| Özet |
| In this study, highly flexible polymer nanocomposites that can be stretched morethan 9 times their original length were successfully fabricated by using poly[styrene-b-(ethylene-co-butylene)-b-styrene] (SEBS) and vapor grown carbonnanofibers (VGCNFs). Two different polymers were used in order to investigatethe effects of the polymer molecular weight on viscosity, morphological andmechanical properties of the samples. Mixing was carried out by a planetary highshear mixer for various levels of VGCNFs and SEBS. Nanocomposites wereprepared by the combination of solvent casting and compression molding.Viscosity measurements were carried out as a function of filler ratio for bothpolymers. Higher molecular weight and higher filler ratio led to higher viscosity.Morphological analysis showed homogeneous filler dispersion without anydominant filler orientation throughout the composites with good filler-matrixinterface and absence of any pores or voids. Filler content and matrix molecularweight were found significant for mechanical properties. The mechanicalstrength and elastic modulus of the nanocomposites increased by the addition ofVGCNF regardless of the polymer molecular weight. Nanocomposites fabricatedby using higher molecular weight polymer showed better mechanical properties.Above mentioned attributes those belong to both polymer composites meet therequirements of flexible electronics and can be used for many applicationsincluding micro-electro-mechanical systems, conductive coatings,electromagnetic shielding applications, polymeric sensors and actuators. |
