[Display omitted] • A silicone/ZrO 2 sol hybrid coating is prepared by a facile sol–gel procedure. • The covalent bonding of the rigid zirconia structure and the flexible long-chain telomer gives the coating excellent mechanical properties. • The non-leaching antibacterial amphiphilic telomer is self-enriched on the hybrid matrix. • Good self-cleaning, fouling-release, and fouling-resistance performance of coating is achieved. • The coating is highly transparent which can meet the needs of applications in optical instruments, foldable displays, and marine facilities. Achieving a delicate equilibrium between the mechanical and antifouling attributes of silicone-based coatings remains a formidable task. This research unveiled a novel approach to crafting a hybrid antifouling coating through the amalgamation of an amphiphilic telomer, Zirconia (ZrO 2) sol, triethoxyoctylsilane (KH832) and tetraethyl orthosilicate (TEOS) using an uncomplicated sol–gel technique. The amphiphilic telomer, derived from a synthesized antibacterial acrylamide-benzothiazole small molecule, hydrophobic silanes/fluorosilanes, and hydrophilic monomers, was intricately tethered with the ZrO 2 sol, synthesized through the hydrolysis of n-propyl zirconate. The resultant coating achieved exceptional transparency (>98 % transmittance), attributed to the covalent linkage between the robust zirconia structure and the pliable, long-chain telomer. This unique bonding imparted the coating with remarkable characteristics, including high hardness (4–6H), flexibility (∼5 mm bending diameter), wear resistance, and strong adhesion (∼2.89 MPa) to the substrate. Furthermore, the self-enrichment property of the non-leaching amphiphilic telomer within the hybrid matrix contributed to the coating's outstanding self-cleaning capabilities, as well as its remarkable ability to resist fouling, including bacterial adhesion, protein attachment, diatom deposition, and biofilm formation. Overall, our research systematically explored the influence of composition and structure on both mechanical properties and antifouling performance. Ultimately, we sought to advance the development of a high-performance organic–inorganic hybrid antifouling coating poised to address the diverse requirements of applications spanning optical instruments, foldable displays, marine facilities, and various other fields.

[Display omitted] • The first oral-administration near-infrared fluorescence molecular (NS-V) for detection the variation of viscosity was established. • The probe NS-V was developed on the basis of naphthalene and pyridine benzyl chloride salt, and emitted at NIR region (710 nm). • The robust probe NS-V possesses a large Stokes shift (∼262 nm in MeCN) and high signal-to-noise ratio. • The new probe NS-V can elucidate the variations of mitochondrial viscosity in abnormal state cells. • The robust probe NS-V was realized in situ visualization the changes of viscosity in gastritis mice, for the first time. Gastritis is one of the most common digestive disorders and affecting millions of people worldwide. Recent investigations discovered that abnormal viscosity changes in organisms are associated with an increasing number of diseases that cannot be cured or managed. However, the relationship between gastritis and viscosity has not been explored so far due to lacking the suitable tools for in situ detecting the variations of viscosity in stomach. Herein, we developed a new oral-administration fluorescent probe (NS-V) for in situ elucidation of gastritis viscosity variations, for the first time. Based on the TICT mechanism, the probe employs naphthalene as the fluorescence platform, the rotatable single bond as the viscosity sensitive site, N, N -dimethyl as the strong electron donating moiety and the pyridine salt as the strong withdrawing group to enlarge the π-conjugated system to prolong the emission wavelength. Interestingly, NS-V revealed a good fluorescence response for viscosity at the NIR region from a silent "off" state to "on" and demonstrated high sensitivity, large Stokes shift (262 nm in MeCN), and high signal-to-noise ratio. In addition, NS-V could elucidate the altered mitochondrial viscosity in inflammatory cells. More importantly, utilizing these satisfactory features of NS-V , we discovered a significant increase in viscosity in the gastritis mice. Notably, with the assistance of the oral fluorescence molecule, in vivo and in situ visualizing for the first time revealed the positive correlation between viscosity and gastritis. This work provides an important basis for the diagnosis of gastritis and the robust probe developed in this work possesses a potential application in diagnosis of gastritis without any pain.

[Display omitted] • A temperature-responded flame retardant is designed via in - situ Schiff reaction. • Reversible imine crosslinking network endows WPC with flexible processability. • WPC shows the excellent mechanical strength and flame retardancy simultaneously. Wood plastic composites (WPCs) are considered as the next-generation construction and decorative materials because of their mechanical stability and eco-friendliness. The manufacture of high-performance multifunctional WPCs with improved processability is, however, significantly challenging. In this study, we designed a temperature-responsive flame-retardant WPC consisting of a reversible imine crosslinking network. The reversibility of the imine crosslinking network allowed the formation of a loosely crosslinked network during the melt‐processing of the material (170 °C, 100 Hz), resulting in improved processability, with a low melt viscosity of 1.7 kPa‧s and a short stress relaxation time of 1.16 min. Meanwhile, upon cooling, the imine crosslinking network is reconstructed, imparting the flame-retardant WPC with outstanding stress/strain transfer and mechanical properties. More importantly, the unique imine-based crosslinking network accelerates the catalytic charring effect of the WPC, leading to remarkable improvements in terms of the restriction of heat transfer and inhibition of flammable gases, easy achievement of the UL-94 V-0 rating, and effective inhibition of the peak heat release rate (57.3%) and total smoke production (28.5%). Considering the simultaneous improvements in the processability, mechanical properties, and fire resistance of the WPC, this strategy of reversible crosslinking network may open up new opportunities in the development of innovative fibre-reinforced composites.
