Spinel-type titanium-based lithium-ion sieve H 4 Ti 5 O 12 has excellent theoretical adsorption capacity and selectivity. Still, spinel-type lithium adsorbents prepared in existing studies have poor adsorption, poor recyclability, and difficulty in recovery. To solve the above problems, composite mesoporous ion sieves, Polyvinyl Butyral-H 4 Ti 5 O 12 –1 (PVB-HTO-1) modified with dual surfactants, were synthesized for the first time in this paper. Hydrophilic lithium-ion sieve HTO-1 with a mesoporous structure was synthesized by adding two surfactants, CTAB and F127. Then the modified ion sieve was composited with PVB to make a fine rod-like composite material, PVB-HTO-1, with a diameter of no more than 0.5 mm, to solve the limitation of the industrial application that the recycling of powdered ion sieve is difficult. The bi-component surfactant-derived ion sieve, PVB-HTO-1, exhibits superior hydrophilicity and possesses a porous mesoporous framework that facilitates ion exchange processes, achieving adsorption equilibrium within a timeframe of three hours. It demonstrates a remarkable maximum adsorption capacity of 53.25 mg/g. Even after undergoing five cycles of adsorption and desorption, the material's adsorption capacity remains at over 90 % of its initial value, indicative of its robust cyclic stability. The uptake of Li + ions by PVB-HTO-1 aligns with the pseudo-second-order kinetic model and conforms to the Langmuir isothermal adsorption model.

Transparent conductive films (TCFs) are highly desirable for making full use of solar energy. However, the production and application of TCFs are seriously restricted by two obvious weaknesses: complex processes and poor properties. In this research, simple and direct approaches including condensation reflux and hot-pressing are selected to gain a cheap TCF with good properties. The polyvinyl butyral enhanced by 6 spray layers of Ag nanowires (AgNWs/PVB) TCF is found to achieve an optical transmittance of 80.1% and a sheet resistance of 86.4 Ω/sq, and meanwhile, withstand bending cycles over 150 and an extensile rate of 15%. Additionally, the AgNWs/PVB TCF has a deep potential to be further improved by hot-pressing treatment and its sheet resistance can be reduced to 19.7 Ω/sq. Our findings may show a facile way to produce low-cost and high-performance TCFs.

In this work, the kinetics of the polyvinyl butyral (PVB) synthesis reaction catalyzed by the deep eutectic solvents (DESs) at the low-temperature stage was studied to control the particle size of PVB resin and optimize its synthesis process. The effects of stirring speed, the concentration of polyvinyl alcohol (PVA), catalyst dosage, and temperature on the synthesis reaction of PVB were investigated. The data obtained from kinetic experiments at 283.15–298.15 K were fitted with the shrinking core models, and the results showed that the model controlled by internal diffusion fitted well with the experimental data. The internal diffusion coefficient, D A , of n-butanal in the product layer was further calculated by the obtained model parameters, and it was applied to predict the synthesis reaction of PVB at different concentrations of n-butanal. The results indicated that the shrinking core model controlled by internal diffusion is suitable to describe the kinetics of the PVB synthesis reaction. DES played a dual role in catalysis and dispersion in the synthesis of PVB, and it was a green catalyst with good potential for PVB industrial applications.

Herein, a porous heddle of poly(vinyl butyral) (PVB) was successfully prepared by thermally induced phase separation with PEG400. A phase diagram of PVB was presented, and the effects of various parameters, such as polymer concentration, extrusion temperature, quenching temperature and take-up speed, on the morphology and properties of the PVB porous heddle were investigated. The pore size and porosity of the heddle increase as the extrusion temperature increases. Furthermore, upon increasing the quenching temperature during the TIPS process, the pore size and mechanical properties decrease, whereas porosity increases. In addition, due to the substantially unchanged crystallinity of the PVB heddle, the tensile strength increases since porosity decreases with the increasing take-up speed. The porosity of the prepared PVB porous heddle reached up to 74.63% when the PVB concentration, the quenching temperature and the extrusion temperature were 20 wt%, 0 °C and 170 °C, respectively. Thus, this porous heddle exhibiting a biconnected structure and significant mechanical properties is promising in the field of porous carrier materials.

