Effects of nanofillers and sample dimensions on the mechanical properties

of injection-molded polylactide nanocomposites (in English)

Summary

Montmorillonite nanofillers (Cloisite 30B and Nanofil 2), added in the amounts of 3 and 5 weight parts to 100 weight parts of polylactide matrix, negligibly change mechanical properties of the resulting nanocomposites under the preparation conditions applied. Poly(ε-caprolactone), added in the amount of 20 weight parts, considerably reduces tensile strength of the nanocomposites and its use is justified only when the impact strength of the products has to be increased. The sample thickness (the values of 2 and 4mm were used, according to operative standards) significantly determines the tensile strength, tensile stress at break, and tensile strain at maximal stress of the material.


Key words: nanocomposites, polylactide, mechanical properties, sample thickness
