Thermoplastic polysiloxane-based polyurethane (Si-TPU) has been attracting a great deal of attention because the dual advantages polysiloxane and polyurethane. However, strength Si-TPU with traditional structure is low, improvement urgently needed for diverse applications. Herein, we design soft segment (SS) two urethane groups at end chain, then prepare series Si-TPUs through designed SS, isophorone diisocyanate 1,4-butanediol. Such structural improves polarity SS endows more regular...
Elastomers inevitably suffer scratches and damage during the application; thus, design fabrication of self-healing elastomers with covalent adaptive networks is a meaningful strategy to extend service life materials. In this study, facile two-step approach was proposed synthesize based on dynamic oxime–carbamate bonds. Hydroxyl-terminated polybutadiene first reacted isophorone diisocyanate prepolymer isocyanate groups terminated, followed by further reaction dimethylglyoxime as chain...
Elastomers with distinctive viscoelastic behavior are widely utilized in vibration and noise reduction. However, most elastomers derived from petroleum-based sources their functionality limited to a single purpose. In this work, biobased polyurethane (bio-PU) elastomer was synthesized poly(trimethylene ether) glycol, then H-bond cross-linking strategy implemented by incorporating tannic acid (bio-TA) fabricate PU/TA (bio-PU/TA) damping composites. The structures performances of the...
Molecular dynamics (MD) simulations are used to investigate the fundamental damping mechanism of AO-60/nitrile-butadiene rubber (AO-60/NBR) composites at molecular level in this study. The hydrogen bonds (H-bonds), binding energy, and fractional free volume (FFV) AO-60/NBR were obtained. composite with an AO-60 content 36 phr had largest H-bonds, highest smallest FFV, all indicating a good compatibility between NBR performance composite. experimental FTIR, 1H-NMR results also showed that two...
Polylactic acid (PLA) has received increased attention in the development of shape-memory polymers and biomedical materials owing to its excellent physical properties good biocompatibility biodegradability. However, inherent brittleness high shape-recovery temperature this material limit application human body. Herein, we fabricated a PLA-based thermoplastic polyurethane (PLA-TPU) prepared from modified PLA-diol, dicyclohexylmethane-4,4′-diisocyanate, 1,4-butanediol solve limitations pure...
Abstract Flexible wearables have attracted extensive interests for personal human motion sensing, intelligent disease diagnosis, and multifunctional electronic skins. However, the reported flexible sensors, mostly exhibited narrow detection range, low sensitivity, limited degradability to aggravate environmental pollution from vast wastes, poor antibacterial performance hardly improve skin discomfort inflammation bacterial growth under long‐term wearing. Herein, bioinspired featuring highly...
Rubber tires are fundamental components of modern society and industrial operations, holding an irreplaceable position in the global manufacturing transportation sectors. The potential for traditional rubber to enhance performance is gradually approaching its limits, rendering it challenging further improve low rolling resistance, high wet-skid wear resistance (called “magic triangle”). Moreover, reliance on petroleum resources hinders sustainable development tires. In this work, a series...
Thermoplastic polyurethanes (TPUs) have received considerable attention because of their flexible structure and comprehensive performance. 3,3-Dimethyl-4,4′-diphenyl diisocyanate (TODI) was first introduced to fabricate high-performance TPU by tailoring the mole ratio hard segment soft molecular weight for three-dimensional (3D) printing. The influence microstructure on glass transition temperature, tensile strength, modulus, loss factor, softening temperature investigated. annealing process...
Rubber composites make an important contribution to eliminating vibration and noise owing their unique viscoelasticity. However, it is find alternative bio-based products with high damping properties the shortage of petrochemical resources poor performance. The ability self-heal additional characteristic that highly desirable because can further increase service life safety such products. In this study, a polylactic acid thermoplastic polyurethane (PLA-TPU) its (PLA-TPU/AO-80) are...
Additive manufacturing via fused deposition modeling (FDM) has become one of the most widely used technologies owing to its ease operation and effective cost. However, disappointing interlayer adhesion produced by FDM often results in inferior mechanical properties, which a technical bottleneck for industrial production. Herein, we demonstrate facile efficient printing strategy enhance introducing self-healing mechanism into material, thereby concurrently enhancing properties isotropy...
The operation of mechanical equipment inevitably generates vibrations and noise, which are harmful to not only the human body but also in use. Damping materials, can convert energy into thermal energy, possess excellent damping properties glass transition region alleviate problems caused by vibration noise. However, these materials mainly rely on petroleum-based resources, their temperatures (Tg) lower than room temperature. Therefore, bio-based with high at temperature must be designed for...
