Yasushi Maeda et al.
The morphology and crystallization behavior of imidazolium ionenes as crystalline polyelectrolytes, poly(alkylene imidazolium bis(trifluoromethanesulfonimide)) (PCmIm-TFSI) with varying methylene units (m), were systematically investigated....
Regulation of Cross-Domain Chirality Transfer in Chiral Triblock Copolymers [0.03%]
手性嵌段共聚物中跨领域的手性转移的调控
Jun Yuan,Xiang Liu,Yingying Wang et al.
Jun Yuan et al.
The formation of the helical phase from the self-assembly of chiral diblock copolymers is attributed to the twisting and shifting of the microphase-separated domain. With the introduction of midblock in-between achiral and chiral blocks, th...

Both polymer size and chain elasticity depend on long-range bond correlations, which determine the chain Kuhn length. These correlations are gradually cut off with increasing externally applied force or polymer confinement, thereby decreasi...
Polymeric Sunscreen via the Biginelli Reaction and Sequential C-S Coupling Reaction for UV Protection [0.03%]
通过Biginelli反应和连续C-S偶联反应制备聚合物型防晒剂用于紫外线防护
Yuhang Jiang,Xinxin Wu,Wenqian Chen et al.
Yuhang Jiang et al.
Excessive ultraviolet (UV) radiation poses significant adverse health effects on humans, underscoring the critical need for novel sunscreen agents. Conventional small-molecule UV filters often suffer from drawbacks such as percutaneous abso...
Impacts of Polymer Adsorption on Adhesion Strength at Solid Interfaces [0.03%]
聚合物吸附对固-solid界面上黏附强度的影响
Reiki Eto,Tatsuki Abe,Yuma Morimitsu et al.
Reiki Eto et al.
Polymer adhesion on solids is governed by chain aggregation at interfaces, yet isolating intrinsic adhesion strength (G0) from complex failure modes has remained elusive. Here, a surface and interfacial cutting analysis system (SAICAS) was ...
Enhanced Spreading of Viscous Macromolecular Fluids on Phase-Separated Aqueous Interfaces [0.03%]
在相分离的水界面上增强粘性大分子流体的铺展性能

Feipeng Chen
The spreading and wetting of liquids on surfaces are ubiquitous in nature and industrial applications. Conventionally, highly viscous macromolecular fluids (e.g., honey and silicone oils) are hard to spread on various surfaces compared to l...
Ellipsometric Characterization of Network Topology Transition in Vitrimers [0.03%]
椭偏法表征交联可重构聚合物的网络拓扑转变
Yuming Wang,Jaylen Davis,Travis L Thornell et al.
Yuming Wang et al.
Vitrimers are an emerging class of covalent adaptable networks, which can be reprocessed at elevated temperatures while preserving crosslinking density. In these systems, the onset temperature of bond exchange is often dubbed "topology free...
Balancing Toughness and Antibacterial Activity of Polylactide Blends with Imidazolium-Based Polymers [0.03%]
