Bacterial infection and insufficient osteogenic activity are the main causes of orthopedic implant failure. Conventional surface modification methods are difficult to meet the requirements for longterm implant placement. In order to better regulate the function of implant surfaces, especially to improve both the antibacterial and osteogenic activity, external stimuli-responsive (ESR) strategies have been employed for the surface modification of orthopedic implants. External stimuli act as "smart switches" to regulate the surface interactions with bacteria and cells. The balance between antibacterial and osteogenic capabilities of implant surfaces can be achieved through these specific ESR manifestations, including temperature changes, reactive oxygen species production, controlled release of bioactive molecules, controlled release of functional ions, etc. This Review summarizes the recent progress on different ESR strategies (based on light, ultrasound, electric, and magnetic fields) that can effectively balance antibacterial performance and osteogenic capability of orthopedic implants. Furthermore, the current limitations and challenges of ESR strategies for surface modification of orthopedic implants as well as future development direction are also discussed.

“…The thermally unstable urea group then underwent a deblocking reaction under heating conditions to regenerate the −NCO group, allowing for further polymerization with the chain extender . This dual curing method involving heat and UV light enhanced the mechanical properties of the material. − The study also investigated the effects of isocyanate, chain extender, and diluent on blocking silicone urethane acrylate (SiBPUA). A comparison of material properties before and after thermal-curing was conducted to enhance molecular polymerization, resulting in a material with high strength and toughness.…”

Single UV-curing silicone-modified polyurethane acrylate materials have limitations, such as low molecular polymerization and weak mechanical properties compared to thermal-curing materials. This experiment synthesized a polyurethane prepolymer coated with isocyanate groups using hydroxyl polyether silicone oil (PDMS) and diisocyanate. tert-Butylaminoethyl methacrylate (t-BAEMA) was then utilized to create a silicon-modified polyurethane acrylate (SiBPUA) prepolymer with heat-unstable urea and photosensitive groups. This prepolymer was incorporated into photosensitive resin materials and processed through 3D DLP 3D printing. Upon heating, the −NCO group regenerated, and the chain extender underwent a secondary curing reaction, increasing molecular weight and improving performance. The study investigated the impact of different reactants on SiBPUA properties, deblocking temperature, optimal curing temperature, and enhancement of UV-curing materials through thermal curing. The results revealed that the use of isophorone diisocyanate (IPDI), 4,4′-diaminodicyclohexylmethane (PACM), and methyl methacrylate (MMA) resulted in the best mechanical properties. Furthermore, UV-thermal dual curing significantly enhanced tensile strength (12.5 MPa) and elongation at break (219.5%), broadening the application potential of UV-curing 3D printing materials.

The growing high standard of people's wear has put forward requirements for fabrics, and multifunctional fabrics have been developed precisely in response to the requirements of the times. However, the incineration of waste fabrics produces a large amount of pollutants, resulting in a massive waste of resources and environmental pollution. Herein, the degradable nanofiber yarns (NYs) with self-cleaning properties were fabricated by in situ growth of SiO 2 nanoparticles on the surface of the electrospun poly(p-dioxanone) (PPDO) NYs using the Stober method. Then, the PPDO NYs were blended with carbon fibers and the PPDO/SiO 2 NYs with themselves to form the Janus PPDO fabrics, respectively. The Janus PPDO fabric offered asymmetric wettability and dual personal thermal management properties. The PPDO/C side of the Janus PPDO fabric provided 65.8 °C at 1.5 V or 58.5 °C under one sunlight intensity for radiative heating. The PPDO/SiO 2 side exhibited high solar reflectivity (81.8%) and mid-infrared (MIR) emissivity (99.1%), which reduced the skin temperature by 4.6 °C, resulting in radiative cooling. Moreover, the Janus PPDO fabrics display an excellent electromagnetic interference (EMI) shielding performance (53.3 dB). Therefore, yarn-based degradable Janus fabric has a promising future in multifunctional wearable products.
