This study aims to develop a self-dispersive and reactive carbon black (DRCB) to improve its application in cotton fabric. CB was functionalized with γ-aminopropyl triethoxysilane (KH550) and then grafted with as-synthesized compound to obtain aqueous phase DRCB. FTIR analysis confirmed the successful grafting of as-synthesized compound onto KH550-modified CB surface. The weight grafting of DRCB on DRCB-15 % dyed cotton fabric was approximately 15.18 %, with a half weight grafting time of around 17 min. TEM observation demonstrated that DRCB had a core-shell structure with the mean sizes of 36.02 ± 4.30 nm. Particle size analysis revealed that DRCB had smaller average aggregate size of 110.3 nm and higher zeta potential of −33.7 mV than CB, indicating that DRCB had much better dispersion in aqueous media than CB. Cotton fabric was effectively dyed with DRCB, providing excellent color depth of 60 (K/S value) with dry rubbing and wet rubbing/washing color fastness of Grade 4 and Grade 3, respectively. DRCB dyed cotton fabric exhibited outstanding anti-UV and anti-static properties, with no significant difference in softness and tensile property before and after dyeing. This research proposed a new method to solve nanoparticle agglomeration and prepare textile dyes with excellent self-dispersivity and reactivity.

Industrial grade carbon black was pretreated and used for adsorption of triclosan (TCS) in water, and its adsorption performance was investigated by static adsorption experiments and fixed bed adsorption experiments. The effects of pH and temperature on the adsorption capacity were investigated and the adsorption performance of carbon black and activated carbon on TCS was compared. As the pH or temperature decreased, the adsorption of TCS by carbon black increased. Carbon black had a maximum adsorption capacity of 18.62 mg/g on TCS, which was somewhat lower than the activated carbon. Furthermore, the breakthrough time increased with increasing bed height, decreasing flow rate and decreasing initial TCS concentration in the fixed bed adsorption studies. The breakthrough time was 14.33 days at a bed depth of 4.2 mm, a flow rate of 2 mL/min, and an initial TCS concentration of 0.5 mg/L TCS. The model from The Bed Depth Service Time (BDST) was well-fitting.Keywords:carbon black;triclosan;adsorption;BDST model

Biodegradable films mitigate plastic pollution but often lack UV-aging resistance, shortening their lifespan. While anti-aging additives can boost the films' durability, small molecule migration constrains the extension of their service life. This study introduces a straightforward solid-phase reaction for producing carbon black (CB) grafted with the UV absorber UV531, termed CB-UV531. This material was then blended with the biodegradable polymer PBAT and transformed into a film via blow molding, yielding a durable UV-resistant biodegradable film (PBAT/CB-UV531). This solid-phase grafting reaction does not require any solvents, thereby reducing solvent contamination and waste, and it is simple to operate, allowing for scalable production. Compared to the unmodified CB, the obtained CB-UV531 exhibits significantly improved thermal stability, which can effectively reduce the loss of UV531 during the subsequent high-temperature film-blowing process. Furthermore, the chemically bonded UV absorber on the surface of CB-UV531, coupled with its reduced particle size, promotes enhanced dispersibility and consistent stability within the PBAT/CB-UV531 film, markedly improving its long-term resistance to UV aging. This method is expected to enhance the anti-aging effects of various commercial light stabilizer additives and can be used to extend the lifespan of different biodegradable materials. Highlights A simple solid-phase reaction method was developed to prepare CB-UV531. CB-UV531 reveals smaller size and superior dispersibility. Biodegradable PBAT/CB-UV531 film was prepared via a blowing process. UV531 migration loss in PBAT/CB-UV531 film is significantly reduced. PBAT/CB-UV531 film shows enhanced thermal stability and aging resistance.

An aqueous dispersion of carbon black is crucial in industrial coatings. In this manuscript, a hyperdispersant IBOMA-MPEGA-DMAM (IMD) has been synthesized using isobornyl methacrylate (IBOMA), polyethylene glycol monomethyl ether acrylate (MPEGA), and N, N -dimethyl acrylamide (DMAM) as monomers via a free radical polymerization method, which is used to improve the dispersibility of an aqueous dispersion system of carbon black. The molecular structure and performance stability of IMD were investigated through comprehensive characterizations of FTIR, GPC, particle size distribution and TEM. When the molar ratio of the monomers IBOMA:MEPGA:DMAM is 5.5:8.3:9.7, the obtained hyperdispersant shows good dispersibility. When the optimal dosage of dispersant IMD was 8%, the viscosity of carbon black slurry was as low as 18.6 mPa·s and the average particle size of carbon black was 275 nm. Furthermore, the stability of the prepared carbon black slurry was better than that of the two commercial dispersants.

