In the present study, plant fiber foam materials have significant differences in density compared to conventional plastic foam materials. In view of the current problems of fiber foam materials, the montmorillonite (MMT) organically modified by octadecyl-dimethyl-benzyl-ammonium chloride (ODBA) was added to the preparation of composite foam materials by optimizing the existing formula. The properties of organic montmorillonite (OMMT) and the prepared composite foam materials were characterized by scanning electron microscopy (SEM), X-ray diffractometry (XRD), and a standing wave tube sound absorption tester. The results showed that the pore size inside the plant fiber foam materials with the addition of OMMT was more uniform and arranged more closely and orderly. In addition, when the OMMT was added to 0.1 g, the density of the prepared OMMT-bagasse composite foam materials reached its lowest point of 0.079 g/cm3, which was shared with high foam materials.

The silver nanoparticles are gaining extensive attention due to their tremendous applications in conductive field. In this article, we reported a green method of preparing silver nanoparticles (AgNPs) with bagasse pulp extract acting as reducing agents. In this article, ultrasonic extraction method was adopted. This extraction method has the advantages of simple operation and less impurity content in the extract. Silver nitrate (AgNO3) solution, bagasse extract, and polyvinyl pyrrolidone (PVP) were used as the silver precursor, reducing agent, and protection agent, respectively. Next, hyperbranched polyurethane acrylate (HPUA) as waterborne resin was mixed with AgNPs to prepare UV‐curable conductive ink. The UV‐curable conductive ink synthesized by the AgNPs showed high conductivity, and the obtained conductive ink had very low resistance (1.06 Ω) and resistivity (2.6 × 10−5 Ω·m), good electronic stability, showing the great advantage in the field of UV‐curable conductive ink. In addition, we tested the AgNPs conductive ink of tearing resistance, rubbing fastness, and bending strength. The results showed the nanosilver conductive ink had good mechanical properties. J.
