Grzetic D, Delaney K, Fredrickson G
ACS Macro Lett . 2022 May; 8(8):962-967. PMID: 35619489
We study a salt-doped polarizable symmetric diblock copolymer using a recently developed field theory that self-consistently embeds dielectric response, ion solvation energies, and van der Waals (vdW) attractions via the...

Danielsen S, Davidson E, Fredrickson G, Segalman R
ACS Macro Lett . 2022 May; 8(9):1147-1152. PMID: 35619444
The delocalization of electrons in conjugated polymers impacts their chain shape, affecting their local ordering, self-assembly, and ultimately charge transport. Conjugated polyelectrolytes introduce electrostatic interactions as a molecular design parameter...

Danielsen S, Nguyen T, Fredrickson G, Segalman R
ACS Macro Lett . 2022 May; 8(1):88-94. PMID: 35619414
Electrostatic assembly of conjugated polyelectrolytes, which combine a π-conjugated polymer backbone with pendant ionic groups, offer an opportunity for tuning materials properties and a new route for formulating concentrated inks...

Garcia J, Iwama T, Chan E, Tree D, Delaney K, Fredrickson G
ACS Macro Lett . 2022 May; 9(11):1617-1624. PMID: 35617063
We report the first simulations of nonsolvent-induced phase separation (NIPS) that predict membrane microstructures with graded asymmetric pore size distribution. In NIPS, a polymer solution film is immersed in a...

Shi W, Tateishi Y, Li W, Hawker C, Fredrickson G, Kramer E
ACS Macro Lett . 2022 May; 4(11):1287-1292. PMID: 35614830
We demonstrate that small domain features (∼13 nm) can be obtained in a series of polystyrene (PS) and poly(lactic acid) (PLA) block copolymers, PS-(PLA) and (PS)-(PLA), that combine miktoarm molecular...

Luo Y, Montarnal D, Treat N, Hustad P, Christianson M, Kramer E, et al.
ACS Macro Lett . 2022 May; 4(12):1332-1336. PMID: 35614778
In addition to the traditional parameters of chi (χ) and degree of polymerization (), we demonstrate that the segregation strength of a diblock copolymer can be increased by introduction of...

Paradiso S, Delaney K, Fredrickson G
ACS Macro Lett . 2022 May; 5(8):972-976. PMID: 35607214
Multiblock polymers (MBPs) show great promise as a platform for synthesizing materials with highly customized nanostructures. In these systems, the subtle balance of chain configurational entropy and interactions between dissimilar...

Sherck N, Shen K, Nguyen M, Yoo B, Kohler S, Speros J, et al.
ACS Macro Lett . 2022 May; 10(5):576-583. PMID: 35570772
Polymer formulations possessing mesostructures or phase coexistence are challenging to simulate using atomistic particle-explicit approaches due to the disparate time and length scales, while the predictive capability of field-based simulations...

Fredrickson G, Delaney K
Proc Natl Acad Sci U S A . 2022 Apr; 119(18):e2201804119. PMID: 35471906
Free energy evaluation in molecular simulations of both classical and quantum systems is computationally intensive and requires sophisticated algorithms. This is because free energy depends on the volume of accessible...

Sengupta R, Tikekar M, Delaney K, Villet M, Fredrickson G
Soft Matter . 2022 Mar; 18(15):2936-2950. PMID: 35348172
Reactive blending of immiscible polymers is an important process for synthesizing polymer blends with superior properties. We use a phase-field model to understand reaction dynamics and morphology evolution by diffusive...
