Stratification in Drying Polymer–Polymer and Colloid–Polymer Mixtures
Langmuir, 2017Drying polymer-polymer and colloid-polymer mixtures were studied using Langevin dynamics computer simulations. Polymer-polymer mixtures vertically stratified into layers, with the shorter polymers enriched near the drying interface and the longer polymers pushed down toward the substrate.

Polymer-polymer interaction parameters in solvent/polymer/polymer ternary systems
European Polymer Journal, 1981Abstract Empirical equations defining the relationships between b23 and χ23 interaction parameters for the ternary systems toluene (1)/poly(dimethylsiloxane), PDMS, (2)/polystyrene, PS, (3) and benzene (1)/PDMS(2)/PS(3) have been determined. The dependences of both interaction parameters on the mean molecular weights of the macromolecular components ...

Self‐Healing Polymers Based on Coordination Bonds
Advances in Materials, 2019Self‐healing ability is an important survival feature in nature, with which living beings can spontaneously repair damage when wounded. Inspired by nature, people have designed and synthesized many self‐healing materials by encapsulating healing agents ...

Polymer-Polymer Phase Behavior
Science, 1991Different polymers can be combined into a single material in many ways, which can lead to a wide range of phase behaviors that directly influence the associated physical properties and ultimate applications. Four factors control polymer-polymer phase behavior: choice of monomers, molecular architecture, composition, and molecular size. Current theories

Introduction This chapter is concerned with the thermodynamic aspects of the fusion of binary mixtures of two homopolymers. The structural and morphological features that result from the departure from equilibrium, and their influence on properties, will be discussed in a subsequent chapter. Binary polymer blends present several different situations.

Chemical Reviews, 2001
Various aspects of supramolecular polymer were discussed. The hydrogen bonding enforced by liquid crystallinity and phase separation in the supramolecuar polymers were examined. The supramolecular polymers, based on discotic molecules, such as tryphenylenes, pthalocyanines and porphyrins were also elaborated.

ABSTRACT A variety of vinyl type polymers has been prepared and characterized to compare their viscosity behaviour with "established" technical polymers. Special emphasis is given to fundamental aspects of solution structure with regard to the conformation of a single chain and of chain to chain interaction.

Polymer structure and dynamics, and polymer-polymer interactions
Advances in Colloid and Interface Science, 1996Abstract Special architectures can be constructed from macromolecular building blocks by placing functional groups at well defined positions on the polymeric object. These functional groups can be linked together either by chemical reaction or by non-covalent bonds. Often, however, the position of the functional groups is not sufficiently well known,

The use of viscoelastic materials, such as polymers, constantly increases in the field of nanotechnology. These materials are softer than metallic and inorganic ones, and, because of that, they are easier to deform and wear off. The wear mechanisms occurring for viscoelastic materials are rather complex, and, generally, present more complications for a
