Titanium (Ti) is the most commonly used material for cranial prostheses. However, this does not exhibit same mechanical properties as bone. Incorporating polymers onto Ti by combining both their a solution to overcome issue. Thus, sandwich materials made of two skin sheets and poly(methyl methacrylate) (PMMA) core are promising structures design biomedical The “grafting to” from” procedures fun...

Ricinoloxazoline maleinate (OXA) was grafted by melt free radical grafting onto polyolefins and elastomers to produce new compatibilizers for polymer blends. Effects of initial monomer and peroxide concentrations on the degree of grafting, on the amount of residual monomer, and on the side reactions were investigated. Reactive compatibilizers could be prepared with a suitable choice of processi...

We investigate the effect of mobile polymer brushes on proteins embedded in biological membranes by employing both Asakura-Oosawa type theoretical model and coarse-grained molecular dynamics simulations. The brush polymer-induced depletion attraction between changes non-monotonically with size brush. interaction, which is determined ratio protein to grafting distance polymers, increases linearl...

In this work, three surface functionalization processes have been studied: the spontaneous grafting fromdiazonium salts, the chemically induced grafting from diazonium salts and the chemically induced graftingfrom diazonium salts in presence of vinylic monomers (which is Graftfast). These processes work at roomtemperature, atmospheric pressure, in aqueous medium and without any ext...

Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically.  ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...

Film forming, stable hybrid latexes made of methyl metacrylate (MMA), butyl acrylate (BA) and 2-hydroxyethyl methacrylate (HEMA) copolymer reinforced with modified multiwalled carbon nanotubes (MWCNTs) were synthesized by in situ miniemulsion polymerization. The MWCNTs were pretreated by an air sonication process and stabilized by polyvinylpyrrolidone. The presence of the MWCNTs had no signific...

Polyurethane (PU) homopolymers and PU/polystyrene (PS) interpenetrating polymer networks (IPNs) were successfully synthesized changing the length of the pendant poly(ethylene oxide) (PEO) chains and the grafting density of PEO chains. All the PU/PS IPNs had the microphase-separated structures in which the PS-rich phase domains were dispersed in the matrix of the PU-rich phase. The domain size d...

Over the last decade versatile, electrostatic layer-by-layer (LbL) assembly methods involving polyelectrolytes have been widely used in the preparation of hollow capsules. These capsules can be fabricated by the stepwise adsorption of polyelectrolytes with charges that are opposite from their aqueous media onto templating cores, especially organic or inorganic particles and biopolymers, followe...

Pseudo-materials are effective in boosting the specific capacitance of supercapacitors, but during service their degradation may also be very strong, causing reduced cycling stability. Here, we show that a carbon nanotube sponge grafted by two conventional pseudo-polymer layers in sequence can serve as a porous supercapacitor electrode with significantly enhanced cycling stability compared with...

Reactive extrusion is an attractive green route for cost-effective polymer processing, which has the potential to enhance the commercial viability of biomass-derived materials. In reactive extrusion, compatibilizers can be generated in the blend preparation through polymer-polymer grafting reactions using functionalized polymers. One very interesting new green strategy for processing is the use...
