Effect of titanate coupling agent on the mechanical, thermal, dielectric, rheological, and morphological properties of filled nylon 6

Abstract

Fillers are used along with various commodity as well as engineering polymers to improve the properties of polymers. The performance of filled polymers is generally decided on the basis of the interface attraction of filler and polymers. Fillers of widely varying particle size and surface characteristics are responsive to the interfacial interactions with polymers. The present study deals with the effect of a coupling agent, tetra isopropyl titanate (TPT), on the properties of flyash filled nylon 6. It is observed that tensile strength, impact strength, and heat distortion temperature improved with the addition of TPT as compared to without the coupling agent filled nylon 6.

Review of titanate coupling agents and their application for dental composite fabrication

“…This reaction results in the formation of an organic titanium monolayer on the filler surface to increase the compatibility of the filler/matrix interface. The nature of the interlayer between the filler and polymer matrix introduced by titanate treatment is important in improving the mechanical properties of the composite 45) . New-generation TCAs are reportedly user-friendly, easy to incorporate with high-aspect ratio fillers, and eliminate filler pretreatment during processing.…”

“…Numerous studies indicate that TCAs provide good interfacial bonding, improve mechanical properties, enhance homogeneous filler dispersion, and modify the rheological behavior of composites 2,9,45,46,[56][57][58][59][60] . Thus, titanate adhesion promoters allow higher filler loading of particulate matter to either improve the properties or decrease the cost of the system without adversely affecting its viscosity.…”

“…Thus, titanate adhesion promoters allow higher filler loading of particulate matter to either improve the properties or decrease the cost of the system without adversely affecting its viscosity. Bose and Mahanwar 45) conducted a study to determine the effect of the TCA on the properties of fly-ash-filled nylon 6. Their group concluded that the increase in viscosity with the increase in filler content is due to the restricted molecular motion in the matrix caused by the agglomeration of the particles.…”

Effect of surface modification of fly ash on the mechanical, thermal, electrical and morphological properties of polyetheretherketone composites

“…This thermal waste has received considerable attention in the recent years as an additive component in the polymer composites. Fly ash is fine and powdery in nature with the particles essentially spherical in nature [15,16]. Fly ash filled polymer matrix composites have been studied by various workers [17][18][19][20] to improve the bulk properties of the matrix polymer predominately and have driven high volume applications.…”

Thermal and rheological behavior of ultrafine fly ash filled LDPE composites

“…Moreover the use of ultrafine particles (<10 lm), significantly affects the properties of composites due to the large specific surface of particles. 8 The fly ash is a by-product obtained by combustion of coal in thermal power plants. It is driven away from the boiler by the gases and extracted out from them by mechanical collectors or electrostatic precipitators or a combination of both.…”
