“…Because the SSs of polyester‐based PU also contained many CO groups, the shift of hydrogen bonds shall be attributed to the more favorable hydrogen bond formation between hard domains (HDs) and TiO 2 nanoparticles. TiO 2 could interact with both HSs and SSs to influence microphase separation; the distribution of these particles in HSs or SSs might be related to the polarity of filler 10,13,14,19,55 …”

The microphase separation behavior of polyurethane (PU) strongly affects its mechanical, thermal, electrical, and other functional properties. Adding fillers to change the degree of microphase separation (DPS) in PU is a convenient and efficient method. Although many scholars have tried to regulate the microphase separation of PU by adding fillers, there are still many controversies about the effect. In this review, we classify commonly used fillers into three categories according to their morphology: spherical fillers, fibrous fillers, and layered fillers, and summarize their effects on the microphase separation behavior of PU. We explore the similarities and differences in the mechanisms by which different fillers affect the microphase separation of PU, and find that the polarity, morphology, size of fillers, and preparation method have a significant impact on the degree of microphase separation in PU. The impact of microphase separation on the mechanical properties of PU has also been summarized to illustrate their close relationship. We hope that these summaries will provide some guidance for the development of new high‐strength and multifunctional PU composites.Highlights Summarized recent research progress on effect of common fillers on DPS of PU. Common fillers are classified into three categories based on their morphology. Common laws of the fillers impact on the DPS are classified and discussed. The close relationship between DPS and mechanical properties is reviewed. Provided information for high‐strength and multifunctional PU development.

Elastomers with distinctive viscoelastic behavior are widely utilized in vibration and noise reduction. However, most elastomers are derived from petroleum-based sources and their functionality are limited to a single purpose. In this work, a biobased polyurethane (bio-PU) elastomer was synthesized from biobased poly(trimethylene ether) glycol, and then a H-bond cross-linking strategy was implemented by incorporating biobased tannic acid (bio-TA) to fabricate biobased PU/TA (bio-PU/TA) damping composites. The structures and performances of the fabricated composites were systematically characterized. The results illustrated that the strong H-bond interactions between bio-PU and bio-TA molecular chains greatly enhanced the mechanical and damping performances of the composites, in which the tensile strength, elongation at break, and tan δ max of bio-PU/TA composites were enhanced by 173.5, 68.7, and 55.4%, respectively. Moreover, the introduction of bio-TA with abundant polyphenol structures remarkably improves the capacity for residual carbon formation and the ultraviolet (UV)-shielding of bio-PU, leading to an upgraded bio-PU/TA composite flame retardancy and enhanced UV-shielding properties in the 280−400 nm UV region. The fabricated bio-PU/TA composites offer a promising strategy for developing damping materials with multifunctional performances.
