We explored the effect of poly(L-lactic acid) (PLLA) containing various percentages (0.1, 0.5, 1, and 3 wt.%) of multi walled carbon nanotubes (MWCNTs) on the myogenic differentiation of C2C12 murine myoblast progenitor cells. We showed that all PLLA/MWCNTs nanocomposite materials support the myotubes formation more efficiently than neat PLLA as indicated by the high expression of the most significant myogenic markers: MyoD, Myosin Heavy Chain, dimension of myofibres, and fusion myogenic index. Interestingly, we note that both MyoD and myogenic fusion index levels were in the order 0.1 MWCNTs = 0.5 MWCNTs > 1 MWCNTs > 3 MWCNTs > neat PLLA, suggesting that the amount of MWCNTs influenced the cell differentiation.

Walled Carbon Nanotubes

Nanocomposite materials based on a cold-cure silicone mixture containing multi-walled carbon nanotubes were obtained. The concentration dependences of the radio-physical properties of materials were investigated. An increase in the efficiency of shielding electromagnetic radiation in the radio frequency range of wavelengths with increasing concentrations of multi-walled carbon nanotubes up to 10 wt. % was verified.

Walled Carbon Nanotubes

Composites based on multi-walled carbon nanotubes (MWCNTs)s and poly(L-lactide) (PLLA) were prepared by using solvent casting method. Both carboxylated MWCNTs and pristine MWCNTs were considered in order to investigate the interactions between PLLA and MWCNTs and to understand the role of the filler in the biodegradability. In vitro degradation studies were performed by measurement of weight loss, FT-IR, DSC and SEM over a 30 weeks period. Pristine MWCNTs and carboxylated MWCNTs had a different effect on the degradation of PLLA. Thermal properties of MWCNTs based PLLA composites changed compared to neat PLLA. A possible mechanism of MWCNTs effect on the degradation of PLLA was discussed.

AbstractCarbon nanotubes (CNT) are interesting candidates for the reinforcement in robust composites and for conducting fillers in polymers due to their fascinating electronic and mechanical properties. For the first time, we report the incorporation of multi walled carbon nanotubes (MWNTs) into silica-glass surfaces by means of partial surface-melting caused by a continuous wave Nd:YAG laser. MWNTs were detected being well incorporated in the silica-surface. The composites are characterized using scanning electron microscopy (SEM) and Raman-spectroscopy. A model for the composite-formation is proposed based on heatabsorption by MWNTs and a partial melting of the silica-surface.