Due to the increasing use of laminated safety glass, the issue of polyvinyl butyral (PVB) resource waste has become increasingly serious. The complex composition of waste PVB presents significant challenges for recycling and application. In this paper, PVB was first grafted with phthalic anhydride (PA) to investigate the effect of the modification process on the coating film and coated fabric, thereby guiding the modification research on recycled PVB (rPVB) and successfully preparing rPVB-P. The results indicate that the optimal modification process for PVB involves a modification temperature of 70°C, a modification time of 6 h, and 6 g of PA. The feasibility of applying the prepared coated fabric in the field of trademark ribbon fabric was examined. The surface structure of the coated fabric, prepared with a kaolin mass fraction of 30%, was found to be uniform, with an ink contact angle of 20.32°, and the color fastness to washing and rubbing reached levels 4–5. The overall performance of the coated fabric prepared with rPVB was similar to that of the PVB-coated fabric, demonstrating that rPVB can effectively replace PVB for coating preparation.

Monodispersed and spherical β-TCP granules for 3D printing were prepared by spray drying with the surface modification of PVB . Modifier PVB attached to the particle surface to form the crosslinked network structure and keep them combine with each other into aggregates. The morphology, size, forming performance and crushing behavior of granules as well as the microstructure and density of as-fabricated β-TCP ceramics were used to optimize the PVB contents. Promising results could be expected that PVB contents were 1.0 wt.% and the average particle size of granules was 37.36 μm. The modified granules exhibited excellent forming performance with monodispersed and spherical aggregates for 3D printing . They could be completely crushed under 80 MPa without obvious inter-granules void. These granules with 1.0 wt.% PVB had defined strengths for ceramic forming. The good dispersity and flowability assured the high density and uniform porous structure of β-TCP ceramics, which were used as biological ceramic materials and completely met the standard for bone tissue engineering .

Subsphaeroidal SiC/polymer composite granules with good flowability for additive manufacturing/3D printing of SiC were prepared by ball milling with surface modification using polyvinyl butyral (PVB). PVB adheres to the particle surface of SiC to form a crosslinked network structure and keeps them combined with each other into light aggregates. The effects of PVB on the shape, size, phase composition, distribution and flowability of the polymer-ceramic composite powder were investigated in detail. Results show that the composite powder material has good laser absorptivity at wavelengths of lower than 500 nm.Keywords:SiC;ceramic/polymer composite powder;3D printing;ball milling;surface modification

A novel environment-friendly composite coating (P/P'-Ch-P/P') was prepared by layer-by-layer assembly of polyvinyl butyral (PVB), polymethylhydrosiloxane (PMHS) and chitosan (Ch) on AA 2024 substrate to improve the corrosion resistance of AA 2024 sample. The properties of the coatings were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscope (SEM) and laser confocal microscope. The results showed that the addition of PMHS increased the hydrophobicity of composite coating；as the intermediate layer, Ch also crosslinked other components while forming the film. At the same time, the corrosion resistance of the coating in 3.5 wt.% NaCl solution was characterized by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization. Compared with the bare aluminum substrates, the impedance modulus of the composite coating was increased by 3 orders of magnitude; the corrosion current density (Icorr) of the composite coating was reduced by 5 orders of magnitude. The results of long-term immersion test showed that the composite coating still had good anticorrosion ability after 60 days. This study provides a simple and environment-friendly method for corrosion protection of aluminum alloy in marine environment.

