Synthesis and Application of Well-Defined Stimuli Responsive Materials
… which provided interesting surface structured materials without the need for development or post curing. The same material was used to prepare isotropic colloidal particles of the polymer. These latex particles were transformed to ellipsoids in response to irradiation by linearly polarized …

Design and development of stimuli-responsive materials: pH sensitive polymersomes and poly(olefin sulfone)s
Stimuli-responsive materials are materials exhibit a response when exposed to specific external triggers. These materials are powerful tools for material development in areas such as encapsulation, photoresists, sensors, self-healing materials, drug delivery, and transient electronic devices. A …

Thermo-responsive and electroconductive shape-memory polymer composites for useful applications
Shape-memory polymers (SMPs) are stimuli-responsive materials with the ability to undergo a large recoverable deformation upon the application of an external stimulus. International research interest into the shape-memory effects (SMEs) of these polymers is rapidly growing. Unique polymer …

Simulation of Weak Polyelectrolyte Brushes
Using molecular simulations, the stimuli-responsive behavior of weak polyelectrolyte brushes (PEBs) and weak polyampholyte brushes (PABs) was examined with respect to pH, salt concentration, monomer sequence and grafting density. While PEBs have only acidic or basic monomers, PABs contain both …

High performance materials for artificial muscles and energy storage devices
Artificial muscles (i.e., stimuli-responsive materials) are muscle-like materials and devices that mimic muscle's functionality (e.g., contraction, rotation, and bending) in different aspects. Some of the common performance metrics used for evaluating artificial muscles are cycle life, …

Synthesis and characterisation of new tetrathiafulvalene-oligofluorene derivatives for moisture indicators
The term 'smart materials' refers to a category of materials that are able to dynamically respond to external stimuli through a change in physical and/or chemical properties. The versatility afforded by organic materials makes them attractive candidates in the development of new sensing materials. …

Asymptotically nonliner oscillatory shear: theory, modeling, measurements and applications of nonlinear elasticity to stimuli-responsive composites
Viscoelastic materials, such as crosslinked networks of synthetic and biological polymers, exhibit a nonlinear rheological response to mechanical deformation. Oscillatory shear is a popular deformation protocol for viscoelastic characterization, both linear and nonlinear, the latter referred to as …

Structure and Morphology of Photoreactive Monomer–Nanoparticle Mixtures Under Patterned Irradiation
… processing–structure relationships is central to materials science. In this work, we seek answers to whether morphology can be controlled during Light–Induced Self–Writing (LISW) in polymer composite materials, and if yes, how? LISW is based on the ability of light to undergo divergence–free …

Dibenzo-30-crown-10: Synthetic optimization and studies of the binding conformation
… agents, sensors, molecular machines, and stimuli responsive materials "smart polymers". Despite the vigorous research activity in the field, DB30C10 has received surprisingly little attention. DB30C10 was reported in 1967 and has been commercially available since 1992; however, it has been …

Bridging Mesoscale Phenomena and Macroscopic Properties in Block Copolymers Containing Ionic Interactions and Hydrogen Bonding
… and inter-molecular interactions to achieve stimuli-responsive materials in various applications, such as artificial muscles, thermoplastic elastomers, and reversible biomacromolecule binding. The relationship between non-covalent interaction promoted mesoscale phenomenon (such as morphology) …

Particles at fluid interfaces : behaviour and derived materials
… behaviour at fluid interfaces using novel and stimuli responsive particles, and how their adsorption at these interfaces affect the emulsions, foams or other materials that they are stabilising. Materials stabilised solely by particles are of great interest due to long-term stability, generally …

Conjugated Polymer Brushes (Poly(3-hexylthiophene) brushes): new electro- and photo-active molecular architectures
… head-to-tail poly-3-alkylthiophenes – benchmark materials for organic electronics - can be now selectively grafted from appropriately-terminated surfaces to produce polymer brushes of otherwise soluble polymers - the architecture earlier accessible only in the case of non-conductive polymers. In …

Chemomechanics of self-oscillating gels
Biological materials such as cardiac and skin tissue exhibit the unique capacity to transduce mechanical stimuli into propagating electrical and chemical signals throughout the body. Few synthetic materials have been engineered to produce communicative chemical signals in response to mechanical …

The Design, Preparation and Characterisation of Light-Responsive Pickering Emulsions
Light-responsive particle-stabilised (Pickering) emulsions can, in principle, be selectively emulsified or demulsified on-demand through the remote application of light. However, despite their wide-ranging potential in applications such as drug delivery and biphasic catalysis, their rational design …
