Preparation and Performance of Self-healing Polyurethane with Reversible Dual Cross-linked Networks
Pige Kexue Yu GongchengA series of double-crosslinked polyurethane elastomers were prepared by physically crosslinking a single-crosslinked network of reversible disulfide-bonded polymers and a single-crosslinked network of reversible Fe3+-coordination-bonded polymers. Through

Electro-expulsive separation system [PDF]
, 1987 An electro-expulsive system has one or more overlapped conductors, each comprising a flexible ribbon conductor, which is folded back on itself. The conductors are embedded in an elastomeric material.

Control of elasticity in cast elastomeric shock/vibration isolators [PDF]
, 1974 Elasticity is determined by isolators physical dimensions and by type of elastomer used. Once elastomer is selected and cast between two concentric tubes of device, isolator elasticity will remain fixed.

Elasticity of Polydomain Liquid Crystal Elastomers
, 2011 We model polydomain liquid-crystal elastomers by extending the neo-classical soft and semi-soft free energies used successfully to describe monodomain samples. We show that there is a significant difference between polydomains cross-linked in homogeneous

Phase chirality and stereo-selective swelling of cholesteric elastomers [PDF]
, 2003 Cholesteric elastomers possess a macroscopic ``phase chirality'' as the director n rotates in a helical fashion along an optical axis $z$ and can be described by a chiral order parameter.

Extraction process and characterization of Taraxacum kok-saghyz (TKS) latex
HeliyonTaraxacum kok-saghyz (TKS) latex is a natural latex produced from its root, and its extraction optimization process is mainly studied in the present paper. The composition of fresh roots of TKS was quantitatively analyzed, and the results showed that the
