Corn stalk (CS) was used as raw material to prepare biochar. Corn stalk biochar /HDPE composite (CSB/HDPE) was prepared by extrusion method with 3 wt% MA added. The effect of corn stalk biochar (CSB) on the rheological properties of HDPE under different conditions was studied. The interface performance of each component with HDPE was studied by using the Harmonic‐Mean interface equation. The purpose is to provide guidance for the processing and molding of materials by studying the rheological properties and interface properties of the materials. The results showed that, compared with CS, the interfacial tension between CSB and HDPE was lower; Research on dynamic rheological properties showed that an appropriate amount of CSB can improve the processing performance of HDPE; With the increase of CSB content, the stability of the composite system decreased, but the elasticity and viscosity increased correspondingly. The steady‐state rheological properties showed that shear induced compatibility occurs in the composite system at high shear rates; Compared with HDPE, 50 %CSB/HDPE was more sensitive to temperature and had higher viscous flow activation energy. In addition, the tensile strength and flexural strength of the composite material reached the maximum when the CSB content was 50 %, which were 28.69 MPa and 30.14 MPa, respectively. Overall, the study of rheological properties of materials provides guidance for the application of CSB in polymers and broadens the way of waste resources utilization.

“…The grain size of G-LDHs is similar to the diameter of BF and the system defects, and the boundary between the three phases becomes blurred, forming a high miscibility system. [30] The hydrotalcite will have physical or chemical reactions and agglomerate on the epoxy resin interface when the amount of G-LDHs is excessive, demonstrating a poor filling effect. Moreover, the synergistic effect with BF is destroyed, resulting in a decrease in mechanical properties of the composite material.…”

Natural fibers (NFs) and inorganic particles have been successfully grown in the polymer to enhance its properties. The basalt fiber (BF) and modified hydrotalcite (LDHs) reinforced epoxy resin matrix composites were prepared, and the effects of fiber and modified hydrotalcite (G-LDHs) on the microstructural characteristics of composites were investigated. Fourier transform infrared spectroscopy and X-ray diffraction were respectively used to analyze the structure of modified BF and G-LDHs, and thermogravimetric analysis was performed to study thermal stability. The mechanical properties of composites, including dynamic thermomechanical and tensile and flexural properties, were respectively studied by dynamic mechanical analysis (DMA) and universal testing machine. Experimental results show the successful synthesis of high-performance epoxy copolymers. The impact strength, tensile strength, and elastic modulus of EP/BF/G-LDHs respectively reached 7.07 kJ/m 2 , 20.52 MPa, and 2595 MPa when the content ratio of BF to hydrotalcite in the additive was 3:3. The DMA test showed that the glass transition temperature (T g ) value increased by 18.3 C, and the thermal stability of composite materials was improved. The storage modulus E 0 value increased by 268.04 MPa, and the stiffness of the epoxy material and the mechanical properties were also elevated. The TGA and DTG curves indicate that the cured composites also exhibit excellent thermal stability. The effect of g-LDHS particle size on the properties of composites was also discussed. Overall, the synergistic and complementary enhancement effect of the two materials is the best when the diameter of hydrotalcite is similar to that of BF, and the performance of the composite material is considerably improved.high-performance composites, mechanical properties, mechanical properties, thermal stability, thermogravimetric analysis | INTRODUCTIONEpoxy resin is one of the polymer materials with a long history and wide application.

The microstructure–property relationship in poly(methyl methacrylate) PMMA composites is very important for understanding interface phenomena and the future prediction of properties that further help in designing improved materials. In this research, field emission scanning electron microscopy (FESEM) images of denture PMMA composites with SrTiO3, MnO2 and SrTiO3/MnO2 were used for fractal reconstructions of particle agglomerates in the polymer matrix. Fractal analysis represents a valuable mathematical tool for the characterization of the microstructure and finding correlation between microstructural features and mechanical properties. Utilizing the mathematical affine fractal regression model, the Fractal Real Finder software was employed to reconstruct agglomerate shapes and estimate the Hausdorff dimensions (HD). Controlled energy impact and tensile tests were used to evaluate the mechanical performance of PMMA-MnO2, PMMA-SrTiO3 and PMMA-SrTiO3/MnO2 composites. It was determined that PMMA-SrTiO3/MnO2 had the highest total absorbed energy value (Etot), corresponding to the lowest HD value of 1.03637 calculated for SrTiO3/MnO2 agglomerates. On the other hand, the highest HD value of 1.21521 was calculated for MnO2 agglomerates, while the PMMA-MnO2 showed the lowest Etot. The linear correlation between the total absorbed impact energy of composites and the HD of the corresponding agglomerates was determined, with an R2 value of 0.99486, showing the potential use of this approach in the optimization of composite materials’ microstructure–property relationship.
