“…A correlated decrease in both degradation temperature and isoconversional activation energy has also been reported in a number of other papers. Erceg et al have seen such an effect in the thermal degradation of poly(ethylene oxide)–lithium montmorillonite nanocomposites. Papageorgiou et al have observed it when studying the thermal degradation poly(butylene succinate) (PBSu) nanocomposites containing either mesoporous strontium hydroxyapatite nanorods or silica nanotubes.…”

This article surveys the decade of progress accomplished in the application of isoconversional methods to thermally stimulated processes in polymers. The processes of interest include: crystallization and melting of polymers, gelation of polymer solutions and gel melting, denaturation (unfolding) of proteins, glass transition, polymerization and crosslinking (curing), and thermal and thermo-oxidative degradation. Special attention is paid to the kinetics of polymeric nanomaterials. The article discusses basic principles for understanding the variations in the activation energy and emphasizes the possibility of using models for linking such variations to the parameters of individual kinetic steps. It is stressed that many kinetic effects are not linked to a change in the activation energy alone and may arise from changes in the preexponential factor and reaction model. Also noted is that some isoconversional methods are inapplicable to processes taking place on cooling and cannot be used to study such processes as the melt crystallization.

This chapter deals with the fundamental properties of polymer nanocomposites (PNC) and their characteristics that play a significant role in deciding their capability for the advanced energy storage device. The various synthesization methods used for the preparation of the polymer electrolytes are described followed by the characterization techniques used for the analysis. The properties of the polymer host, salt, nanofiller, ionic liquid, plasticizer and nanoclay/nanorod/nanowire are described. Various ion transport mechanism with different nanoparticle dispersion in polymer electrolytes are highlighted. The various important results are summarized and a pathway is built to fulfill the dream of the future renewable source of energy that is economical and environmental benign. Chapter motivation is focused on the investigation of the role of polymer host, aspect ratio, surface area, nanoparticle shape and size in terms of boosting the electrolytic/electrochemical properties of PNC. It will certainly help in order to open new doors toward the development of the advanced polymeric materials with overall balancing property for enhancement of the fast solid state ionic conductor which would be revolutionized the energy storage/conversion device technology.

“…Moreover, they can be directly incorporated in the polymer matrix, thus forming polymer-clay nanocomposites. Montmorillonite is hydrophilic, as such, polymers like poly(ethylene oxide) [5] and poly(vinyl alcohol) [6,7] are archetype materials to be incorporated to the clay mineral in their pristine state. This work aimed to demonstrate that Mt can also be modified with hydrophobic organic compounds to make it compatible with other hydrophobic polymers, like poly(ε-caprolactone) (PCL).…”

Abstract. The simple cation-exchange preparation of 12-aminolauric acid-modified montmorillonite (ALA-Mt), an aluminosilicate clay modified with the alkylammonium surfactant, is reported. Different loadings of 12-aminolauric acid (12-ALA) from 100 to 400 times the cation exchange capacity (CEC) in montmorillonite (Mt) was prepared and studied. Successful intercalation of the organic surfactant was monitored by the increase in basal (d001) spacing of the organoclay compared to the pure Mt. The clay mineral composite have increased surfactant loading resulting to lower degradation temperatures, rougher surface morphology, increased particle size, and increased organophilicity of the organoclay compared to the native Mt. The improved properties of ALA-Mt present it as an attractive catalyst material for polymerization reactions.
