Morphology re-entry is reported in a series of PS-b-PI-b-PS' asymmetric triblock copolymer and PS homopolymer (hPS) blends, where PS and PS' are polystyrenes of different lengths and PI is poly(isoprene). For example, with increasing the hPS content, a morphology sequence from lamellae to PS hexagonal cylinders and back to lamellae could be clearly identified, where PS hexagonal cylinders re-enters the phase diagram unexpectedly. However, this morphology re-entry is absent in the theoretical SCFT phase diagram.
- Coatings with thermally switchable surface energy produced from poly(ethylene oxide)-poly(dimethylsiloxane) block copolymer films

Amphiphilic poly(ethylene oxide)-poly(dimethylsiloxane), PEO-PDMS, block copolymers are synthesized and employed as thermally switchable (hydrophilic vs. hydrophobic) coatings. Above the order-disorder transition temperature (TODT) the polymer chains form a disordered melt. Upon cooling through TODT in dry or wet air, either the hydrophobic (PDMS) or hydrophilic (PEO) block, respectively, presents at the surface. The effect is fully reversible; reheating above TODT erases the wetting behavior, which is again set by cooling in the appropriate environment.
- Transient bioelectronics: Electronic properties of silver microparticle-based circuits on polymeric substrates subjected to mechanical load

Transient soft bioelectronics are fabricated and characterized for their electronic attributes when subjected to external mechanical force. Effects of magnitude and frequency of strain on electrical properties of stretchable bioelectronics are studied and reported. Also, transiency behavior of bioelectronics is characterized and analyzed as a function of the degradation attributes of substrates.
- Viscoelastic properties of ultrathin polycarbonate films by liquid dewetting
Jinhua Wang and Gregory B. McKenna
Article first published online: 27 AUG 2015 | DOI: 10.1002/polb.23807
In this work, the change in the glass transition temperature (Tg) as a function of film thickness for polycarbonate is investigated using a liquid dewetting technique and compared with literature reports for different methods. An obvious Tg reduction with decreasing film thickness was observed. The degree of Tg reduction is similar to results from the literature for PC films supported on rigid substrates.
- Thermal stimuli-responsive behavior of pyrene end-functionalized PDMS through tunable Π–Π interactions

Article first published online: 21 AUG 2015 | DOI: 10.1002/polb.23805
Stimuli-responsive pyrene end-functionalized poly(dimethyl siloxane) forms pyrene nanocrystals by strong π–π interactions between the polymer ends. The thermal and rheological behavior during various applied thermal stimuli was investigated. Their thermo-responsiveness was significantly affected by polymer molecular weight which influences pyrene end density. The tunability of their properties by the addition of various additives, including graphene oxide, was explored.