Design and constructing high performance filtration membranes for oil purification from emulsified oil/water mixtures with good durability and self-healing property is highly desired for the remediation of oily wastewater and oil recycling caused by oil leakage and oil spill, but remain a tough challenge. Herein, a facile and environmentally friendly method for fabricating dodecyltrichlorosilane grafted polyvinyl butyral/silica sol/silica nanoparticles composite nanofibrous microfiltration membranes is developed. The as-prepared nanofibrous membranes exhibited intriguing wetting behaviors, such as superhydrophobicity in air and under oil, small sliding angle, and extremely low adhesion force. The superwettability, hierarchical porous structure, and good mechanical properties endowed the membranes with fascinating emulsion separation performance towards highly emulsified oil/water mixtures, involving high separation efficiency >99.6%, large oil permeation flux of ∼2316.2 L m −2 h −1 , and excellent long-term cyclic performance in 10 cycles. Additionally, the as-prepared nanofibrous membranes exhibited superior self-healing performance against external force and maintained good emulsion separation performance after 10 abrasion-repairing cyclic processes. The successful fabrication of such nanofibrous membranes provides a versatile strategy for developing materials with high purification performance, good repairability, and excellent durability for the oily wastewater remediation, oil spill clean-up, and oil purification.

The chain dynamics heterogeneity of the poly(vinyl butyral) (PVB) plasticized by triethylene glycol bis(2-ethylhexanoate) (TEG-EH) was investigated by various solid-state NMR techniques. The plasticized PVB shows two domains in distinct molecular dynamics differences, namely, rigid and soft domains, where the latter is the plasticizer-rich domain. The time domain low field NMR was first used to investigate the dynamics heterogeneity of the plasticized PVB, and the results show the decreasing activated energy of components in the soft domain of plasticized PVB ( E a =20.2 kJ/mol) as compared with that of the pristine one ( E a =24.3 kJ/mol). Detailed dynamics heterogeneity was obtained by high-field NMR with site-specific features. The quadrupole-echo 2 H-NMR was adopted to elucidate the dynamics heterogeneity of the vinyl alcohol (VA) units, where only the hydroxyl group of VA is deuterated. The 1 H- 13 C WISE NMR spectra show that there is not much difference in the mobility of the VB unit in PVB with and without plasticizer, whereas the glass transition temperature differed by approximately 53 °C. This is further supported by Torchia’s T 1 relaxation measurements. The origin of such an unusual phenomenon is attributed to the critical role of the remaining VA (∼22%) in the soft domain, where the VA units locally aggregate through hydrogen bonding. Also, the existence of a mobility gradient in the VB unit has been demonstrated. Moreover, the mobility difference for VB with different stereo-geometry ( meso or racemic conformation) is observed for the first time. This indicates the importance of modulating the ratio of meso over racemic VB for controlling the macroscopic performance of PVB.

The growing demand for sustainable packaging has accentuated the urgent need for high-performance, environmentally friendly coatings. In this study, we proposed a low-cost and industrially applicable one-step dip-coating strategy that integrates poly(vinyl butyral) (PVB) with stearic acid (SA) to construct multifunctional coatings on bamboo fiber paper. PVB established hydrogen bonding with cellulose, forming a dense and continuous film that acted as a robust physical barrier and adhesive matrix. Concurrently, SA molecules interacted with PVB or cellulose through their carboxyl groups, whereas their long alkyl chains self-assembled during curing to generate hierarchical micro/nanostructures, thereby markedly reducing the surface energy. The synergistic interplay between PVB and SA produced a dual-repellent interface, in which PVB ensured film compactness and adhesion, whereas SA imparted pronounced hydrophobic and oleophobic characteristics. As a result, the modified bamboo fiber paper exhibited a high water contact angle of 136.41 ± 1.98°, an oil resistance grade of 12, and a tensile strength of 25.30 MPa─representing a 3.26-fold improvement over the unmodified substrate (7.76 MPa). This strategy demonstrated a facile, economical, and scalable route for producing multifunctional, eco-friendly paper coatings with substantial potential for sustainable food and medical packaging applications.
