Target morphologies via a two-step dissolution-quench process in polymer blends.

نویسنده

  • Nigel Clarke
چکیده

A novel process for obtaining controlled morphologies in polymer blends is modeled numerically. Particles of one type of polymer are allowed to dissolve in a matrix of a dissimilar polymer. Prior to complete dissolution the blend is quenched into the two-phase region, such that phase separation takes place. The combination of the incomplete dissolution and the wavelength selection process associated with phase separation results in particles that during the "intermediate" stages have a core that is significantly richer in the matrix material.

The influence of branching efficiency on the rheology and morphology of melt state long chain branched polypropylene/polybutene-1 blends

In this study, the compatibility of the blends of polypropylene (PP) and polybutene-1(PB-1) homopolymer before and after long chain branching process were studied. The blends were prepared and long-chain branched directly via reactive extrusion process in presence of free radical initiator and trimethylolpropane tri methacrylate (TMPTMA) poly functional monomer. The optimum percentage of TMPTMA...

Numerical Studies of Phase Separation in Models of Binary Alloys and Polymer Blends

We review some recent results concerning numerical studies of the CahnHilliard equation in three dimensions to describe the phase separation process in a mixture after a quench within the coexistence curve. We focus on the late time behavior for two experimentally relevant systems: binary alloys and binary polymer blends. We find that, in both systems, dynamical scaling with a time dependent ch...

Various crystalline morphology of poly(butylene succinate-co-butylene adipate) in its miscible blends with poly(vinylidene fluoride).

Poly(vinylidene fluoride) (PVDF) and poly(butylene succinate-co-butylene adipate) (PBSA) are crystalline/crystalline polymer blends with PVDF being the high-T(m) component and PBSA being the low-T(m) component, respectively. PVDF/PBSA blends are miscible as shown by the decrease of crystallization peak temperature and melting point temperature of each component with increasing the other compone...

NONLINEAR KINETICS OF SPINODAL DECOMPOSITION, AND DISSOLUTION OF INHOMOGENElTIES FORMED BY SPINODAL DECOMPOSITION IN POLYMER BLENDS

Nonlinear kinetics of both spinodal decomposition at early stages, and the dissolution of homogeneities formed during spinodal decomposition,is studied. Variation of the scattering intensity during a complete cycle consisting of a step temperature change from T i in the one-phase. region to T2 in the two-phase region, a period of spinodal decomposition followed by a temperature drop from T2 bac...

Similarity of the signatures of the initial stages of phase separation in metastable and unstable polymer blends.

Time-resolved small angle neutron scattering was used to probe the initial stages of liquid-liquid phase separation in both critical and off-critical binary polymer blends, and the critical (q(c)) and most probable (q(m)) wave vectors were identified for several quench depths. For the critical blend, the Cahn-Hilliard-Cook theory provides a framework for analyzing the data and explains the obse...
