Abstract Light‐based 3D printing has received significant attention due to several advantages including high speed and resolution. Along with the development of new technologies, material design is key for next generation light‐based printing. Conventional printable polymeric materials, also known as photopolymers or photoresins, often lead thermosets–polymer networks cross‐linked by permanent covalent bonds which bring limited adaptability restricted reprocessability. Dynamic that can reversibly break reform enable network rearrangement, thereby offering unprecedented properties materials such adaptability, self‐healing, recycling capabilities. Hence, introducing dynamic into a promising strategy further expand meet diverse application scenarios printed multi‐functional moreover more demanding sustainable nature‐inspired considerations (e.g., self‐healing). Herein, an overview recent advances in printing, aiming bridge these two research fields presented. Importantly, current challenges are analyzed perspectives developing their potential applications provided.

Abstract The power of three-dimensional printing in designing personalized scaffolds with precise dimensions and properties is well-known. However, minimally invasive implantation complex still challenging. Here, we develop amphiphilic dynamic thermoset polyurethanes catering for multi-material four-dimensional to fabricate supportive body temperature-triggered shape memory water-triggered programmable deformation. Shape effect enables the two-dimensional printed pattern be fixed into temporary one-dimensional shape, facilitating transcatheter delivery. Upon implantation, temperature triggers recovery its original pattern. After swelling, hydrated undergoes morphing desired structure because swelling mismatch. exhibits unusual soft-to-stiff transition due water-driven microphase separation formed between hydrophilic hydrophobic chain segments. integration memory, deformability, swelling-stiffening makes developed promising void-filling scaffold materials implantation.

Hydrogels have emerged in various biomedical applications, including tissue engineering and medical devices, due to their ability imitate the natural extracellular matrix (ECM) of tissues. However, conventional static hydrogels lack dynamically respond changes surroundings withstand robust biophysical microenvironment trigger on-demand functionality such as drug release mechanical change. In contrast, multifunctional dynamic can adapt external stimuli drawn great attention recent studies. It is realized that integration nanomaterials into provides numerous functionalities for a variety applications cannot be achieved by hydrogels. This review article comprehensive overview advances designing fabricating applications. We describe different types based on breakable reversible covalent bonds well noncovalent interactions. These mechanisms are described detail useful reference crosslinking strategies strongly influence properties also discuss use potential benefits. further explores nanocomposite hydrogels, delivery, engineering, bioadhesives, wound healing, cancer treatment, mechanistic study, multiple-scale Finally, we challenges future perspectives field diverse technologies.

Shape memory and self-healing polymer nanocomposites have attracted considerable attention due to their modifiable properties promising applications. The incorporation of nanomaterials (polypyrrole, carboxyl methyl cellulose, carbon nanotubes, titania graphene, graphene oxide, mesoporous silica) into these polymers has significantly enhanced performance, opening up new avenues for diverse capability in depends on several factors, including heat, quadruple hydrogen bonding, π–π stacking, Diels–Alder reactions, metal–ligand coordination, which collectively govern the interactions within composite materials. Among possible interactions, only bonding between constituents been shown be effective facilitating at approximately room temperature. Conversely, thermo-responsive shape require elevated temperatures initiate healing recovery processes. Thermo-responsive (TRSMPs), light-actuated, magnetically actuated, Electrically actuated Memory Polymer Nanocomposite are discussed. This paper provides a comprehensive overview different types involved SMP SHP examines behavior both temperature conditions, along with biomedical many applications SMPs, special given (drug delivery, orthodontics, tissue engineering, orthopedics, endovascular surgery), aerospace (hinges, space deployable structures, morphing aircrafts), textile (breathable fabrics, reinforced electromagnetic interference shielding fabrics), sensor, electrical (triboelectric nanogenerators, information energy storage devices), electronic, paint coating, construction material (polymer cement composites)

The Diels–Alder (DA) reaction is a promising tool for obtaining covalently crosslinked hydrogels due to its bioorthogonality, the absence of by-products, and application mild conditions without catalyst. resulting are in demand use various fields materials science biomedicine. While dynamic nature cycloaddition diene dienophile has previously been used extensively fabrication self-healing materials, it only recently spread expansion functional properties polymer gels bioapplications. This review describes strategies recent examples based on DA reaction, demonstrating that emerging go beyond self-healing. types classifications listed, depending type components. Examples normal inverse electron-demand as well cell culture, drug delivery, injectable gels, wound dressings, considered. In conclusion, possible developmental directions discussed, including diene–dienophile pairs with low temperature reversal modification nanoparticles by and/or fragments, new applications such ink 3D printing, sensing hydrogels, etc.
