https://www.selleckchem.com/products/triptolide.html A carbohydrate-based fullerene derivative (AcMal7-C61) is designed, synthesized and applied to a lamellar-forming high-χ block copolymer system, poly(3-hexylthiophene)-block-peracetylated maltoheptaose (P3HT-b-AcMal7), to actualize an ordered donor/acceptor (D/A) network. A well-defined D/A lamellar structure of the P3HT-b-AcMal7AcMal7-C61 blend with sub-10 nm domain features is achieved upon thermal annealing. The AcMal7-C61 molecules are localized in the phase-separated AcMal7 nanodomains without causing the formation of fullerene crystals while maintaining the lamellar morphology up to 10.5 (DA) blending ratio. The cross-sectional TEM observation and GISAXS measurement reveals that the P3HT-b-AcMal7 tends to spontaneously organize into lamellar structures oriented perpendicular to the film surface at the air/film interface while the domain orientation at the bottom interface depends on the nature of the substrate.In this work deep eutectic solvent (DES), based on the mixture of choline chloride and lactic acid, were suggested as chitosan films plasticizers. The molecular structure and properties of films obtained using chitosan, with different degree of deacetylation and 0-80 wt.% DES content (ωDES), were studied by means of FTIR spectroscopy, SEM and AFM microscopy (films' surface properties) together with optical characteristics, water vapor transmission rate (WVTR), water vapor permeability (WVP), tensile strength (TS) and elongation at break (Eb). Scanning electron micrographs revealed that all chitosan-DES films were smooth and uniform. DES significantly improves the film flexibility (Eb increases of ca. 160 % after incorporation of 80 wt.% DES), slightly decreases tensile strength and also improves antioxidative properties while simultaneously, increasing water vapor permeability (WVP). Films prepared in this study exhibit characteristics that qualify them for potential use as an active packaging material
