2019 journal article

Self-Assembly of a Midblock-Sulfonated Pentablock Copolymer in Mixed Organic Solvents: A Combined SAXS and SANS Analysis

LANGMUIR, 35(4), 1032–1039.

By: K. Mineart*, J. Ryan n, M. Appavou *, B. Lee *, M. Gradzielski * & R. Spontak n 

TL;DR: These findings provide a potential pathway for the formation of solvent-templated films with more interconnected morphologies due to the greatly solvated micellar cores in solution, thereby enhancing the molecular, ion, and electron-transport properties of the resultant films.

2017 journal article

Adhesion and friction in polymer films on solid substrates: conformal sites analysis and corresponding surface measurements

Soft Matter, 13(19), 3492–3505.

By: R. An n, L. Huang *, K. Mineart n, Y. Dong*, R. Spontak n  & K. Gubbins n 

TL;DR: This analysis establishes that three dimensionless parameters play important roles in determining differences from bulk behavior for thin polymer films near to surfaces: a microscopic wetting parameter, αwx, defined as the ratio of polymer-substrate interaction to polymer-polymer interaction; a dimensionless film thickness; and dimensionless temperature.

Dual modes of self-assembly in superstrongly segregated bicomponent triblock copolymer melts

PHYSICAL REVIEW E, 91(1).

By: S. Woloszczuk *, K. Mineart n, R. Spontak n  & M. Banaszak *

TL;DR: On-lattice Monte Carlo simulations are employed to examine the phase behavior of molecularly asymmetric A(1)BA(2) copolymers possessing chemically identical endblocks differing significantly in length, establishing the coupled molecular-asymmetry and incompatibility conditions under which micelles form, as well as the temperature dependence of their aggregation number.
