The potential impact of light-weight structures with multifunctional properties for engineering applications drives significant research and development activities on nanocomposites. Polymer nanocomposites especially those with carbon nanotubes (CNTs) are very attractive for conductive composites with good structural characteristics. The biggest challenge facing the commercial success of CNT based composites is the intrinsic strength of their agglomerates which prevents good filler dispersion in the matrix, a key attribute for any reinforcement. This chapter is a review of the CNT incorporated thermoplastic composites processed mainly containing economic multi-walled carbon nanotubes (MWCNTs). We present an overview of CNTs (their structure, production process, properties, surface modification, applications etc.) and the mechanism of their dispersion in thermoplastic matrices. The processing of thermoplastic matrices via the conventional twin-screw compounding approach is discussed along with the influence of process parameters on MWCNT dispersion. The role of secondary processing operation on composite properties is also highlighted. The mechanical, electrical and thermal properties of the thermoplastic-CNT composites are reviewed highlighting the key findings and shortcomings. We conclude throwing some light on the developments on multi-scale reinforcements in polymeric matrices.

A high-performance electromagnetic susceptibility (EMS) of plastic transceiver module using carbon nanotube (CNT) composites is proposed. The shielding effectiveness (SE) of the CNT composites increases as the weight percentage of the CNTs increases. The SE of CNT composites with 50% weight percentage CNTs exhibits 38-45 dB. The EMS performance is experimentally evaluated by the eye diagram and bit-error-rate test for a 2.5-Gbps lightwave transmission system. The results show that the eye diagram and power penalty caused by the radiated interference of the plastic transceiver modules are dependent on the EMS. The plastic transceiver modules with the more weight percentage of the CNTs exhibit a higher SE, and hence show effective EMS performance, a better mask margin, and a lower power penalty. The likely cause for effective EMS performance with higher weight percentage CNTs of the plastic transceiver modules is due to the high-aspect ratios of CNTs, more structural to form overlapping conductive networking to provide high SE. Therefore, the CNT composites with their high SE are suitable for packaging high-performance EMS optical transceiver modules used in fiber to the home (FTTH) lightwave transmission systems. Index Terms-Carbon nanotube (CNT), electromagnetic interference (EMI), electromagnetic susceptibility (EMS), plastic optical transceiver modules, shielding effectiveness (SE).

Because of their extraordinary properties, such as high thermal stability, flame retardant, high chemical resistance and high mechanical strength, thermotropic liquid crystalline polymers (TLCPs) have recently gained more attention while being useful for many applications which require chemical inertness and high strength. Due to the recent advance in nanotechnology, TLCPs are usually compounded with nanoparticles to form particulate composites to enhance their properties, such as barrier properties, electrical properties, mechanical properties and thermal properties. Carbon-based nanofillers such as carbon nanotube (CNT), graphene and graphene oxide are the most common fillers used for the TLCP matrices. In this review, we focus on recent advances in thermotropic main-chain liquid crystalline polymer nanocomposites incorporated with CNTs. However, the biggest challenges in the preparation of CNT/TLCP nanocomposites have been shown to be inherent in the dispersion of CNTs into the TLCP matrix, the alignment and control of CNTs in the TLCP matrix and the load-transfer between the TLCP matrix and CNTs. As a result, this paper reviews recent advances in CNT/TLCP nanocomposites through enhanced dispersion of CNTs in TLCPs as well as their improved interfacial adhesion with the TLCP matrices. Case studies on the important role of chemically modified CNTs in the TLCP/thermoplastic polymer blends are also included. OPEN ACCESSPolymers 2012, 4 890
