2D-to-3D Shape Transformation of Room-Temperature- Programmable Shape-Memory Polymers through Selective Suppression of Strain Relaxation
关键字：Shape-Memory Polymers
Although shape-memory polymers (SMPs) can alter their shapes upon stimulation of environmental signals, complex shape transformations are usually realized by using advanced processing technologies (four-dimensional printing) and complicated polymer structure design or localized activation. Herein, we demonstrate that stepwise controlled complex shape transformations can be obtained from a single...

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 ...

Synthesis of Hierarchical Three-Dimensional Copper Oxide Nanostructures through a Biomineralization-Inspired Approach
关键字：Silk fibroin
Three-dimensional (3D) copper oxide (CuO) nanostructures were synthesized in a regenerated Bombyx mori silk fibroin aqueous solution at room temperature. In the synthesis process, silk fibroin served as the template and helped to form the hierarchical CuO nanostructures by self-assembly. Cu(OH)(2) nanowires were formed initially, and then they transformed into almond-like CuO nanostructures with b...

Fabrication of Superhydrophobic Cellulose-Based Materials through a Solution-Immersion Process,
关键字：Superhydrophobic, Cellulose, Solution-Immersion Process
An industrial waterproof reagent [(potassium methyl siliconate) (PMS)] was used for fabricating a superhydrophobic surface on a cellulose-based material (cotton fabric or paper) through a solution-immersion method. This method involves a hydrogen bond assembly and a polycondensation process. The silanol, which was formed by a reaction
of PMS aqueous solution with CO2, was assembled on th...

Novel Reactive Compatibilization Strategy through Physical Functionalization and/or Coupling
关键字：olyblend, Reactive compatibilization, Functionalization
To perform reactive compatibilization of immiscible A+B polymer blends, component A and/or B must possess certain functional groups. In case neither component A nor B component contains any reactive functional group,&nbs...

Study of shear-induced interfacial crystallization in polymer-based composite through in situ monitoring interfacial shear stress
关键字：crystallization
In order to further investigate shear-induced
interfacial crystallization of polymer-based composites, an
improved fiber-pulling device was designed and built. Its
peculiar characteristic is that a force transducer is assembled
to in situ monitor the variation of interfacial shear stress
between the polymer matrix and pulling fiber. Thus, the
relationship between interfacial shear stress and...
