| description | BackgroundThe porosity and hole overlap rate of nuclear track-etched membrane are important parameters to characterize its filtration performance.PurposeThis paper aims to develop an analysis platform for hole distribution on the nuclear track-etched membrane surface by computer simulation, which can predict some key product parameters and help optimize process parameters in actual production.MethodsBased on the Monte Carlo method, the platform was developed using the data analysis framework ROOT. The incident ions were under the hypothesis of two-dimensional (2D) uniform distribution and holes were under the hypothesis of the same size. The 2D coordinates of holes were generated by gRandom function in ROOT, and holes on the surface were drawn in 2D pixelated binary canvas. The hole area was calculated simply by counting the number of fired pixels, and porosity was equal to the effective hole area divided by canvas area. The probability distribution of single, double, and multiple holes on the surface under different porosities was calculated according to each specific image, so was the probability distribution of the area of multiple holes. Finally, the reliability of analysis platform was verified by comparing the calculation results with the theoretical deduction results and the scanning electron microscope observation results.ResultsThe results shows that hole overlap rate and porosity satisfy a certain functional relationship, and cannot be independently controlled in production. With the increase of porosity, the probability of single hole decreases monotonously, while the probability of multiple holes continues to increase. When the porosity is 10%, the hole overlap rate is close to 35%; as the porosity increases to 30%, the hole overlap rate reaches 80%.ConclusionsIt can be concluded that this analysis platform can analyze and calculate key product parameters such as porosity and overlap rate, therefore can be used as an auxiliary tool for optimizing process parameters in the production of nuclear track-etched membranes. |
