抄録

Polymeric composites, i.e. epoxy resin and polystyrene including an ionic liquid of BMImBF4 have been prepared and characterized in terms of their tribological properties. The addition of BMImBF4 up to 20 wt% has achieved to improve lubricity of the polymeric matrices in both air and vacuum without detrimentally degrading mechanical strength. BMImBF4 has been stored in pores distributing inside the polymeric matrices. As little chemical reaction between epoxy resin and BMImBF4 has revealed by Fourier transform infrared spectroscopy, BMImBF4 would work as a lubricant after seeping from the pores due to the transformation and/or the slight wear of the surface of the polymeric composites. Furthermore, coatings of the epoxy resin including BMImBF4 on silicon plates have shown low frictional properties regarding thickness raging from several to 600 μm. The coating has also performed self-lubrication on acrylic resin as well as steel previously coated with epoxy resin to avoid chemical reaction with BMImBF4.
