界面调控MXene及其对硅橡胶力学-电学性能的协同增强研究
Research on Interface Regulation of MXene and Its Synergistic Enhancement of Mechanical-Electrical Properties of Silicone Rubber
摘要
Abstract
The silicon rubber/two-dimensional transition metal carbonitrides(MXene)composites were prepared via mechanical blending method.MXene was first subjected to surface organic modification to improve its compatibility with the silicon rubber matrix,achieving uniform dispersion and intimate interfacial bonding of MXene within the matrix.Microstructural analysis indicated that strong interactions were formed between the modified MXene and silicon rubber.When the addition level of polyvinylpyrrolidone-modified MXene(PVP-MXene)was 0.50 phr,the composites exhibited optimal comprehensive mechanical properties,with a tensile strength of 6.1 MPa,a tear strength of 14.6 N/mm,and an elongation at break of 228%.The MXene nanosheets effectively restricted molecular chain mobility and facilitated stress transfer.The composites also demonstrated significant electrical conductivity,which increased with rising modified MXene content,showing potential for applications in electromagnetic shielding and flexible electrodes.关键词
