The deposition of "polydopamine" films, from an aqueous solution containing dopamine or other catecholamines, constitutes a new and versatile way to functionalize solid−liquid interfaces. Indeed such films can be deposited on almost all kinds materials. Their kinetics does not depend markedly the surface chemistry substrate, reach thickness few tens nanometers in single reaction step. Up now, even if lot is known about oxidation mechanism solution, only little information available describe...
Biodegradable and renewable UV-shielding films are highly demanded to meet the increasing sustainable requirement for environment. Lignin as a natural broad UV blocker has gained considerable attention; however, poor dispersibility within synthetic polymers limited its applications. Thus, bioinspired melanin-like polydopamine thin layer was incorporated first time with lignin nanoparticle (LNP) in this effort, forming UV-blocking core–shell lignin–melanin (LMNP) higher compatibility...
Renewable and biodegradable UV-blocking films are in high demand for the increasing need of sustainable environment. Lignin can offer significant UV absorption, but it deteriorates mechanical properties at a content. In this effort, biobased 10-undecenoic oleic acids were successfully grafted on soda lignin via solvent- catalyst-free processes, as confirmed by 31P 1H NMR Fourier transform infrared (FTIR). The resulting ester derivatives neat then melt-blended with poly(butylene...
Eumelanin is a ubiquitous pigment in nature and has many intriguing physicochemical properties, such as broad-band monotonous absorption spectrum, antioxidant free radical scavenging behavior, strong nonradiative relaxation of photoexcited electronic states. These properties are highly related to its structural mechanical make eumelanin fascinating candidate for the design multifunctional nanomaterials. Here we report joint experimental-computational investigation assemblies produced from...
The present paper relies on the original idea to design multifunctional coatings, and in particular highly efficient intumescent flame retardant based diffusion of polyphosphates (PSPs) exponentially growing "layer-by-layer" films made from montmorillonite (MMT) poly(allylamine) (PAH). Here, we used as an acid source, polyallylamine both a carbon source swelling agent, finally clays reinforce char strength also for their oxygen barrier property. coatings alternated deposition n = 60 layer...
We report on the growth by evaporation under high vacuum of high-quality thin films Fe(phen)2(NCS)2 (phen=1,10-phenanthroline) that maintain expected electronic structure down to a thickness 10 nm and exhibit temperature-driven spin transition. have investigated current-voltage characteristics device based such films. From space charge-limited current regime, we deduce mobility 6.5×10−6 cm2/V s is similar low-range measured widely studied tris(8-hydroxyquinoline)aluminum organic...
The modification of solid-liquid interfaces with polyelectrolyte multilayer films appears as a versatile tool to confer new functionalities surfaces in environmentally friendly conditions. Indeed such are deposited by alternate dipping the substrates aqueous solutions containing interacting species or spraying these on surface substrate. Spin coating is more and used produce similar films. aim this short review article provide an unifying picture about deposition mechanisms Often those...
Eumelanin is not only a ubiquitous pigment among living organisms with photoprotective and antioxidant functions, but also the subject of intense interest in materials science due to its photoconductivity as possible universal coating platform, known "polydopamine films". The structure eumelanin remains largely elusive, relying either on polymeric model or heterogeneous aggregate structure. well that closely related films" can be modified by playing nature oxidant used oxidize dopamine...
Four-dimensional (4D) printing technology, as a next-generation additive manufacturing method, enables printed objects to further change their shapes, functionalities, or properties upon exposure external stimuli. The 4D of programmable and deformable materials such thermo-responsive shape-memory polymers (trSMPs), which possess the ability shape by heat, has attracted particular interest in recent years. Three-dimensional based on SMPs have been proposed for various potential applications...
