Graphical Sticky gels : A novel adhesive hydrogel driven by A-U has been successfully synthesised and investigated (see figure). The hydrogel exhibits remarkable adhesive behaviour for various materials including fresh tissues from mice. The A-U adhesive hydrogels also exhibit iterative durable adhesion for various materials. The bioinspired adhesive strategy created by ribonucleic acid bases should promote the development of soft and wet adhesive materials. Nucleobase pairs of adenine and uracil (A-U) from ribonucleic acid are of particular interest for various promising material properties. Herein, a novel polyacrylamide hydrogel with adhesive properties that are assisted by adenine and uracil has been designed and investigated. The incorporation of adenine and uracil enables the formation of a polyacrylamide hydrogel with remarkable adhesive behaviour with various materials including polytetrafluoroethylene (PTFE), plastics, rubber, glasses, metal, ceramics and wood. Moreover, the adhesive hydrogel can easily and directly adhere to humid biological tissues without any extra process, including heart, liver, spleen, lung, kidney, bone and muscle of mouse. More impressively, even after repeated peeling tests (10×), the AU-mediated polyacrylamide hydrogel still exhibits excellent durable adhesion for various materials. From mechanical contact tests, the adhesion energy of the A-U adhesive hydrogel is 47.9 J m −2 , which is nearly nine times that of polyacrylamide hydrogel (5.3 J m −2 ). The 90° peeling strength for aluminium, titanium, silica rubbers, glasses, PTFE and hogskin is 518, 645, 445, 396, 349, and 119 N m −1 , respectively. The multipurpose and durable adhesive behaviour of hydrogels assisted by adenine and uracil indicated the promise of nucleobase pairs from ribonucleic acid for the future development of adhesive materials.

Adhesive polymers, which contain an unusual amino acid, 3,4-dihydroxyphenylalanine (DOPA), can bind strongly to all organic or inorganic surfaces. However, due to DOPA’s poor solubility in organic solvents, it is difficult for us to get desired adhesive polymers. In this paper, poly(N-benzyloxycarbonyl-3,4-dihydroxyphenylalanine) (PNBD) was synthesized based on the modified L-DOPA. Gel Permeation Chromatography was used to analyze the molecular weight of PNBD. The structure of PNBD was characterized by Fourier Transform Infrared Spectroscopy and Hydrogen-1 Nuclear Magnetic Resonance. The adhesive properties of PNBD were determined by lap shear tensile strength tests. The results indicated that PNBD was prepared successfully and had formidable adhesive performance on the various substrates.

Building photonic crystals on the surface of flexible textiles is a common way to obtain structural color fabrics. However, strict requirements for substrate fabric properties, poor stability of photonic crystals, and the lack of new application scenarios have hindered the promotion and use of structural color materials. In this study, we immobilized polystyrene photonic crystals in a fully encapsulated form on the surface of flexible white cotton fabric. These photonic crystals exhibited bright and iridescent structural colors. The fully encapsulated structure imparted high mechanical stability to the photonic crystals. After conducting mechanical and chemical resistance tests, the structural color fabric maintained an intact photonic crystal structure and a significant structural color effect. We also used the prepared structural color fabric to make adhesive tapes, which could easily adhere to surfaces of different materials (e.g., glass, metals, polymers, etc.) and showed good adhesive properties . The findings of our study not only addressed the limitations of the previous methods of preparing structural color fabrics but also provided a new to use these fabrics in practical situations.

As an alternative approach to superhydrophobic surfaces, slippery lubricant-infused porous surface (SLIPS) is a promising solution to undesirable adhesion. Nonetheless, it is highly expected yet still challenging to exploit a method featured substrate-independence, time-saving property and long-term stability. In this study, different from the common preparation process of SLIPS, the di-particles-derived slippery lubricant-infused porous surface (DPD-SLIPS) was successfully fabricated derived from strategically inverted construction of highly stable and superhydrophobic di-particles framework for locking lubricant via successively-two-step spraying polyacrylate adhesive nanoparticles (NPs) and fluorinated SiO 2 NPs, followed by perfluoropolyether (PFPE) infiltration. This substrate-independent procedure is time-saving and adaptable for a variety of materials with distinct morphologies and dimensions. The resultant surface hierarchy exhibited excellent mechanical robustness and lubricant-locking ability when subjected to adhesive tape peeling, abrasion, and shearing tests. Furthermore, the anti-adhesion performance of the created surface was investigated under diverse conditions, exhibiting remarkable ultra-slipping, drag reduction, anti-biofouling, self-cleaning, and anti-icing properties. In particular, the construction of such low surface energy base with micro/nano hierarchical structure via a facile spraying method is an advanced candidate for real applications in reducing ship drag, marine antifouling, preventing biological invasion, among others.