Efficient synthesis and controlled modification of carbon dots (CDs) with tuneable properties on the basis of facile technical routes are of great significance for user-defined applications as well as more insightful understanding of the unique fluorescence from carbon nanomaterials. In this work, we report an improved nitric acid oxidization method towards low-cost and rapid preparation of fluorescent CDs. This is achieved by using industrial carbon black specimens as the precursor and implementing a reduced pressure distillation for the purpose of eliminating excessive acids. Unexpectedly, the product exhibits an interesting dual luminescence behaviour with tuneable characteristics that differs from all previously reported CDs. The strongest emissions at fixed or varied excitations can be simultaneously tuned from blue to green or yellow by simply prolonging the time of acid oxidization. These emissions show distinct stabilities in acid and alkaline environments, thereby making the resultant CDs very promising candidates for pH probes. It is further revealed that this simple synthesis and fluorescence tuning strategy is also applicable to CDs from other carbon blacks.

Water evaporation is a ubiquitous natural process than can be applied to generate electricity through hydrovoltaic effect. However, it remains a great challenge to construct an evaporation system that can satisfy both high-efficiency evaporation and stable power output due to their differences in water managements. Herein, we demonstrate a sandwich membrane strategy to construct a three-dimensional (3D) asymmetric evaporator for efficient tandem solar water-electricity generation by coating two carbon black (CB)/polyvinyl alcohol (PVA) functional films with different channel structures and water uptake at two opposite sides of a wood chip. Owing to the smart self-regulating property of the thin PVA skin and the superior thermal utilization performance of the 3D structure, the fabricated device achieves high evaporation rate of 1.93 kg m −2 h −1 . More importantly, the asymmetric water distribution of the evaporation unit and the confined nanochannels of the dense PVA network render the generator with stable and efficient power output, and the simple connections of several units in series and/or parallel can easily power a commercial calculator, electrolyze methylene blue solution, and light up light emitting diodes , which well proves the conception of combining solar water evaporation and electricity generation in an integrated device.

In this paper, Pt supports on carbon black powder (Vulcan XC-72) were synthesized via a hydrothermal method for selective catalytic reduction (SCR) of NO with H 2 in the presence of 2 vol% O 2 over a wide temperature of 20–300 °C. The results showed that the 3 and 5 wt% Pt/C catalysts resulted in high NO conversion (>90 %) over a temperature range of 120 to 300 °C, and the maximum NO conversion of 98.6 % was achieved over 5 wt% Pt/C at 120 °C. Meanwhile, the influence of SO 2 and H 2 O on the catalyst performance of 3 wt% Pt/C was investigated. The catalysts exhibited good SO 2 poisoning resistance when the SO 2 concentration was lower than 260 ppm. Moreover, a positive effect on NO conversion was detected with the addition of 3 and 5 vol% H 2 O in the feed gas stream.

The structures and properties of natural rubber (NR) obtained from latex with small and large rubber particles (SRP and LRP) are obviously different, while carbon black (CB)/SRP or CB/LRP composites have rarely been reported. In this work, SRP and LRP are separated from natural rubber latex (NRL). The properties of obtained NR/CB composites are systematically investigated as a function of SRP and LRP mass ratios. It shows that the nitrogen content of SRP (1.32%) is much higher than that of LRP (0.10%). Mechanical properties increase with the increase of LRP content because plenty of agglomerates exist in SRP/CB composite whereas LRP/CB composite shows a homogeneous dispersion. Furthermore, a possible model is proposed to illustrate the transformations of agglomerates during stretching and dynamic compressing process. This study provides a new perspective for the design of NR materials through the selection of rubber particles in NRL.

The efficient utilization of low-grade thermal energy to produce clean water or electricity is important because it potentially relieves our demand on limited natural water and energy resources. Here, we propose a dual-functional device to couple solar-driven water evaporation and evaporation-induced power generation for concurrent production of clean water and green electricity. Our strategy involves the fabrication of an asymmetric, dual-layered structure by spraying a carbon black/polyvinylidene fluoride mixture onto bamboo filter paper (CB/PVDF@BFP). The upper CB/PVDF layer serves as a light-to-thermal transducer for instantaneous heating, while the bottom BFP layer functions as a hydrophilic porous platform to boost water uptake and transfer. Moreover, water evaporation drives capillary flow of ions on the conductive CB/PVDF layer to create a pseudostream that can be harnessed for power generation. Notably, our dual-functional device delivers a fast water evaporation rate of 1.44 kg m−2 h−1 and a high energy utilization rate of 92% under one sun, beyond the previous carbon-based reports. Through this solar-driven water evaporation process, we achieve the efficient desalination of artificial seawater and decontamination of organic-polluted water by up to 99.8% and nearly 100%, respectively. Our device also concurrently produces high, consistent evaporation-induced electrical outputs with VOC and ISC of 0.32 V and 1.5 μA, respectively. The generated electrical outputs can be easily stored by charging a capacitor to over 1.5 V within 15 minutes and be subsequently utilized on demand to power common household electronics. By enabling the efficient coupling of multiple solar-driven processes, our work will catalyze the design of next-generation multifunctional devices to ensure electricity and potable water are easily accessible by everyone, especially remote areas without power stations and/or water treatment facilities.

