Enhancement in the Mechanical Properties and Corrosion Resistance of Waterborne Polyurethane Coatings by Using Titanate‐Functionalized Graphene Oxide

Zhen Li, Y. C. Zhu, Rui Dai, Gaowen Zhang et autres

ABSTRACT To enhance the mechanical strength and chemical resistance of waterborne polyurethane coatings, modified graphene oxide (HGO) was incorporated into cationic waterborne polyurethane (CWPU) via stepwise polymerization to yield HGO/CWPU composite coatings. By modifying GO with bis(triethanolamine) diisopropyl titanate, a triple‐action network …

NIR-Cleavable and pH-Responsive Polymeric Yolk–Shell Nanoparticles for Controlled Drug Release

Xiaotao Wang, Yebin Yang, Gaowen Zhang, Chak Yin Tang et autres

Responsive drug release and low toxicity of drug carriers are important for designing controlled release systems. Here, a double functional diffractive o -nitrobenzyl, containing multiple electron-donating groups as a crosslinker and methacrylic acid (MAA) as a monomer, was used to decorate upconversion …

Mechanical characterizations, recyclability of thermoplastics through melt grafting a dynamic covalent network onto polyethylene

Xinyong Dong, Dezheng Hu, Huaqing Wang, Yiwan Huang et autres

Polyethylene (PE) is the most heavily used polymer worldwide. Theoretically, PE can be further enhanced by methods such as increasing the molecular weight or moderate cross-linking, however these changes lead to increased viscosity and difficulty for processing PE in the molten state, …

Near infrared to ultraviolet upconversion nanocomposite for controlling the permittivity of polyspiropyran shell

Xiaotao Wang, Xiaoping Liu, Hongda Zhu, Gaowen Zhang et autres

Near infrared to ultraviolet (NIR-to-UV) up-conversion nanocomposites, composed of an upconversion nanoparticle (UCNP) core and a transformable polyspiropyran shell, were prepared by distillation precipitation polymerization and the template method. The polyspiropyran shell can undergo reversible hydrophoblic-hydrophilic transformations through the switching of UV …

Synthesis of Yolk–Shell Polymeric Nanocapsules Encapsulated with Monodispersed Upconversion Nanoparticle for Dual-Responsive Controlled Drug Release

Xiaotao Wang, Xiaoping Liu, Li Wang, Chak Yin Tang et autres

Dual-responsive (light and pH) yolk–shell structured drug delivery nanocapsules, each consisting of a movable upconversion nanoparticle (UCNP) core and a shrinkable poly(methacrylic acid) (PMAA) shell, were prepared by distillation precipitation polymerization. Monodispersed NaYF 4: Yb 3+ /Tm 3+ UCNPs were synthesized and …

Dual Ionically Cross-linked Double-Network Hydrogels with High Strength, Toughness, Swelling Resistance, and Improved 3D Printing Processability

Xuefeng Li, Hui Wang, Dapeng Li, Shijun Long et autres

We report a dual ionic cross-linking approach for the preparation of double-network hydrogels with robustness, high strength, and toughness, sodium alginate/poly(acrylamide- co -acrylic acid)/Fe 3+ (SA/P(AAm- co -AAc)/Fe 3+ ), in a facile “one-step” dual ionic cross-linking method. We take advantage of …
