“…Taking into account the agglomeration observed in Ag/DT/L3 samples, it was decided to neglect the analysis of the morphology of the L3 nanocomposite, without surfactant. Finally, the tensile properties of the different studied systems have been summarized and compared with the theoretical values obtained from the empirical models represented by the Guth and Gold (G-G) equation [31][32] and the Halpin-Tsai (H-T) model [33][34][35] for the tensile modulus of composite materials. Guth and Gold introduced a quadratic term on the Smallwood-Einstein equation to explain the reinforcing effect of fillers on elastomeric matrices taking into account the interactions between fillers, as shown in Equation (3):…”

Abstract. A comparative study on the self-assembled nanostructured morphology and the rheological and mechanical properties of four different triblock copolymers, based on poly(styrene-block-butadiene-block-styrene) and poly(styrene-blockisoprene-block-styrene) matrices, and of their respective nanocomposites with 1 wt% silver nanoparticles, is reported in this work. In order to obtain well-dispersed nanoparticles in the block copolymer matrix, dodecanethiol was used as surfactant, showing good affinity with both nanoparticles and the polystyrene phase of the matrices as predicted by the solubility parameters calculated based on Hoftyzer and Van Krevelen theory. The block copolymer with the highest PS content shows the highest tensile modulus and tensile strength, but also the smallest elongation at break. When silver nanoparticles treated with surfactant were added to the block copolymer matrices, each system studied shows higher mechanical properties due to the good dispersion and the good interface of Ag nanoparticles in the matrices. Furthermore, it has been shown that semiempirical models such as Guth and Gold equation and Halpin-Tsai model can be used to predict the tensile modulus of the analyzed nanocomposites.

Based on the aforementioned specificities, extensive studies were carried out with respect to the effects of different fibre fabrics multi-layering sequencing on the overall tensile and flexural properties of polymer based composites [4][5][6][7][8][9].

BACKGROUNDThe overall aim of the work is to provide comprehensive means of predicting and characterizing the properties of principal hybrid polymer based composite architectures that can simultaneously yield results of practical utility. This is accomplished by comparing, whenever possible, the theoretical predictions for the effective properties to available experimental data.The present work is divided into two parts. Part I deals with the author's scientific achievements that enabled to characterize quantitatively the main effective properties of self-developed hybrid polymer based composite architectures and different theoretical and computer-simulation methods used for comparison. Part II identifies future directions for scientific and research evolution and development.The introductory chapter in Chapter I was reserved to the state-of-the-art in the subject intended to be covered with the main body of the PhD thesis. This was done on purpose to illustrate the importance of developed subject that is under continuous evolution and that expanded after herein contributions. It is noteworthy that significant advances have been made recently in the quantitative characterization of hybrid composite materials of any type both theoretically and experimentally.The general objectives (Chapter II) were underlined and concise delivered to give the reader a preview of the concepts that will be discussed specifically in the subsequent chapters. Indirectly, they point toward one of the main aims of this work, namely to provide a direction for systematically analysis of hybrid polymer based composite materials.Chapter III was dedicated to the brief presentation of individual materials' selection, manufacturing issues, details on hybrid microstructures and finally, some practical information on experimental devices and settings considered. Practically, reproducibility issue of the experimental data processing can be potentially addressed through sharing these particular information results.Chapter IV provides several theoretical models used deploying a multi-step homogenization scheme to apply for individual combinations and effective property under consideration. These theoretical models were selected due to their ability to describe the 'details of the microstructures' (i.e. constitutive volume fractions, orientations, sizes, shapes, spatial distributions and surface areas of interfaces, etc.) and ability to encompass particular information that can be ascertained in practice.In the light of above, particular concerns were given to those structure/property relations that can be easily understood by apprentices, unaccustomed researchers on engineering field and finally, to materials' designers bounded by cost and time to perform measures on their mechanical applications for all possible combinations, phase properties and microstructures aimed to be developed.Chapter V extensively approaches the effective mechanical, dynamical, thermal stability and conductivity, fire retardant and electrical conductivity of particular hybr...
