Abstract
Truly single layer (monolayer) films of unmodified zigzag single-walled carbon nanotubes by using the Langmuir-Blodgett (LB) technique have been processed successfully. Measurements of their mechanical and optoelectric properties were achieved. Different theoretical equations were used based on the results obtained from the experimental part to study the properties and structures of the produced material and their composite. The produced films were highly oriented as determined by polarized Raman spectroscopy and as shown by scanning tunneling microscopy (STM). The films have a significant amount of flexibility which makes their behavior similar to rubbery materials. They can also be deposited on different types of substrates with different shapes depending on the required applications. Nanocomposites utilizing Poly (methyl methacrylate)-(PMMA) matrix were also prepared and characterized. Both direct mixing and in-situ polymerization techniques were employed to investigate the effect of mixing method on the produced composite properties. In addition to that, a comparison process between the theoretical models which were used to estimate the composite modulus with the experimental results for direct mixing method of the composite is applied with emphasizing the effect of the interphase factor on the empirical calculated composite modulus values.
