Rheological properties of composite polymers and hybrid nanocomposites

Abstract

This paper summarizes a review of the viscosimetric, viscoelastic and rheological properties of polymers and hybrid nanocomposite polymers. Hybrid nanocomposites can be combined from natural fibers or synthetic fibers and/or both. The hybrid nanocomposite polymer offers the designer the opportunity to achieve the required characteristics to a considerable extent controlled by the choice of appropriate fibers or fillers and the polymer architecture. The rheological behavior of hybrid nanocomposite depends on fiber content, fiber length, fiber orientation, fiber-to-matrix bonding, fiber configuration and filler, respectively. Further, rheological properties of hybrid nanocomposite polymers by introducing various charges were examined discussed.

Elaboration, Electrochemical Investigation and Morphological Study of the Coating Behavior of a New Polymeric Polyepoxide Architecture:

“…Polyepoxide polymeric architectures are very important thermosetting technological macromolecular matrices [1][2][3], since they have varied uses in industry, thanks to their numerous viscosimetric and rheological properties [4][5][6], such as aeronautical and spatial construction [7][8][9]. Corrosion inhibition [10] by the protection and coating of metallic objects [11] with inhibitors is important in the field of heritage conservation, due to their ease of implementation, according to their microscopic and macroscopic properties.…”

“…We tested the decaglycidyl polymer of phosphorus pentamethylene dianiline (DGPMDAP), crosslinked and formulated by natural phosphates, among the different coating types that can play an important role in the prevention of corrosion oxidation and heritage degradation [14][15]. This is due to its good adhesion, strong acid/alkali resistance and high cross-link density, according to its macromolecular structure [16][17].…”

Elaboration and Electrochemical Studies of the Coating Behavior of a New Nanofunctional Epoxy Polymer on E24 Steel in 3.5 % NaCl

“…Polyepoxide resins are very important thermosetting technological macromolecular matrices [1][2], which have been widely used in several industrial fields, such as radioactive waste conditioning [3][4], viscosimetric and rheological behavior [5-6-7], aeronautical construction [8], spatial construction [9][10], and metallic objects corrosion inhibition [11] and coating [12]. Our goal is to assess a new behavior of an E24 steel coating, which is easy to implement and inexpensive for the heritage protection subjected to standard atmospheric corrosion.…”

“…The coating method with epoxy resins remains a very effective approach to avoid rapid corrosion, because of its good adhesion, good acid/alkali resistance, and its high cross-linking density, thanks to its macromolecular structure [19]. In this work, we applied a new nanofunctional epoxy prepolymer, nanoglycidyl trihydrazine 4,4,4-tripropoxy of ethylene tribisphenol A, synthesized in the laboratory [20], on E24 steel, in marine environments. The coating impact on E24 steel was assessed by using the two E1 (NGTHTPETBA/MDA) and E2 (NGTHTPETBA/MDA/PN) protection formulations, while evaluating their anticorrosive behavior by two electrochemical methods, namely the stationary method and the transitional method.…”

Theoretical and Electrochemical Studies of the Coating Behavior of a New Epoxy Polymer: Hexaglycidyl Ethylene of Methylene Dianiline (HGEMDA) on E24 Steel in 3.5% NaCl

“…Epoxy polymers are very important technological thermosetting materials that have been widely used in several industrial fields, such as electronics [1,2], coating [3], corrosion inhibition [4], packaging of radioactive wastes [5,6], viscosimetric and rheological behavior [7,9]. They are also used as adhesives in aeronautical construction [10] and in space construction [11,13].…”
