Available in PDF, EPUB and Kindle. Book excerpt: Amphiphilic polymer co-networks (APCNs) are a type of polymeric hydrogel, their hydrophobic polymer segments and hydrophilic components produce less aqueous swelling, giving better mechanical properties than conventional hydrogels. This new class of polymers is attracting increasing attention, resulting in further basic research on the system, as well as new applications. This book focuses on new developments in the field of APCNs, and is organised in four sections: synthesis, properties, applications and modelling. Co-network architectures included in the book chapters are mainly those deriving from hydrophobic macro-cross-linkers, representing the classical approach; however, more modern designs are also presented. Properties of interest discussed include aqueous swelling, thermophysical and mechanical properties, self-assembly, electrical actuation, and protein adsorption. Applications described in the book chapters include the use of co-networks as soft contact lenses, scaffolds for drug delivery and tissue engineering, matrices for heterogeneous biocatalysis, and membranes of controllable permeability. Finally, an important theory chapter on the modelling of the self-assembly of APCNs is also included. The book is suitable for graduate students and researchers interested in hydrogels, polymer networks, polymer chemistry, block copolymers, self-assembly and nanomaterials, as well as their applications in contact lenses, drug delivery, tissue engineering, membranes and biocatalysis.

Download or read book PH Responsive Thin Film Membranes from Poly 2 vinylpyridine Water Vapor Induced Formation of a Microporous Structure written by and published by . This book was released on 2007 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: We report the fabrication of microporous thin film membranes with two-dimensionally arranged submicron pores whose size can be varied by changing pH of aqueous medium. A solution containing poly(2-vinylpyridine) partially quaternized with 1,4-dilodobutane (qP2VP) and unreacted 1,4-diodobutane (DIB) was used for the formation and deposition of the membranes on solid substrates. The membranes were spin-coated on to solid substrates in a controlled humid environment. The presence of water vapor in air was found to be a necessary condition for the pore formation. We studied the influence of relative humidity on the membrane morphology and proposed a mechanism of pore formation. Cross-linking the qP2VP membranes with DIB made them insoluble (stable) in organic solvents and acidic water. The cross-linked membranes demonstrated pH-dependent swelling, which had a strong influence on the pore size.

Download or read book Recent Drifts in PH Sensitive Reverse Osmosis written by Gehan Mohamed Ibrahim and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Preparation of some smart PAm-ZTS pH-responsive membranes, via reactions between ZTS and PAm under different conditions, was conducted for testing pressure-driven reverse osmosis membranes (PDROMs) in active rejection of Ce4+, Pr3+, Sm3+, Gd3+, Dy3+, and Ho3+ ionic lanthanide species in their 3+ and 4+ states. Recent theoretical models to designate the membrane operations were mathematically itemized, after selective characterization of the PDROMs. The pH scale response of the membrane was confirmed using static adsorption and hydraulic pervasion result estimations. The flux across the PAm-ZTS membrane decreased with the lowering pH value, with drastic decreases between pH 4 and 7, and was both reversible and durable with pH shifts between ~3 and ~8. At lower pH 3, the individual pores were in a closed-state due to the prolonged structure of the amide chains on the porous surfaces. In contrast, at pH 8, the higher pH value, the membrane pores were in an open-state format, because of the collapsed structures of the amide chains. This grants a clear possible approach for manufacturing some pH-responsive composite membranes and inspires further design for their stimuli-responsive actions by incorporating molecularly designed macromolecules, synthesized by controlled polymerization.

Download or read book The Delivery of Biologicals Across Endosomal Membranes by PH responsive Polymers written by Franziska Hausig-Punke and published by . This book was released on 2023* with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The efficient and safe delivery of complex biological agents offers great potential for the challenges of our time. Polymers offer considerable advantages in this regard, not only because of their low risk for immunogenic reactions, their comparatively inexpensive large-scale production and their long shelf life. The biological properties of organisms, organs, tissues and cells determine the design of safe and efficient delivery systems and should be considered as inspiration for new attempts to create effective materials. In addition to the balance between hydrophobicity and hydrophilicity, the degree of charge of a nanocarrier is also critical for efficient delivery and overcoming the endosome. Cationic charges do not only enhance cellular uptake but can also mediate a crossing of the endosomal barrier due to membrane interactions. The introduction of hydrophobic or even lipophilic components can further significantly increase membrane interactions. Besides the interaction with the cell membrane, it is important to consider that both the degree of charge and the hydrophobic-hydrophilic balance also affect the packaging and protection of sensitive biological cargo such as genetic material. However, cationic charges and hydrophobic components introduce some disadvantages, as electrostatic and hydrophobic interactions may disrupt the integrity of other cellular membranes, triggering toxic effects. Fine adjustment of the degree of charge and the hydrophobic-hydrophilic balance offer the possibility of balancing the requirements for a safe, yet efficient delivery process. In the present dissertation, various polymer systems with adjustable charge density and hydrophobic-hydrophilic balance were investigated with respect to their delivery efficiencies. A particular focus was set on the key step in delivery, the endosomal release.
