“…For instance, invisible patterns could be revealed by different swelling capabilities of crosslinked regions of the opal structure . As another example, Wu et al reported a reversible solvatochromic‐responsive behavior of ordered soft hydrophilic polymer spheres when the opal films were treated with water . It has to be mentioned that according to the Bragg equation given in Section , both the swelling capability of the opal structure, which causes a change of the lattice planes, and the refractive index of the “detected” solvent have to be taken into account for understanding the optical properties of the opal films.…”

“…[61] As another example, Wu et al reported a reversible solvatochromic-responsive behavior of ordered soft hydrophilic polymer spheres when the opal films were treated with water. [67,68] It has to be mentioned that according to the Bragg equation given in Section 1.1, both the swelling capability of the opal structure, which causes a change of the lattice planes, and the refractive index of the "detected" solvent have to be taken into account for understanding the optical properties of the opal films. Another general strategy for the enhancement of the mechanical robustness of soft opal films is the use of a substrate, e.g., glass, silicon wafers or additional polymer films or films that can be photo-crosslinked.…”

Photonic band-gap materials attract enormous attention as potential candidates for a steadily increasing variety of applications. Based on the preparation of easily scalable monodisperse colloids, such optically attractive photonic materials can be prepared by an inexpensive and convenient bottom-up process. Artificial polymer opals can be prepared by shear-induced assembly of core/shell particles, yielding reversibly stretch-tunable materials with intriguing structural colors. This feature article highlights recent developments of core/shell particle design and shear-induced opal formation with focus on the combination of hard and soft materials as well as crosslinking strategies. Structure formation of opal materials relies on both the tailored core/shell architecture and the parameters for polymer processing. The emphasis of this feature article is on elucidating the particle design and incorporation of addressable moieties, i.e., stimuli-responsive polymers as well as elaborated crosslinking strategies for the preparation of smart (inverse) opal films, inorganic/organic opals, and ceramic precursors by shear-induced ordering.

“…For example, Wu et al reported a reversible solvatochromic-responsive behavior of ordered soft hydrophilic polymer spheres when treated with water. 32,33 A crystalline colloidal array of hydrogel-based photonic crystals has been applied as a sensor showing distinct diffraction color changes when treated with different transition metal cations or after changing the pH. 34 Moreover, elastomeric polymer-based opals with a soft, slightly crosslinked matrix yielded reversible stretch-tunable films that showed remarkable color changes due to a bend or stretch modification of the 111 (200) plane spacing.…”

Reversible Light-, Thermo-, and Mechano-Responsive Elastomeric Polymer Opal Films

et al. 2013

A new strategy to achieve easily scalable triple stimuli-responsive elastomeric opal films for applications as stretch-tunable photonic band gap materials is reported. Novel monodisperse highly functional core-interlayer-shell beads are obtained by semicontinuous emulsion polymerization featuring a temperature-sensitive fluorescent rhodamine dye either locally restricted in the core or the shell of prepared beads. After extrusion and compression molding, homogeneous elastomeric opal films with fascinating stretch-tunable and temperature-dependent fluorescent properties can be obtained. Applying strains of only a few percent lead to significant blue shift of the reflected colors making these films excellent candidates for applications as deformation sensors. Higher strains up to 90% lead to a tremendous Bragg reflection color change caused by transition from the (111) to the (200) lattice plane. The well-ordered opaline structure with its stop band at the emission frequency of the incorporated fluorescent dye shows remarkable angle-dependent fluorescence suppression. Herein described elastomeric opal films can be valuable in a wide range of applications such as rewritable 3D optical data storage, tunable laser action, and sensing materials.

“…As renewable resources, wood has great potential in furniture and decoration materials that can take the place of steel, stone, and glass, due to the forthcoming exhaustion of un-renewable resources, such as petroleum, coal, and minerals [41][42][43]. However, as a natural hygroscopic polymer composite with many hydrophilic groups such as hydroxyl groups (-OH), wood is apt to absorb water, which would result in dimension instability and microorganism attacks from decay fungi or mold.…”

Fabrication of Self-healing Superhydrophobic Surfaces from Water-Soluble Polymer Suspensions Free of Inorganic Particles through Polymer Thermal Reconstruction

Self-healing superhydrophobic surfaces have been fabricated by casting and drying water-soluble amphiphilic polymer suspensions at room temperature through thermal reconstruction. When compared with previous methods, this approach exploits modified natural hierarchical microstructures from wood instead of artificially constructing them for superhydrophobic morphology, which involves neither organic solvent nor inorganic particles nor complex procedures. The obtained superhydrophobic surface has acceptable resistance to abrasion. The surface can recover superhydrophobicity spontaneously at room temperature upon damage, which can be accelerated at a higher temperature. After depleting healing agents, the polymer suspension can be sprayed or cast onto wood surfaces to replenish healing agents and to restore self-healing ability. The superhydrophobic surface greatly increases the mold inhibition and water resistance of wood, which would prolong the service life of wood based materials.
