Conductive metallic micropatterns on transparent glass substrates are desired in lots of applications, e.g. electrofluidic devices and micrototal analysis systems. Due to the significant differences in material properties between metal and glass, the fabricated metallic micropatterns prone to show limited bonding strength to the glass substrates. In this paper, microgrooves with porous edge areas are prepared by a laser-induced backside wet etching (LIBWE) method. In the subsequent electroless plating process, this peculiar surface structure enables fast deposition of copper on these areas without further treatment of the surface. Moreover, due to the strong anchor effect caused by the porous microstructures, the obtained copper micropatterns show high bonding strength to the glass substrate. No damage or peeling is observed under 20-min sonication in water and repeated scotch tape test. These micropatterns can even survive from surface polishing by sandpapers. We also demonstrated that this copper micropatterns with low resistivity (1.9 μΩ·cm) could be used for rapid heating of localized surface areas, which may be a potential choice for various microsystems.

Large-area oriented ZnO nanoarrays (including nanowire, nanorod, and nanotube) on ITO glass substrates are synthesized via the simple hydrothermal, electrodeposition, and electrochemical etching approach. The morphology of ZnO nanoarrays is controlled by adjusting the reaction temperature, reaction time, and current density. The scanning and transmission electron microscopy (SEM and TEM) results indicate the successful preparation of large-area oriented ZnO nanoarrays with different types, and the energy-dispersive X-microanalysis spectrum (EDS) and X-ray diffraction (XRD) results confirm that the composition of the obtained nanoarrays is ZnO. More importantly, the as-prepared ZnO nanotube arrays are observed with about a 40% increase in ultraviolet absorption intensity compared to the ZnO nanowire/nanorod arrays, due to having larger specific surface areas. The as-prepared different types of ZnO nanoarrays have great potential for applications in low-cost and high-performance optoelectronic devices.

The aim of this study is to develop a simple method to grow an ultralong hydroxyapatite nanowire coating on a substrate. The ultralong hydroxyapatite nanowire coating on a glass substrate was synthesized by a one-step calcium oleate precursor solvothermal method. The formation process of the nanowire coating on the glass substrate was investigated, and the morphology, crystal phase and apatite-forming ability were studied. Moreover, the as-prepared hydroxyapatite nanowire coating exhibited excellent apatite-forming ability in simulated body fluid. The as-prepared ultralong hydroxyapatite nanowire coating has great potential for various biomedical applications.

Poly(styrene)- b -poly(N-isopropylacrylamide) (PS- b -PNIPAM) amphiphilic diblock copolymers were synthesized via reverse iodine transfer polymerization (RITP) firstly. And then the honeycomb structured porous films were fabricated by drop the amphiphilic diblock copolymer solutions on glass substrates . The porous films were characterized using field emission scanning electron microscopy (FESEM) and atomic force microscopy (AFM), respectively. The results showed that the regular honeycomb patterned porous film was achieved successfully by employing the block copolymer with a significantly larger polystyrene block proportion into the solution and the pore diameter of the film decreases obviously with the polymer concentration increased. The effects of airflow speed and Ag particles on porous films are also discussed in this study.

Due to their wide variety of practical applications, antireflective coatings have been studied intensively. In this paper, we developed a novel approach to fabricate antireflective coatings on glass substrate by using charged chitin nanofibers (ChNFs) and electric field deposition. The ChNFs were obtained via ultrasonic treatment of the modified chitin through partial deacetylation, esterification and esterification followed partial deacetylation (dual modification), respectively. The ChNF coatings prepared by applying electric field deposition and using aqueous dispersions of the dual modified ChNFs had antireflective capacity. The effects of electric field intensity, electric field application time and ChNF dispersion concentration on antireflective capacity of the ChNF coatings were studied. The coating obtained by applying 55 V electric field for 5 min and using the dispersion of the dual modified ChNFs with concentration of 0.05 wt% yielded increase in transmittance of a glass substrate (∼ 2.4% at wavelength of 550 nm). The results of this study demonstrate that electric field deposition is a high efficiency and low cost approach to prepare antireflective coatings on large size and nonplanar substrates with charged nanofibers.

This study focuses on the preparation of silica-sol for producing a durable, transparent, super-hydrophilic coating on glass substrates. The coating was cured within a few minutes at room temperature and exhibited an excellent self-cleaning effect. To obtain the superhydrophilic coating, silica-sol with a certain particle size was prepared and characterized via transmission electron microscopy (TEM). The sol was mixed with a surfactant, crosslinker, solvent, and other components in a certain proportion. The micromorphology of super-hydrophilic coating surface was characterized by scanning electron microscopy (SEM) and atomic force microscopy (AFM). The static contact angle was measured to evaluate the wettability of the coated surface. The contact angle was noticed to have reached to 4.2° after coating. The coating surface remained transparent and self-cleaning with time despite a small increase in the contact angle. Therefore, the coating has a good application potential in the field of self-cleaning solar panels.

The weak adhesion of diamond-like carbon (DLC) films on glass has hindered their widespread application. Despite extensive research on interlayers to enhance adhesion, the challenge of poor DLC adhesion on glass surfaces remains unresolved. In this study, a new strategy is proposed to improve DLC adhesion on glass. Initially, the glass was chemically etched to generate continuous and micrometer-sized pits on the surface. Subsequently, oxygen plasma treatment was employed on the etched glass to increase the Si–OH content on the surface. SiO 2 , SiOC and DLC were then sequentially deposited on the etched glass using magnetron sputtering . The film materials were embedded into the pits, resulting in a wavy 3D morphology. This morphology facilitated the distribution of applied force on the inclined planes of the pits and increased the contact area between the film and the glass surface, thereby improving the chemical bonding between the film and the substrate. The adhesion strength , Vickers hardness and pencil hardness of the films on the glass were 135.37 mN, 751.8 HV and 8H, respectively. These results demonstrate the effectiveness of the proposed approach in addressing the issue of weak DLC adhesion on glass. The findings of this study have potential applications in various fields.

