Mechanical properties

AI Thread Summary

Research papers on the mechanical properties of spincast membranes, including tensile strength, Young’s modulus, and Poisson’s ratio, are sought for further understanding. The feasibility of spincasting a membrane measuring approximately 0.2m in diameter and 0.076mm in height is also in question. The goal is to develop a radially-oriented version of BOPET (biaxially-oriented polyethylene terephthalate). Insights into both the mechanical properties and fabrication challenges are crucial for this project. The discussion emphasizes the need for reliable data and practical guidance in spincasting techniques.

TL;DR Summary: I hope I’m posting in the correct kind of forum.

I found a ‘guide’—at least of sorts—about spincoating here: https://www.ossila.com/pages/spin-coating#choosing-a-spin-coating-method, but I have a question or two about the possibilities when it comes to spinCAST membranes.

1. Can anyone point me toward publicly-available research papers which examine the mechanical properties of spincast membranes, specifically Tensile Strength, Young’s Modulus, and Poisson’s ratio?

2. How doable might it be to spincast a membrane about 0.2m across and 0.076mm tall?

What I am hoping to is create a radially-oriented version of BOPET (biaxially-oriented polyethylene terephthalate).
