dc.description.abstractFourier-transform infrared spectroscopy (FTIR) is a well-known technique used to analyze the chemical composition of polymeric materials by measuring the absorption of infrared light over a range of wavelengths, where each absorption peak corresponds to a specific chemical bond. A chemical map image can be constructed by acquiring multiple IR spectra with a specified step distance over an area. Furthermore, it is possible to extract information about the molecular orientation by utilizing linearly polarized light, as the absorption intensity varies with the polarization angle of the incident radiation. Recently, a mathematical method was introduced which makes it possible to create a complete vector map of the dipole orientation of a selected vibrational mode by utilizing measurements of IR spectra in four different polarized orientation. In this work, we seek to gain insight into the molecular orientation near the interface between the disperse phase and the continuous matrix of a polypropylene-polyamide 6 (PP-PA6) blend by comparing an uncompatibilized blend with a blend compatibilized with the addition of maleic anhydride grafted polypropylene (PP-g-MA) [4] and another with the application of a novel in-situ plasma treatment. The goal of plasma treatment is to introduce polar oxygen groups such as C−O, C=O, and O−C=O, promoting stronger interactions between phases. Plasma treatment is widely used as a surface treatment to increase wettability and adhesion, but its use as a compatibilization method of blends is relatively new and has already provided positive results. However, the mechanisms behind the improvements in this context are mostly unknown so the current research will provide valuable data for further development of this novel polymer modification method. © 2023 The Authors.en_AU
