Abstract: This work presents the synthesis of polyacrylamide-gelatin (PAM-G) semi-interpenetrating hydrogels, as well as the study of the swelling capacity of this material at different pH's, and we report its Young modulus. The hydrogels were crosslinked with N,N-methylenebisacrylamide and synthesized at different acrylamide/gelatin weight relationship. It was observed that the swelling capacity of the hydrogels increases when the gelatin concentration is increased; while the Young modulus (at the swelling equilibrium) decreases lightly. Therefore, the gelatin has a small effect in the Young modulus, unlike its influence in the swelling ability. The swelling experiments reveal that the PAM-G hydrogels increase its swelling capacity in alkaline mediums because the presence of the hydrophobic functional groups (mainly COO-) in the gelatin structure.

A comparison of the polymerization kinetics of nanoemulsions prepared by Phase Inversion Temperature (low energy method) and microfluidization (high energy method), as well as polymer characteristics are presented. Nanoemulsion polymerizations carried out a 20°C were extremely fast using a par redox especially for the low-energy nanoemulsions. The particles obtained were only slightly larger than the original nanoemulsion droplets, indicating that the droplets acted as templates, and that squalane diminished substantially monomer diffusion between reacting and non-reacting monomer droplets. Molar masses and glass transition temperatures of the poly(hexyl methacrylate) obtained here were practically independent of conversion and surfactant concentration, as well as of the nanoemulsification method used. © 2013 Copyright Taylor and Francis Group, LLC.",,,,,,"10.1080/10601325.2013.802147",,,,"http://www.scopus.com/inward/record.url?eid=2-s2.0-84879638938&partnerID=40&md5=64726cca6af3f86c174b8c0402ae63d2

These binary mixtures were either partially or completely miscible within the composition range studied and were characterized by differential scanning calorimetry (DSC) and Fourier transformed infrared spectroscopy (FTIR). Carbon nanotubes (CNTs) were prepared by a thermal treatment of polyester synthesized through the chemical reaction between ethylene glycol and citric acid over an alumina boat. High resolution transmission electron microscopy (HRTEM) was used to characterize the synthesized CNTs. Films of composite materials containing CNTs were obtained after evaporation of the solvent used to prepare solutions of the four types of binary polymer blends. Young's moduli of the composites were obtained by thermomechanical analysis at room temperature. Only one glass transition temperature was detected for several compositions on both binary blends and the composite material matrices. Evidence of hydrogen bond formation was recorded for both miscible blends and composite materials. The degree of crystallinity and Young's moduli of the CNT-polymer composites increased compared to the single polymer blends. " 2008 Wiley Periodicals, Inc.
