The study of using of nanofillers in polyolefinic matrix - DSpace UTB

6. AIMS OF WORK
Tomas Bata University in Zlín, Faculty of Technology
The preparation of nanocomposites is difficult. Polymeric materials, nanofillers,
compounding device and condition of preparation can influence the properties of
nanocomposites. The type of nanofillers and their concentration can influence final properties
of nanocomposites.
PhD study was focused on the choose of optimal polymeric materials and new types of
nanofillers. Polyethylene and polypropylene were used as two materials in the first phase of
work. The data from mechanical tests and morphology leads to the polypropylene using in the
following study.
PhD study is focused on following aims:
� Preparation of packaging materials based on polyolefin/clay, study of morphology,
mechanical and barrier properties
� Usu of kneader Brabender for preparation of nanocomposites at variable condition of
preparation and concentration of nanofiller
� Comparison of commercial nanofillers and composites filled with micronized calcium.
Composites prepared at the same conditions
� Application of mathematic model for description of mechanical properties of prepared
nanocomposites
� Determination of optimal concentration of nanofiller, compounding device and
condition of preparation