Comprehensive Summary In nature, fishes have evolved functional skins with effective hydrodynamic performance and anti-fouling, facilitating predation and escaping from predators. Although a large number of fish scale-inspired structured surfaces have been explored, the incorporation of mucus on the structured surfaces has been largely ignored. Inspired by the skin of Osteichthyes fishes, a Janus hydrogel coating (JHC) is successfully prepared by a two-step UV light irradiation at room temperature. The bottom side of JHC (STH) achieves a shear adhesive strength of 103.3 ± 17.5 kPa and can strongly adhere to a large variety of surfaces, including metals, ceramic and polymers. The top surface of JHC (SLH) replicates the structure of cycloid scales, while the nature of hydrogel mimics the mucus on fish skin. SLH possesses prominent mechanical, anti-swelling, anti-fouling and drag reduction properties. The design strategy for JHC has potential applications in numerous fields, like, pipeline transportation, bioengineering, and shipping industry.

Rubber as a substrate exhibits very different surface physical and chemical characteristics from steel. It still remains challenging to achieve a complete interface stripping of steel while maintaining double-sided adhesion between rubber and steel. Hydroxyl-terminated polybutadiene (HTPB) possesses remarkable low-temperature flexibility that contributes to migration and orientation of molecular chains, and contains abundant C = C bonds that facilitate cross-linking reaction. In this work, the hydroxyethyl acrylate (HEA)-terminated waterborne polyurethane (WPUH) adhesive was prepared by introducing HTPB into polyurethane backbone. The impact of HTPB on the properties of WPUH adhesive was investigated by changing HTPB/poly(tetramethylene ether) glycol (PTMG) molar ratio. The reasons for such change were studied focusing on the structure and bonding mechanism of WPUH adhesive. When rubber and steel were bonded together by WPUH adhesive, the rubber would induce non-polar HTPB segments to approach the bonding interface while the steel would attract the polar carbamate groups to its surface. The adhesion was strengthened by the interfacial interaction once WPUH adhesive wetted two substrates. In addition, the 1,2-isomer C = C bonds of HTPB could undergo free radical polymerization with HEA to form a cross-linked network, which improved the cohesion. This study provides a feasible strategy for achieving the goal of effectively bonding rubber-to-steel without residual adhesive stripping.

To effectively remove cooking-generated oil fume fouling, it is necessary to understand the chemical compositions of fouling, its evolution in the aging process, and its effects on adhesion performance. In this study, the fouling was simulated using soybean oil. The chemical compositions after undergoing different aging time were analyzed by GC–MS, 1 H NMR, and so on. The interaction energies were investigated by the molecular dynamic simulation. The analysis results showed that fouling composition gradually evolved from linoleic-linoleic-linoleic triglyceride (LLL), palmitic-linoleic-linolenic triglyceride (PLLn), and linoleic-linoleic-oleic triglyceride (LLO) to primary oxidation products (hydroperoxides) and secondary oxidation products (such as epoxides, alcohols, and aldehydes). The simulation found that the interaction energies between molecules in fouling, between fouling layers, and between fouling and substrate increased continuously during aging. The former two were attributed to the increases in van der Waals interactions, while the latter was attributed to the rise in electrostatic interactions caused by oxidation products. Meanwhile, the weakest interaction energy between two fouling layers was a vulnerability of the fouling adhesion process. The experimental measurement of peeling force of fouling layers and fouling-substrate verified the simulation results. These findings can guide the design and development of the cleaning agents for fouling.

Adhesives have received extensive attention in flexible bioelectronics, wearable electronic medical devices, and biofuel cells. However, it is a challenge to achieve late regulation of performance once polymer-based gels are formed. Here, a double-network organogel composed of a hydrophilic and hydrophobic polymer network and a polyamide acid network was successfully prepared. In diverse liquid environments (including isopropyl alcohol, glycerol, epichlorohydrin, n-propanol, dichloromethane, triethanolamine, ethanol absolute, hydrogen peroxide, and ethyl acetate), the organogel adhesive demonstrated remarkable properties. It exhibits a strong tensile strength of 200 kPa, a high fracture strain reaching 560%, and an impressive adhesion strength of 38 kPa. In addition, the organogel demonstrates exceptional adhesive properties toward polytetrafluoroethylene, plastics, metals, rubber, and glass. Note that the organogel could also regulate adhesive and tough performance by thermally triggering a cyclization reaction even after the organogel has been formed. The strategy provides a new idea for designing soft materials with post-tunability.

