The cover image by Dandan Dou (supervised by Lizhen Wang) shows how biodegradable antibacterial ureteral scaffold samples (PLGA/PCL/AgNP) were prepared by 3D printing. With good biocompatibility, the samples were under a strong inhibitory effect on Escherichia coli and Staphylococcus aureus. AgNP was released continually with the degradation, which can achieve a continuous antibacterial effect. The mechanical properties with AgNP were higher than those without AgNP. It provides a potential way to design ureteral scaffolds based on biodegradable polymers with AgNP in the clinic. DOI: 10.1002/app.54664

Crack Nucleation of carbon black filled rubber compounds.

Through altering the composition of polydopamine the characteristics of the coating can be controlled. This in turn allows for the control of the mineralization of calcium phosphate on the surface of the polymer. Normal PDA (top) does not produce a calcium phosphate layer as robust as the PDA sodium tetraborate hybrid coating (bottom).

Molten ε-caprolactam was used as a green solvent to copolymerize styrene with three types of reactive monomers, namely maleic anhydride (MAH), glycidyl methacrylate (GMA) and 3-isopropenyl-α,α-dimethylbenzyl isocyanate (TMI). The synthesized copolymers were used as compatibilizers to modify the immiscible plant-derived poly(decamethylene terephthalamide)/polyphenylene oxide (PA10T/PPO) blends. The compatibilized PA10T/PPO blend has fine PPO domains and exhibited excellent mechanical strength and heat resistance.

Graphene oxide (GO) has been successfully synthesized from graphite, and silane modified GO (fGO) has been subsequently functionalized by a silane agent. The PCL film and its nanocomposite films have been fabricated using the solution casting method. When the freshness of strawberries has been compared, the PCL/fGO/TiO₂ nanocomposite film has the potential to be used as a food packaging film.

A redox and pH dual-sensitive polymer P407-CS(FA)-SS-CHO was designed and synthesized. The polymer could self-assemble into micelles and encapsulate paclitaxel. The micelles could be selectively uptaken by MCF-7 cells. Both acid and glutathione could trigger the drug release from the micelles. The micelles were potential carriers for paclitaxel delivery.

The fabricated membrane bearing sulfonic acid group shows the desirable nitrate rejection efficiency (90.32%), acceptable solution filtration flux (10.15 L m⁻² h⁻¹ at 0.6 MPa), and decent pure water permeation flux (50.8 L m⁻² h⁻¹ at 0.6 MPa). Additionally, the concentrated nitrate was recycled for the electrochemical intercalation of flake graphite, achieving the resource utilization of NF concentrated solution.

After S³M treatment, the thickness of the graphene sheet was reduced from 40nm to 2nm and uniformly dispersed in the matrix. The friction coefficient is significantly reduced and the wear resistance is also improved.

A novel composite coating was prepared from the acid-activated attapulgite (ac-AT) and castor oil-based polyurethane (PU). Specially, the ac-AT was modified by KH-560 coupling agent and in-situ grafted with stearic acid (MAT). The controlled-release performance of the composite was significantly enhanced due to the optimized hydrophobic and mechanical properties.

This work has developed solution-reprocessible cellulose acetates of enhanced mechanical and rheological properties without losing the transparent appearance by using poly(4-pinacolatoborylstyrene) additives as cross-linkers to enable dynamic polymer network.

For the first time, the successful scheme of preparing room temperature repair poly(siloxane-urethane) coating (PUESi) with alkyl aryl modified silicone polyol (SiOH) and bio-based castor oil (CO) was designed and synthesized.

Solvent (DCM) entrapped in Matrimid® can be removed by soaking in methanol or thermal annealing. Methanol desorbs under mild conditions. Sample history determines the sorption characteristics and phase transitions. Annealed Matrimid® relaxes to the state of the methanol-soaked Matrimid® when exposed to studied volatile compounds.
