Nanofiller composites preparation

A method for synthesizing nano-aluminum hydroxide with an ATH core and alkyl hydrocarbon chain shell structure has been described.94 In the resulting composites prepared using EVA, mechanical properties of the nanofilled material were almost the same as a conventional 1 pm sized ATH variant however, the HRR of the former composition was markedly lower. In this work 10 phr of filler was used. 

Mostly nanofilled PP is produced by injection molding however, composites prepared from iPP and sPP, respectively, and organic layered silicate by the spinning procedure have been reported. ... 

A major aim to prepare the polymer-nanofiller composites is to enhance the thermal stability of the materials. The thermal properties of polymer nanocomposites are usually evaluated by differential scanning calorimetry (DSQ and thermogravimetric (TG) analyses. From DSC and TG testing, the glass transition temperature (Tg) and decomposition temperature can be determined, from which the thermal properties of polymer nanocomposites can be evaluated. 

Improving the mechanical performance of the polymer is an important target of preparing the polymer-nanofiller composites. The storage modulus is one of... 

Rubber-based nanocomposites were also prepared from different nanofillers (other than nanoclays) like nanosilica etc. Bandyopadhyay et al. investigated the melt rheological behavior of ACM/silica and ENR/silica hybrid nanocomposites in a capillary rheometer [104]. TEOS was used as the precursor for silica. Both the rubbers were filled with 10, 30 and 50 wt% of tetraethoxysilane (TEOS). The shear viscosity showed marginal increment, even at higher nanosilica loading, for the rubber/silica nanocomposites. All the compositions displayed pseudoplastic behavior and obeyed the power law model within the experimental conditions. The... 

Carbon-based polymer nano composites represent an interesting type of advanced materials with structural characteristics that allow them to be applied in a variety of fields. Functionalization of carbon nanomaterials provides homogeneous dispersion and strong interfacial interaction when they are incorporated into polymer matrices. These features confer superior properties to the polymer nanocomposites. This chapter focuses on nanodiamonds, carbon nanotubes and graphene due to their importance as reinforcement fillers in polymer nanocomposites. The most common methods of synthesis and functionalization of these carbon nanomaterials are explained and different techniques of nanocomposite preparation are briefly described. The performance achieved in polymers by the introduction of carbon nanofillers in the mechanical and tribological properties is highlighted, and the hardness and scratching behavior of the nanocomposites are also discussed.