Mussel foot proteins (Mfps), which help mussels attach to various surfaces, are considered to be promising biomaterials due to their outstanding adhesive properties. However, limited production and lack of post-translational modifications of tyrosine residues into 3,4-dihydroxyphenylalanine (Dopa) in bacterial expression systems have hampered their applications. In the present study, for the first time we established the expression of recombinant Mytilus galloprovincialis foot protein type 3 variant B (fp-3B) in Escherichia coli ; and achieved its viable production (~51 mg/L). Additionally, the Dopa content and adhesive properties of fp-3B co-expressed using various types of tyrosinases were compared. Consequently, the co-expression of fp-3B construct together with tyrosinase from Verrucomicrobium spinosum (TyrVs) yielded up to 87 mg/L of modified fp-3B; hydroxylation of tyrosine residues accounted for 57.18% by acid-borate difference spectroscopy. The modified fp-3B also showed significant coating and adhesive ability, and its bulk-scale adhesive strength was 2.9-fold higher than that of unmodified fp-3B. Compared with other type 3 mussel foot proteins, the high-yield expression and extensive hydroxylation level of the recombinant protein indicate that fp-3B co-expressed with TyrVs (3B-Vs) has the potential to be widely used as bioglues.

Adhesive hydrogels tend to exhibit poor mechanical property, therefore it’s still challenging to integrate excellent adhesiveness and toughness in one hydrogel. In this work, we utilized a hybrid crosslinking strategy to design an adenine-mediated hydrogel by introducing adenine and N,N′-methylene bisacrylamide (MBA) into polyacrylamide hydrogel. The hybrid crosslinking hydrogel exhibited a tunable adhesive performance and mechanical strength, based on the balance of cohesion and adhesion through changing the contents of acrylated adenine (Aa) and MBA. The hydrogel can adhere to various solid substrate surfaces strongly as well as biological tissue. The hybrid crosslinking hydrogel also exhibited repeatable and durable adhesiveness, which still possessed robust adhesion on aluminum substrate after 20 peeling cycles. In addition, the synergistic effect of the physical and chemical crosslinking in the hydrogel network endowed hydrogel with superior mechanical properties. The hybrid crosslinking hydrogel could be stretched to over 2700% with fracture stress of 127 kPa and toughness of 931 kJ/m 3 . Meanwhile, the hydrogel displayed excellent self-recover ability and fatigue resistance. The adenine-mediated hybrid crosslinking hydrogel shows potential as materials for tissue engineering.

A uniformly dispersed epoxy/polydimethylsiloxane (PDMS) hybrid system was prepared through hydrosilylation and in-situ polymerization reaction. The obtained epoxy/PDMS coating possessed enhanced mechanical and adhesive properties. The hybrid structure of epoxy/PDMS was confirmed by FTIR, 1 H NMR, GPC and SEM, respectively. Results indicated that the tensile strength , elongation at break and shear strength of the epoxy-containing polydimethylsiloxane (EPS) modified PDMS (EPS-PDMS) were increased by 187 %, 185 % and 137 %, respectively, when compared to the pure PDMS. Besides, TGA analysis indicated that the initial degradation temperature of EPS-PDMS was well maintained when compared to that of pure PDMS. Therefore, the convenient strategy of in-situ formation of epoxy reinforcing phase with flexible long-chain siloxane into PDMS effectively integrated the advantages of two incompatible polymers. The prepared EPS-PDMS coatings with enhanced mechanical and adhesive properties show great potential applications in the aerospace and industrial fields as flexible thermal protection coatings.

The development of sustainable functional materials derived from natural biomass is attracting tremendous attention from both academic and industrial fields in recent years. Besides renewability, sustainable polymeric materials are highly expected to outperform fossil fuel-derived analogues, showing the excellent application potentials. In this work, a renewable plant-oil based polymer was synthesized and its copolymers tackified by adenine/thymine-containing monomers could act as pressure sensitive adhesives (PSAs) with good performance attained. The PSAs containing adenine moieties had better adhesive properties compared with thymine-containing copolymers with the same molar ratio of comonomers, on account of its strong π - π stacking of purines . In addition, the supramolecular mixtures with complementary nucleobases could form intermolecular H-bonding interaction, having both enhanced peel and shear strengths over ones with individual nucleobases. The renewable plant oil-based PSAs showed outstanding reusability and robust adhesion to various substrates. More importantly, the long alkyl chains from the plant oil moieties also impart the adhesives with good hydrophobicity , which enables us to use the adhesives in the presence of water or even under water. This work highlights that the utilization of bio-inspired supramolecular interactions provides us with a straightforward and viable strategy for fabricating high performance biomass-based polymeric materials.
