All MATLAB codes were generated and used in MATLAB R2023b academic.

The Excel files containing keyword "PVDF" contain FTIR scan data of 3d-printed active materials. The last number in filename labels the sample number.

E.g., the data file "PVDF_TRFE_1" is gathered for 3d-printed PVDF-TrFE, sample #1. 

MATLAB code "determine_beta_content.m" is used to calculate the average beta-phase content for 3d-printed PVDF and PVDF-TrFE.


To run the program:

1) Open "determine_beta_content.m"

2) Run the code, the average beta-phase content show up in the command window. It is unit-less

The Excel document "Beta Crystalline Content Summary.xls" lists the average beta-phase content of each data file calculated by the MATLAB code.
