Effect of spatial distribution of wax and PEG-isocyanate on the morphology and hydrophobicity of starch films

•Synchrotron-FTIR showed the distribution of wax and PEG-isocyanate across the film.•Wax and PEG-isocyanate distributions and film surface altered the film's hydrophobicity.•High contact angle occurred when PEG-isocyanate was concentrated in the middle of the film.•Hydrophobic films possessed h...
