The difference of the performance between corn and cassava starch caused by the different content of amylose and
amylopectin were studied contrastively. Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter
(DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), X-ray photoelectron spectrometer (XPS), scanning
electron microscopy (SEM) and bonding strength were characterized to analyze the difference between corn starch and cassava
starch. The results showed that: Both the dry and wet bonding strengths of cassava starch adhesive were higher than that of
corn starch. The FTIR results indicated that the number of hydroxyl groups in corn starch structure was higher than that
in cassava starch. According to the TGA analysis, the thermal stability of corn starch and cassava starch showed unclear
difference, but the residual mass of corn starch was higher than that of cassava starch. XPS data demonstrated that the content
of carbon in corn starch was slightly higher than that in the cassava starch. According to the characterization of SEM, the corn
starch exhibited an irregular shape while the cassava starch particles were oval.
