研究目的
Investigating the thermal and morphological properties of bismaleimide modified zinc oxide nanoparticles (BMI/ZnO) through FT-IR, TG, XRD, and SEM analyses.
研究成果
The FT-IR spectrum confirmed the chemical reaction between amine groups of siliconized ZnO nanoparticles and BMI through a nucleophilic (Michael) addition reaction. Thermal analysis showed an endothermic peak at 225.02 °C and an exotherm at 264.210 °C, confirming the addition reaction. XRD and SEM images indicated nanoparticles with diameters in the range of 25-40 nm and heterogeneous morphology due to low shear stress.
研究不足
The study notes that the aggregates of bismaleimide modified siliconized zinc oxide nanocomposites are heterogeneously distributed due to low shear stress and processing time, which do not make an exfoliated material.
1：Experimental Design and Method Selection:
The study involved the synthesis of bismaleimide modified siliconized zinc oxide nanoparticles in chloroform, followed by characterization using FT-IR, TG, XRD, and SEM.
2：Sample Selection and Data Sources:
Zinc oxide nanoparticles were synthesized from zinc acetate dihydrate and ethanol, then modified with γ-Aminopropyltriethoxysilane (γ-APTS) to produce siliconized zinc oxide nanoparticles. Bismaleimide was synthesized and reacted with siliconized zinc oxide nanoparticles to produce BMI/ZnO nanoparticles.
3：List of Experimental Equipment and Materials:
Shimadzu-1800S spectrophotometer for FT-IR, Perkin Elmer TGS-2 model thermal analyzer for TG, Bruker AXS D8 advance powder X-ray diffractometer for XRD, and JSM-5610 scanning electron microscope for SEM.
4：Experimental Procedures and Operational Workflow:
The synthesis processes involved refluxing, centrifugation, and drying under vacuum. Characterization techniques included FT-IR spectroscopy, thermal analysis, XRD, and SEM imaging.
5：Data Analysis Methods:
The data were analyzed to determine the chemical reactions, thermal stability, particle size, and morphology of the nanoparticles.
