Facile Preparation of Lightweight Natural Rubber Nanocomposite Foams with High Wear Resistance

Polymers, Journal Year: 2024, Volume and Issue: 16(9), P. 1226 - 1226

The light weight and excellent mechanical properties of rubber foam means that it is widely applied in the aerospace, automobile, military industries. However, its poor wear resistance contributes directly to a short service life waste resources. Therefore, design development high-wear-resistance are great importance. In this work, some nanoclay/rubber composite foams were prepared by blending NR/EPDM with different kinds nanoclays containing layered double hydroxide (LDH), montmorillonite (MMT), attapulgite (ATP) indicate effects on foams. investigated Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction. results showed nanoclay has heterogeneous nucleation foamed materials. materials added was significantly improved, MMT lamellar structure (increased 43.35%) LDH 38.57%) higher than ATP rod-like 13.04%). improvement matrix even higher. Compared other foams, OMMT–NR/EPDM 58.89%) had best resistance. Due increase spacing modified OMMT, exfoliation worn molecular chains little effect adjacent chains, which prevents occurrence crimp further improves foaming work lays foundation for manufacturing wear-resistant applications.

Abstract The multifunctional composite elastomers serve as thermal interface materials for heat dissipation in electronic devices when their transport performance is enhanced. common method enhancement, continuously raising the conductive filler loading only can improve conductivity of but reduces compliance, resulting elevated contact resistance with solid surfaces, compromising transport. To address this, we propose grafting short dangling chains onto elastomer matrix to further promote compliance under a certain loading. Characterization results demonstrate that grafted effectively reduce relaxation time, enabling faster deformation material pressure. This approach enhances interfacial compatibility, widening path at interfaces by 94% (from 17.8 1.07 mm 2 W/K), significantly improving overall Additionally, discussed feasibility employing efficient chip dissipation. Highlight softness. softness promotion help resistance. A series theories are employed learn mechanisms promotion. be used materials.
