Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

open access: yesAdvanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Information erasure in copolymers [PDF]

open access: yesEPL (Europhysics Letters), 2013
Information erasure at the molecular scale during the depolymerization of copolymers is shown to require a minimum entropy production in accordance with Landauer's principle and as a consequence of the second law of thermodynamics. This general result is illustrated with an exactly solvable model of copolymerization, which also shows that the minimum ...

Wearable Haptic Feedback Interfaces for Augmenting Human Touch

open access: yesAdvanced Functional Materials, EarlyView.
The wearable haptic feedback interfaces enhance user experience in gaming, social media, biomedical instrumentation, and robotics by generating tactile sensations. This review discusses and categorizes current haptic feedback interfaces into force, thermal, and electrotactile stimulation‐based haptic feedback interfaces, elucidating their current ...

Origins of elastic properties in ordered nanocomposites [PDF]

open access: yes, 2004
We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system.

Harnessing Outer Space for Improved Electrocaloric Cooling

open access: yesAdvanced Functional Materials, EarlyView.
A novel radiative heat sink/source‐integrated electrocaloric (R‐iEC) system combines the electrocaloric (EC) effect with a thermally conductive radiative cooler (TCRC) to address heat dissipation limitations in EC devices. Utilizing outer space as a heat sink, the system achieves up to 240 W m−2 of heat dissipation performance, making it highly ...

Flexible Thermoelectric Generators Based on Single‐Walled Carbon Nanotube/Poly(aniline‐co‐acrylonitrile) Composites

open access: yesAdvanced Electronic Materials
Composites of polyaniline (PANI) with carbon nanotubes (CNTs) are widely studied for thermoelectric applications. In this work, acrylonitrile (AN) is incorporated into the backbone of aniline (ANI) to form a poly(ANI‐co‐AN) copolymer, which is in situ ...

Stability of parallel/perpendicular domain boundaries in lamellar block copolymers under oscillatory shear

open access: yes, 2006
We introduce a model constitutive law for the dissipative stress tensor of lamellar phases to account for low frequency and long wavelength flows. Given the uniaxial symmetry of these phases, we argue that the stress tensor must be the same as that of a ...
