Preparation of chitin nanofibril/polycaprolactone nanocomposite from a nonaqueous medium suspension

► Chitin nanofibril can be well dispersed in 2,2,2-trifluoroethanol. ► The well dispersed chitin nanofibril/polycaprolactone nanocomposites were prepared. ► The nanocomposites exhibited reinforced mechanical properties.
