Abstract Commodity fraud poses significant economic and public health risks while jeopardizing market stability. A promising avenue for addressing this issue involves the incorporation of physical unclonable function (PUF) in anti‐counterfeiting labels commodity authentication purposes. PUFs are a large number unbreakable security generated through random process, which exhibit unique pattern responses that impervious to replication. In particular, novel kind PUF model, called structural...
Developing a shape memory polyurethane with high mechanical properties, excellent self-healing has become huge challenge for the development of smart materials. Herein, we report design and fabrication network terminated coumarin units (HEOMC-PU) to address this conundrum. The synthesized HEOMC-PU exhibits exceptional performance breaking elongation 746% toughness 55.5 MJ·m–3. By utilizing dynamically reversible behavior repair damaged network, efficient (99.2%) is obtained. In addition,...
Smart materials with outstanding self-healing and reprocessable capabilities are highly desirable for next-generation coatings that can repair damaged in a timely autonomous manner. However, their prevalent use practical applications is currently hindered by various limitations, such as low mechanical strength, long healing time, expensive raw materials. Herein, we prepared epoxy resin coating (EP-SS-DAAX) excellent properties incorporating dynamic disulfide bonds flexible chains into the...
Abstract Physical unclonable function (PUF) is attractive in modern encryption technologies. Addressing the disadvantage of slow data storage/authentication optical PUF paramount for practical applications but remains an on‐going challenge. Here, a highly efficient strategy based on random structural color domains (SCDs) cellulose nanocrystal (CNC) proposed first time, combing with hyperspectral imaging system (HIS) ultrafast storage and authentication. By controlling growth fusion behavior...
In this work, Au nanoparticle (AuNP) arrays on shape memory polyurethane (SMPU) substrates serve as flexible materials for tunable localized surface plasmon resonance (LSPR). AuNP prepared by diblock copolymer self-assembly are transferred from rigid silicon wafers onto SMPU with ultrasonic treatment rather than peeling off directly. The resultant array films have excellent mechanical properties and stable thermodynamic properties. LSPR arising is increased negative bending substrates,...
A novel hybrid hydrogel system composed of CdTe QDs and SiO 2 PCs was developed for optical anti-counterfeiting information encoding–decoding.
Inspired by the formation of random sparkling microcrystallines in naturally precious opals, we develop a new strategy to produce class unclonable photonic crystal hydrogels (UPCHs) induced electrostatic interaction effect, which further achieve encoding/decoding and high-encrypted patterns along with an ultrahigh controllable encoding capacity up ca. 2 × 10166055. Owing randomness colloidal crystals self-assembly process, UPCHs randomly distributed spots are endowed...
Herein this study, plasmonic‐patterned nanostructures are applied to fabricate unclonable anti‐counterfeiting labels. Patterned Au nanoparticles (AuNPs) constructed by the skillful combination of diblock copolymer polystyrene‐block‐poly(4‐vinyl pyridine) (PS‐ b ‐P4VP) self‐assembly with shadow mask lithography provide a simple and universal approach for large‐area fabrication patterned nanostructures. The AuNP pattern can be made visible increasing nanoparticle size. A surface‐enhanced Raman...
Abstract Based on the irresistible inherent trade‐off between mechanical and self‐healing performances of cross‐linked polyurethane materials, there is still an intractable challenge to design efficient tough elastomers, especially in flexible sensors. Herein, a tough, self‐healing, recyclable elastomer (DTPU) was prepared by integrating oxime‐carbamate bonds thiourethane into network. The extraordinary properties DTPU elastomers were related synergistic effect main chain chemical sites....
