Bimodal condensation silicone elastomers as dielectric elastomers

open access: yes, 2016
Lately, dielectric elastomers (DEs) which consist of an elastomer sandwiched between electrodes on both sides, have gained interest as materials for actuators, generators, and sensors. An ideal elastomer for DE uses is characterized by high extensibility, flexibility and good mechanical fatigue as well as high electrical and mechanical breakdown ...

A Super‐Adhesive Air Filter With Capillarity‐Mediated Spontaneous Particle Absorption via Dynamic Bond Exchange

open access: yesAdvanced Materials, EarlyView.
We address the inherently weak particle adhesion of conventional air filters by coating a dynamically crosslinked adhesive layer that delivers capillarity‐driven strong adhesion and particle absorption mediated by dynamic bond exchange. The resulting enhancement in particle adhesion enables efficient ultrafast (up to 20 m s−1) and omnidirectional ...

Development of a cell population migration assay [PDF]

open access: yes, 2009
Cellular migration is central to many physiological and pathological processes, from wound healing and the immune response to cancer cell invasion. Many in-vitro assays have been developed to study these processes and can be classified by the nature of ...

Self-healing silicone elastomers

open access: yes, 2022
As the field of soft robotics has matured, the development of sustainable dielectric elastomer actuators (DEAs) has become all the more relevant. This can be accomplished by both extending the lifetime of DEAs and establishing end-of-life perspectives for the actuators. The aim of this thesis was thus to develop a new soft thermoplastic elastomer (TPE)

Liquids as Reinforcements for Anisotropic and Tough Soft Matter Composites

open access: yesAdvanced Materials, EarlyView.
Liquid metal droplets are shaped and oriented within soft elastomers to create all‐soft matter composites with programmable mechanical anisotropy. These liquid inclusions act as fiber‐like reinforcements, enabling directional stiffness, enhanced toughness, and controlled crack steering under extreme deformation, offering new routes to resilient soft ...

Conductive Hydrogels for Exogenous Sensing and Cell Fate Control

open access: yesAdvanced Materials, EarlyView.
We engineer electrically conductive hydrogels by combining sulfated glycosaminoglycans with semiconducting polymers. These hydrogels bind bioactive proteins, including growth factors, whose release or retention can be modulated by low‐voltage stimulation. The hydrogels are also integrated as 3D channels in organic electrochemical transistors as part of

Ultra-high Elongation Silicone Elastomers

open access: yes, 2016
Silicone elastomers with elongations approaching 5000% are now available. These elongations are nearly 4 times greater than any commercial elastomer. The new elastomers utilize a cure mechanism which generates elastomeric properties by driving linear polymers to extremely high molecular weights with concomitant formation of intra-chain and inter-chain ...
