the samples are quite near to each other. Scanning electron microscopy (SEM) examination was used to characterise the ceramic membrane. The ceramic membrane has a porous, rough morphological feature apart from 15nm pore size ceramic membrane appeared to have smooth on its surface. A close examination of the image reveals that the membrane was free of defects such as pinholes and cracks.}, conference = {2022 TechConnect world innovation conference and expo}, isbn = {9798218002381}, note = {INFO COMPLETE (Info via contact 20/6/2022 LM) PERMISSION GRANTED (need to request unlocked Pdf from publisher see email in Publication Inbox/Publishers/Archiving policies folder and sent to Sarah Wenning at wenning@techconnect.org 23/6/2022 LM) DOCUMENT READY (VOR rec'd from publisher 21/6/2022 LM) ADDITIONAL INFO - Contact: Edward Gobina; IDRIS HASHIM; FLORENCE AISUENI; PRISCILLA OGUNLUDE; MUKTAR RAMALAN, EVANS OGOUN; MAMDUD HUSSAINI Set Statement: © 2022 TechConnect http://techconnect.org.
