Sažetak
Polylactide (PLA) composites with carbon based fillers were prepared by melt mixing method using Brabender mixer. Graphite flakes (CA), amorphous graphite (CB) (both micro fillers) and multiwall carbon nanotubes (MWCNT) (nano filler) were used. PLA composites were prepared by adding 0.1, 0.5, 1.0, 5.0 wt. % of each filler. Non-isothermal crystallization kinetics and melting behavior of PLA composites was investigated by differential scanning calorimetry while morphology of composites and dispersity of filler was investigated using scanning electron microscopy (SEM). The obtained kinetic data were analyzed by Avrami’s kinetic model. CA and CB filler hindered melt crystallization of PLA. MWCNT in PLA-MWCNT composites slightly decreased melt crystallinity of matrix from 18.7 to 14.3 % compared to neat PLA (19.9 %), except in composite with 5 wt. % of MWCNT (20.2 %). Kinetic of cold crystallization of PLA composites with CA and CB filler was slower than cold crystallization of neat PLA regardless of amount of filler. Additionally, influence of type and amount of filler on thermal conductivity of PLA composites was investigated using transient hot wire method. All composites exhibited increase of thermal conductivity compared to neat PLA. The highest thermal conductivity, registered in PLA CA5 composite, is 2.6 fold higher than that of neat PLA.
