Study about Characteristics of FTIR and XRD for Corn Stalk Surface with KH-560 Treatment

The surface of corn stalk was modified by silane coupling agent KH-560 to improve corn stalk surface properties. The contact angle of the different probe liquid was determined by angle meter, from which the surface wettability of corn stalk was calculated and then the surface free energy deduced, crystallinities and compositional variation of the treated corn stalk were studied by employing XRD and FTIR. The results showed that the optimum mass fraction of silane coupling agent KH-560 was 3%, the corn stalk surface free energy was improved and crystallinities was red- uced after the treatment of silane coupling agent, functional groups spectra of strength change obviously, thus the sur- face properties of the corn stalk can be improved quickly and effectively.
