Polyelectrolyte brushes have drawn increasing attention because their physicochemical properties can be modulated by adjustment of the pH and ion concentration. Here, we report controlled grafting poly acrylic acid containing cysteine side chains onto supported lipid membranes to allow for modulation viscoelasticity as well interfacial potential ion-specific interactions, that is, with cadmium ...

The polymer of intrinsic microporosity PIM-1 was synthesized with different topologies and negligible network content. A more rapid heating rate from room temperature yielded a predominantly di-substituted (D-PIM-1), whereas marginally lower produced branched structure (B-PIM-1). Both polymers were acid-hydrolyzed to give carboxylic acid functionalization (cPIM-1), as indicated by FT-IR, 1H NMR...

in production of tissue paper, the adhesion of a liquid adhesive creping aid, compound polymer, as creping aids on the yankee dryer surface was investigated. a compound polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin (pae) as an adhesive agent, polyvinyl alcohol (pva) as a modifier agent, and cationic fatty acid (cfa) and ethylene glycol (eg) as release age...

crosslinked poly(acrylic acid)s were prepared using two types of crosslinker by precipitation polymerization method in a binary organic solvent. n,n’-methylenebisacrylamide (mba) and polyethylene glycol dimethacrylate (pegdma-330) were used as low-molecular weight and long-chain crosslinkers, respectively. the effect of various types of crosslinkers on polymer characteristics (i.e., gel content...

We demonstrate how the Laplace operator can be combined with a stochastic jump process to describe the evolution of a polymer network. Growth processes in polymer networks can proceed through the transfer of rather large oligomeric subunits from a pool of soluble molecules into the laments forming the network. In such a situation stochastic jump processes are a natural tool for the description ...

A method is developed to construct and analyse a wide class of graphs embedded in Euclidean 3D space, including multiply-connected and entangled examples. The graphs are derived via embeddings of infinite families of trees (forests) in the hyperbolic plane, and subsequent folding into triply periodic minimal surfaces, including the P,D, gyroid and H surfaces. Some of these graphs are natural ge...

Although buckling instabilities in elastic solids have been known for a long time, high interest in this phenomenon is relatively recent. The current and prospective applications in flexible electronics, materials with tunable surface properties (adhesion and wettability), responsive photonic and phononic structures, and reinforced nanocomposites led to a surge in the interest in buckling insta...

The complex damped orientational diffusion model of polymer local, main chain motion in moderately dilute solution is extended to include the effects of attached probes and periodic side chains on the dynamics. In the case of an appended probe attached to the main chain, a prescription is given for extracting the contribution of the probe to the local, main chain dynamics and thereby allows one...

The finitely extensible nonlinear elastic (FENE) dumbbell model consists of the incompressible Navier–Stokes equation for the solvent and the Fokker–Planck equation for the polymer distribution. In such a model, the polymer elongation cannot exceed a limit m0 which yields all interesting features of solutions near this limit. This work is concerned with the sharpness of boundary conditions in t...
