Polyethyleneimine (PEI) and chromium oxide (Cr 2 O 3 ) with different weight percentages were chosen for sensing carbon dioxide (CO 2 ). Four divergent varieties of sensors with different concentrations of Cr 2 O 3 in PEI were fabricated by drop-casting the sensitive films on prepared interdigitated...
