Abstract
Eucommia ulmoides gum (EUG) is composed of trans-1,4-polyisoprene with high flexibility and crystallinity, and could be utilized as elastic and thermoplastic materials. Taking advantage of the unique crystallization characteristics, a series of EUG-based complex elastic fibers were prepared by wet-spinning method using different types of needles. It was found that the EUG fiber displayed excellent mechanical properties including high tensile strength (42.8 MPa), elongation at break (572%), and toughness (136.8 MJ m−3). The complex elastic fibers combining different compositions and various architectures have higher temperature sensitivity and excellent shape memory recovery ability compared to EUG elastomer. Meanwhile, the elastic fibers containing EUG and butyl rubber (IIR) exhibited better damping properties than pristine EUG. Therefore, this work provided a way to enhance the functionality and expand the application of bio-based EUG materials.
期刊介绍:
Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers.
Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
