“…This key property of optically clear polymers is intrinsically related to their molecular structure, their chain conformation, and the presence of impurities in the formulation. In the presented systems, besides the judicious choice of precursors bearing no chromophore species capable of absorbing light in the visible range (namely, the functional polyacrylates and the aliphatic bismaleimides), transparency can be attributed to the completely amorphous nature of the developed DA‐based polymeric networks. Moreover, differently from other dynamic covalent networks recently reported, systems based on the DA chemistry do not require catalysts, which could cause unwanted coloring of the resulting solid material…”

the development of approaches based on disulfide bond exchange, [3] alkoxyamine dissociation, [4] thiol-Michael reaction, [5] Alder-ene addition, [6] and bulky urea bonds, [7] the most widely reported systems are based on the well-established Diels-Alder (DA) cycloaddition. [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] DA is a click-type addition reaction between a dienophile and a diene, typically a maleimide and a furan. The design of a polymer network where crosslinks are constituted by DA adducts would result in the ability to cleave the crosslinks at mildto-high temperature through a retro Diels-Alder process (r-DA), while enabling their reformation upon cooling through the direct DA reaction. Therefore, the r-DA/ DA sequence can be exploited to repair cracks or to remold the crosslinked material. [24] The concept, firstly described in a patent [25] and then in the milestone work of Wudl [26] has been exploited for the dynamic crosslinking of different polymer matrices like epoxies, [27,28] elastomers, [29,30] polyesters, [31,32] and polyketones. [33,34] A straightforward strategy to design DA crosslinked acrylates is based on the combination of linear copolymers of furfuryl methacrylates (FMAs) with difunctional maleimide linkers. [8][9][10]12,16,20] The reported systems are typically characterized by high healing efficiency. However, they lack in transparency and usually exhibit a yellow-to-orange color, predominantly due to the use of aromatic bismaleimide linkers. This feature factually forbids the utilization of DA-based acrylates for optical applications, where high levels of transmittance in the visible wavelength range are inevitably required.To bridge this gap, a straightforward strategy to prepare colorless and transparent thermoresponsive acrylates based on the DA chemistry is proposed in this work. Furan functional polyacrylates were synthetized via free radical polymerization of FMA with methacrylates bearing different aliphatic groups. Two aliphatic bismaleimides, with different chain length, were synthesized starting from the respective diamines. The obtained linear copolymers containing furan moieties were combined with the bismaleimides in solvent, and colorless, high-transmittance, crosslinked coatings were obtained. The thermal reversibility of the DA-coatings was assessed by means of differential scanning calorimetry (DSC) and solubility experiments. After assessing the self-healing ability of the acrylicbased polymeric materials, the effect of network structure (i.e.,

“…Another PU antierosion coating, proposed by Fraunhofer Institute IFAM, includes curable composition including aliphatic diisocyanate, cycloaliphatic diisocyanate, and polyether polyol . In previous studies, it is suggested to add Diels‐Alder additives (ionomeric coatings) to improve rheology and enhanced viscosity of coatings and the clay addition to improve impingement.…”

Factors and structural parameters of coatings influencing the efficiency of protective coating systems against rain erosion of wind turbine blades are reviewed. The possibilities to enhance the attenuation of wave energy from droplet impact, increase damping and varying stiffness, creating interfaces for wave reflection, adding reinforcement for wave scattering, and creating additional layers or skeleton‐like reinforcing or wave absorbing structures, are discussed in the paper. Formulas for quantitative estimation of these effects as well as qualitative relationships between the structural parameters of coatings and their performance are presented. Recommendations and promising directions for the improvement of the protective coating systems for rain erosion protection of wind turbine blades are presented.

Circular and Flexible Indoor Partitioning—A Design Conceptualization of Innovative Materials and Value Chains

2019

View full text Add to dashboard Cite

This article sheds light on the materialization and operation of residential partitioning wall components in relation to circular and flexible performance. The hypothesis is twofold: (1) A stronger integration of materialization and operation aspects is indispensable in establishing sustainable value-models, and (2) recent innovations, concerning the reversibility of material connections, will help disrupting the status-quo in that respect. Attention is drawn to renewable natural fibre composites (NFC), reversible adhesives, and biodegradable insulation materials. After a background sketch regarding the notion of time, change, and material circularity in design and planning, the housing challenge in the Amsterdam metropolitan area (AMA, the Netherlands) is described. Next, a design conceptualization stage is introduced, informed by two methods and tools in particular: Circ-Flex assessment, and activity-based spatial material flow analysis. Results of the conceptualization stage are presented regarding materialization and operation, culminating in Circ-Flex partitioning components, more specifically: Side panels and insulation. It was found that NFC can tackle current issues relating, most prominently, to circularity performance. Associated modifications in the value-chain occur, above all, in raw material sourcing, manufacturing, reutilization logistics, and data-sharing. The outcomes are valid for multiple building components other than indoor partitioning, such as kitchens and furniture, but also insulation—and interior side-sheeting—of walls and roofs in energy-renovations.
