Abstract

<abstract> <title> <x content-type="archive" xml:space="preserve">Abstract</x> </title> <p>In this study, mesoporous materials-41 were synthesised at room temperature using a cationic surfactant cetyltrimethylammonium bromide as the template agent. Then, the mesoporous materials-41/unsaturated polyester resin materials were prepared by <italic>in situ</italic> polymerisation with the mesoporous MCM-41. Then, mesoporous materials-41/unsaturated polyester resin <italic>in situ</italic> composites were prepared by roller, milling and molding processes. The effects of the mesoporous materials-41 on the mechanical and electrical properties of the mesoporous materials-41/unsaturated polyester resin composites were investigated. The results show that the mesoporous materials-41 had a diameter in the range of 4–5 nm and the pores were highly ordered. The mechanical and electrical insulation properties of composites were improved by the addition of mesoporous materials-41. For instance, the impact strength and flexural strength of composites were increased by 29·6 and 25·25% at 2 wt-% mesoporous materials-41 loading, respectively.</p> </abstract>
