Macroscopic scale structure change of CTAB/NaSal aqueous solutions in start-up shear flow
A surfactant solution that forms wormlike micelles exhibits one-mode Maxwell type linear viscoelasticity by small deformation but the opaque change occurs uniformly over the entire flow cell when both strain and shear rate in star...

THE EFFECTS OF DIFFERENT METHODS OF ADDING NANO-SiO2 ON MECHANICAL PROPERTIES OF UP/NANO-SiO2 IN-SITU HYBRID COMPOSITES
On the premise of the tetraethyl orthosilicate, hydrolytic silicon sol and the nano-SiO2 powder respectively, a series of unsaturated resins containing nano-SiO2 groups were synthesized by in-situ polymerization. The UP/nano-SiO2 hybrid composit...

Bottom-Up Fabrication of Ultrathin 2D Zr Metal–Organic Framework Nanosheets through a Facile Continuous Microdroplet Flow Reaction
关键字：MOF, Microdroplets
Direct synthesis of the ultrathin and discrete 2D metal-organic framework (MOF) nanosheets is extremely challenging. Herein, we present the first facile continuous bottom-up strategy
for preparing ultrathin (～3 nm) 2D MOF nanosheets with high crystallinity comprising assemblies of a few layers. Unlike conventional solvothermal synthetic methods for 2D MOFs, the weak interlayer interaction ...

MGO/UP复合材料摩擦性能及热性能研究
石墨是优良的耐高温润滑材料，但其表面缺少活性官能团，作为填料时与聚合物基体相容性较差。氧化石墨(GO)是石墨氧化后的产物，其表面含有丰富的含氧官能团，这使其与聚合物基体具有较好的相容性。然而将GO作为不饱和聚酯(UP)复合材料的增强填料，仍存在含氧官能团易分解，与基体树脂相容性不好的难题，因此对GO进行化学改性、提高其在基体树脂中的分散性和相容性很有必要。本文通过Hummers法制备了GO，利用硅烷偶联剂KH-570对G...

Tuning the glass transition temperatures of polymers by up to 100℃: equivalence of confinement effects in multilayer films and polymer blends
The glass transition of a polymer occurs when, upon cooling, chains are no longer able to adopt equilibrium conformations on the experimental time scale. This transition from a disordered, rubbery or liquid equilibrium state to&nb...