In this study, carbon black (CB) and carbon (coal-tar pitch-based spherical activated carbon (SAC)) were used to successfully fabricate composite-type SAC (CB/coal-tar-pitch-SAC), and its surface was coated with TiO2 to produce the composite material TiO2/CB/coal-tar-pitch-SAC. CB helps in decreasing the pore size of CB/coal-tar-pitch-SAC and increasing its specific surface area and total pore volume, which can be verified by the Brunauer–Emmett–Teller (BET) method. Practically, TiO2/CB/coal-tar-pitch-SAC can sterilize the bacteria present in the water. This study intensively verifies the high reusing sterilization capacity of TiO2/CB/coal-tar-pitch-SAC. The results indicate that TiO2/CB/coal-tar-pitch-SAC can effectively improve the water environment.

This paper clarified the network structure of the lithium-ion battery (LIB) slurry under effects of composite conductive agent amount and carbon black (CB) to graphene (Gr) mass ratio ( m’ CB : m’ Gr ). Four different amounts of composite conductive agent which are φ com1 = 0.25%, φ com2 = 0.5%, φ com3 = 0.75% and φ com4 = 1% are selected as the conductive materials for LIB slurries. Meanwhile, to discriminate the individual impacts of CB and Gr, two distinct mass ratios of CB to Gr, namely, m’ CB : m’ Gr = 1:2 and m’ CB : m’ Gr = 2:1, are additionally chosen. Moreover, the influence of single conductive additive agent CB or Gr with the same amount as composite conductive agent on the network structure of the LIB slurry is also investigated. Furthermore, Electrochemical Impedance Spectroscopy (EIS), Scanning Electron Microscopy (SEM) and Raman experiments are performed to obtain the electrochemical, morphological and Raman characterizations of LIB slurry, respectively. After analyzing the experimental results, the main conclusion shows that the synergistic interaction between CB and Gr ensures a high-level conductive efficiency because of minimizing the amount of the conductive agent and increasing the amount of LiCoO 2 particles to the utmost degree, which has the potential to substantially elevating the energy density of LIB.

Pigments and organic acids are among the most common impurities in complex sample matrices. Their presence in the samples often interferes with the detection of trace analytes. This study aimed to design and develop magnetic materials (GCB/Fe 3 O 4 -PSA) for the efficient purification of organic acids and pigment impurities in sample matrices. We employed the acid modification method to enhance the modification of magnetic Fe 3 O 4 by the primary secondary amine adsorption group (PSA), effectively boosting its adsorption performance. This modification technique not only retains the inherent adsorption characteristics of Fe 3 O 4 but also avoids the irreversible damage to Fe 3 O 4 ′s own adsorption by traditional grafting methods. Subsequently, Fe 3 O 4 -PSA and graphitized carbon black (GCB) were combined through a simple physical assembly method to prepare GCB/Fe 3 O 4 -PSA, which was used for the purification of pigments and organic acids in complex matrices. During the purification process, GCB/Fe 3 O 4 -PSA can be rapidly magnetically separated. After six reuses, the adsorption performance remains above 80 %, fully demonstrating the rapid purification ability and reusability potential of GCB/Fe 3 O 4 -PSA. Compared with unmodified Fe 3 O 4 , GCB/Fe 3 O 4 -PSA significantly enhanced the purification effect of complex matrices. Its adsorption capacities for chlorophyll and ascorbic acid increased by 276.9 % and 263.9 % respectively. After combining with the GCB/Fe 3 O 4 -PSA purification material, cathinones in complex matrix samples (tea, apples, carrots) were determined using UPLC-MS/MS. The recoveries in spiked samples ranged from 96.35 % to 104.17 %, with the RSDs < 3.02 %. Simultaneously, characterization methods such as SEM, FTIR, XRD, VSM, XPS, and BET were used to study the surface structure and chemical composition of GCB/Fe 3 O 4 -PSA. The above results highlight the outstanding performance of GCB/Fe 3 O 4 -PSA in the efficient purification of organic acids and pigments in complex matrices and also show its considerable application potential in the pretreatment of complex matrix samples.
