    Abstract In 2021, the scientific community celebrated the 85th anniversary of the Chinese scientist Academician Wen-Rui Hu. In addition to his innovative contributions to cosmic magnetohydrodynamics (MHD) during his early scientific career, he has initiated microgravity science research in China from the middle of 1980s, and made many pioneering contributions to microgravity fluid physics. He has also promoted researches in China in the fields of space material science, space biotechnology, space fundamental physics, and relevant applications. He is respected as the founder of microgravity science in China because of his eminent pioneering contributions and prominent leadership. This article tries to provide a brief historical perspective of the tireless explorations of Academician Wen-Rui Hu in the field of microgravity science and other relevant disciplines till today based on personal views of his former students and colleagues.

    Abstract Non-covalently modified graphene nanosheets were prepared by reduction graphene oxide with hydrazine hydrate and simultaneous non-covalent functionalization via 1-allyl-methylimidazolium chloride (AmimCl) ionic liquid. Atomic force microscopy revealed that AmimCl ionic liquid modified graphene (IL-G) was well-dispersed in a single exfoliation with a thickness of around 0.96 nm in DMF. Subsequently, the prepared IL-G nanosheets were incorporated into polyurethane (PU) to fabricate IL-G/PU nanocomposites by solution blending. X-ray diffraction disclosed an exfoliated morphology of IL-G nanosheets dispersed in the PU matrix, while the fractured morphology of the IL-G/PU nanocomposites showed that IL-G nanosheets presented a wrinkled morphology when dispersed in the matrix. Both techniques revealed homogeneous dispersion and good compatibility of IL-G nanosheets with PU matrix, indicating the existence of interfacial interactions. At 0.608 wt% loadings of IL-G nanosheets, the tensile strength and storage modulus of the composites were increased by 68.5 and 81.1 %, respectively. High thermal properties were also achieved at a low loading of IL-G nanosheets. An approximately 40 °C improvement in temperature of 5 % weight loss and 34 % increase in thermal conductivity were obtained at just 0.608 wt% loading of IL-G nanosheets.
