Green renewable resource has become a global hot spot. In this study, naturally occurring resource rosin derivative (RAG) was used to prepared a cationic waterborne polyurethane (WPU) dispersion using...
Chain extender is a major additive in polyurethane adhesive preparation, which has a great influence on its molecular weight, green strength, and thermal resistance. In this work, we first synthesized...
Synthesis of vitrimer with dynamic?covalent bond?is a surprising solution to overcome the inherent limitations of traditional?thermosets. A bio-based vitrimer-like?polyurethane?formed by?castor oil,?v...
Environmentally friendly flame retardant such as polysiloxane has long been sought for varied studies in recent years and can be further improved to overcome the challenges of additional applications....
Environmentally friendly and lightweight silylated cellulose nanocrystal (SCNCs)/waterborne polyurethane (WPU) composite films that exhibit excellent mechanical properties and water resistance were pr...
Fossil fuel resources depletion and growing concern about environmental issues have raised the demand for newly sustainable biomaterials. To address this challenge, a new type of biodegradable and env...
A stretchable magnetorheological material (SMRM) consisting of micro-meter carbonyl iron (CI) particles, low cross-linking polyurethane (PU) polymer and porous PU sponge has been developed. Due to the...
A new kind of polyurethane (PU) magnetorheological (MR) foam was prepared via in situ polymerization and foaming for the first time. A chain-like structure of carbonyl iron particles in the liquid pol...
This work focused on the mechanical behavior, especially creep resistance, of thermoplastic polyurethane (TPU) filled with ozone-treated multi-walled carbon nanotubes (MWCNTs). It was found that the o...
The highly filled anisotropic polyurethane (PU) magnetorheological elastomers (MREs) were prepared through an in-situ one-step polycondensation process under a magnetic field. The carbonyl iron formed...
Highly filled polytetramethylene ether glycol (PTMEG)-based polyurethane (PU) magnetorheological elastomers (MREs) with anisotropic structure and good mechanical properties were prepared. The difficul...
Magnetorheological gels (MRGs) known as a new kind of magnetorheological material are composite gels containing magnetic particles suspended in polymer gels. In this study, a category of MR polymer ge...
Magnetorheological elastomers (MREs) are mainly composed of magnetizable particles and elastic polymer. The polymer matrix plays an important role in mechanical performances of MREs. In this study, th...
A series of cross-linked polyether-polyester polyurethane dispersions modified with organosiloxane were prepared based on hydroxyl-terminated polydimethylsiloxane (HTPS) as hydrophobic component and 3...
The highly filled isotropic polyurethane (PU) elastomer with a magnetorheological (MR) effect was prepared through an in situ polycondensation method. The carbonyl iron particles were treated by coupl...
