Size-Dependent in MWNTs/PDMS Composite Films

Abstract

Some equipments are required for optical limiting against laser pulses. Multi-wall carbon nanotubes (MWNTs) have exhibit perfect optical limiting property. The size-fractionation of MWNTs/polydimethylsiloxane (PDMS) films has been achieved. The Z-scan experiments and transmission measurements with 532 nm wavelength laser pulses shows that the optical limiting behavior of MWNTs/PDMS films solution is size-dependent.
