Abstract:
A waterborne shape memory polymer coating that gives textiles and fibers good shape memory performance. An amphiphilic, crosslinkable grafted polysaccharide polymer was synthesized and provided in a water dispersion that can be applied to a flexible fibrous material and then crosslinked to yield good shape memory properties. The polymer coating showed good binding to human hair, which could be styled into a permanent shape (e.g., straight) during the crosslinked step. Next, this permanent shape can be styled to a temporary shape (e.g. curly) by heating and styling, and cooling. Finally, the permanent style can be regained by activation with water, heat, or both.
Abstract:
A coating agent composition of the present invention contains photocatalyst particles composed of metal oxide in which an upper end potential of a valence band is 3 V (vs SHE) or more and a lower end potential of a conduction band is 0.16 V (vs SHE) or less. Moreover, the coating agent composition contains cuprous oxide particles, metal oxide particles without photocatalytic activity, a binder resin, and an organic solvent. Then, in 100 parts by mass of a non-volatile matter content of the coating agent composition, a content of the photocatalyst particles is 1 to 80 parts by mass, a content of the cuprous oxide particles is 0.1 to 5 parts by mass, and a total content of the photocatalyst particles and the metal oxide particles is 40 to 80 parts by mass.

Abstract:
Coating compositions contain hydroxyl- or carbamate functional resins with a relatively low equivalent weight. The resins are based on a polyol core containing urea and hydroxyl groups, and made by reacting a polyisocyanate, preferably a triisocyanate, with an amino functional polyol, preferably a polyol having one amino group and two or more hydroxyl groups. The polyol core may be further extended to a first or higher generation dendrimer or hyperbranched structure by reacting the initial polyol core with a compound having one carboxyl group and two or more hydroxyl groups.