In this study, a rapid thermal process, which can be achieved via the conventional glass tempering process, was utilized to fabricate silica-based superhydrophilic antifogging coatings with micro-nano hierarchical roughness on glass substrates. The effects of SiO 2 nanoparticle and triethylborate loadings on the coatings’ properties have been systematically investigated. Moreover, the formation mechanism of such coatings has been explained. The optimal coatings demonstrate a high level of hydrophilicity with a water contact angle (WCA) of ∼ 0°. Meanwhile, such coatings exhibit good antifogging effect and robustness as well.

Ag triangular nanoplates have been widely used as the SERS substrate due to their anisotropic morphology and sharp corners. In this work, SERS activity of Ag triangular nanoplates on glass and paper substrates was investigated with different concentration and size. A tiny triangular nuclei based synthesis method was employed to produce Ag triangular nanoplates with different size. And the extinction coefficients of Ag triangular nanoplates with different size were quantified by inductively coupled plasma mass spectrometry (ICP-MS) and transmission electron microscopy (TEM). With definite concentration, Ag triangular nanoplates with small size showed stronger SERS intensity on glass substrate at high concentrations, while large Ag triangular nanoplates exhibited better SERS effect on paper substrate at low concentrations. The possible reasons for distinct SERS activity of Ag triangular nanoplates on glass and paper were discussed with scanning electron microscope (SEM) characterization. These results exhibited important implications for fabricating Raman substrates using Ag triangular nanoplates and could be applied to the SERS sensing with flexile substrate.

In this contribution, surface-enhanced Raman spectroscopy (SERS) based on conical holed glass substrates deposited with silver colloids was reported for the first time. It combines the advantages of both dry SERS assays based on plane films deposited with silver colloids and wet SERS assays utilizing cuvettes or capillary tubes . Compared with plane glass substrates deposited with silver colloids, the conical holed glass substrates deposited with silver colloids exhibited five-to ten-folds of increase in the rate of signal enhancement, due to the internal multiple reflections of both the excitation laser beam and the Raman scattering photons within conical holes. The application of conical holed glass substrates could also yield significantly stronger and more reproducible SERS signals than SERS assays utilizing capillary tubes to sample the mixture of silver colloids and the solution of the analyte of interest. The conical holed glass substrates in combination with the multiplicative effects model for surface-enhanced Raman spectroscopy (MEM SERS ) achieved quite sensitive and precise quantification of 6-mercaptopurine in complex plasma samples with an average relative prediction error of about 4% and a limit of detection of about 0.02 μM using a portable i -Raman 785H spectrometer. It is reasonable to expect that SERS technique based on conical holed enhancing substrates in combination with MEM SERS model can be developed and extended to other application areas such as drug detection, environmental monitoring, and clinic analysis, etc.

Efficient activation of donor-type dopants is important for promoting the photoelectrochemical (PEC) performance of semiconductor photoanodes. High temperature annealing, the most often-adopted method, can active the dopants, but is accompanied by serious deterioration of the conductive substrate. Hence, it still remains a challenge to develop a new method to activate the dopants in semiconductor photoanodes deposited on a substrate that is not resistant to high temperature. Herein, we report a pulse laser annealing (PLA) strategy to activate titanium dopant in hematite photoanodes at room temperature to improve the PEC performance for water splitting. A short treatment with 450 nm nanosecond yttrium aluminum garnet (YAG) laser (20 pulses, 30 mJ cm −2 per pulse) causes crystallinity improvement and surface roughening of hematite photoanodes without destroying the fluorine doped SnO 2 (FTO) conductive glass substrate, and results in a 1.85-fold increased photocurrent density (0.484 mA cm −2 , 1.23 V vs. RHE) of Ti-doped hematite photoanodes (5% doping level, Ti:Fe 2 O 3 -PLA). The charge transfer efficiency at the surface of Ti:Fe 2 O 3 -PLA was approximately two-fold higher than Ti:Fe 2 O 3 , and a 10.1-fold increased donor density (1.29 × 10 19 cm −3 ) was achieved, demonstrating the potential of PLA treatment for activating doped semiconductor photoanodes at room temperature.

Superhydrophobic films on glass substrate with robust adhesion and dual pinning to the water droplets were fabricated utilizing a novel in situ polymerized fluorinated polybenzoxazine (F-PBZ) having drooping aliphatic chains and incorporated SiO 2 nanoparticles (SiO 2 NPs). By employing the F-PBZ/SiO 2 NPs modification, the as-prepared composite films possess the robust adhesion to the glass substrate and superhydrophobic pinned state with water contact angle (WCA) of 150° and the non-pinned state with WCA approaching to 165°. Surface morphological studies have indicated that the wettability of the resultant films could be controlled by tuning the surface composition as well as the hierarchical structures. The key role of micro and sub-micro-sized structures and the nanometer sized voids is discussed by the investigation into static contact angle, contact angle hysteresis, droplet evaporation, and propensity for air pocket formation. The as-prepared films exhibited high adhesion toward the glass substrate with considerable durability in corrosive water and proved their simultaneous use in the transportation of micro-droplets, which could be helpful to design large-area and highly scalable superhydrophobic films.
