Unique and random wrinkle features are desired for applications, especially in anticounterfeiting. Multifunctional wrinkled materials as well as simple wrinkling methods are desired for more applications. In this study, free-standing wrinkle-patterne

Strong and tough hydrogels, important for several materials and bio-applications, typically consist of nanocomposites and double networks. There is the need to create hydrogels that exhibit tunable mechanical properties on demand without compromising

A fast (30 s) thermoresponse and rapid (30 min) self-healing were achieved by noncovalently incorporating a small fraction of poly(N-isopropylacrylamide) (PNIPAM) nanogels (≤0.18 wt %) into a benzyl methacrylate-co-octadecyl methacrylate-co-methacr

Self-healing hydrogels are attractive for a variety of applications including wound dressings and coatings. This paper describes the facile preparation and characterization of an autonomous self-healing hydrogel system comprising surfactant-free hydr

Solid polymeric films (plates) commonly exhibit only partial recovery after being subjected to a bending moment for some finite duration. This phenomenon, generally called bending recovery or core-set, has been described and successfully modeled in p

The effect of an added polyanion, sodium poly(styrene sulfonate) (NaPSS), on the thermoreversible gelation and remelting of gelatin gels has been investigated by polarimetry and rheology. The presence of NaPSS can either enhance or reduce collag- enl

We report oscillatory shear and steady‐shear measurements on a model main‐chain thermotropic polyether in its nematic and isotropic phases, and in the nematic–isotropic biphase. The nematic phase is viscoelastic on all time scales measured. Sin

We report the viscosity and the modulus of near-critical polyester gels. Previous work has shown that these gels lie in the middle of the static crossover between mean-field and critical percolation. Above the gel point, the modulus data are well des

Tracer diffusion of the semiflexible main-chain liquid crystalline polyether [OPhC(CH 3 )=CHPhO(CH 2 ) 7 ] 0.5 [OPhC(CH 3 )=CCPhO(CH 2 ) 9 ] 05 was studied using forward recoil spectrometry. Investigation of the temperature dependence of melt diffusi

Small amplitude oscillatory shear has been used to study thermotropic liquid-crystalline polymers that have mesogenic groups pendant to flexible backbones. The polymers studied form nematic and smectic glasses, enabling viscoelastic response to be st
