Fabrication of deodorizing fabric by grafting of metal phthalocyanine derivative onto nonwoven polypropylene fabric

Abstract

ABSTRACT:The premelting behavior of bacterially synthesized polyester poly(3-hydroxybutyrate-co-3-hydroxyhexanoate), abbreviated as P(HB-co-HHx), was investigated by two-dimensional Fourier-transform infrared (2D FTIR) correlation spectroscopy. The temperature-dependent dynamic spectra were measured over a temperature range of 25-300°C. We focused our study on the thermally induced intensity fluctuations of bands for CAO (1700 -1760 cm Ϫ1 ), COH (2910 -3010 cm Ϫ1 ) and COOOC groups (1220 -1310 cm Ϫ1 ) stretching vibrations. Changes of crystalline conformation due to the thermal perturbation could be detected by the intensity and location variations of those characteristic bands responding to the variations of dipole moments. 2D correlation analysis indicated that the appearance of fully amorphous component did not happen simultaneously with the disappearance of crystalline component, suggesting that there was an intermediate state between ordered crystalline and amorphous states in P(HB-co-HHx).

Singlet oxygen generation properties of Fe-OCAP and its influence on the antibacterial and mechanical properties of Fe-OCAP/PU blends

“…Researchers mainly paid their attention to studying the photosensitized oxidation procedure of Pc itself. Only a few studies involved the role of Pc playing in a Pc/polymer blend [1,4,6]. Mosinger et al [1] prepared a photofunctional PU nanofabrics doped by ZnPc.…”

“…Pc has been a group of promising second generation photosensitizers [4][5][6][7][8][9][10]. The mechanism of the photosensitized oxidation reactions of Pc has been widely investigated.…”

Preparation and characterization of Fe‐Tetranitro phthalocyanine/polyurethane blends

“…Recently, as a group of promising photosensitizers, phthalocyanine (Pc), and its derivatives were given special attention due to their strong absorption in the visible region of the spectrum, high efficiency in bacterial inactivation, ease of chemical modification and formulation and extraordinary stability . Researchers mainly concerned the antibacterial properties of Pc itself.…”

Effect of Weave Geometry on Surface Energy Modification of Textile Materials via Atomic Layer Deposition

“…Several physical and chemical means have been utilized to modify three-dimensional fibrous networks, including evaporative coating [9,10], chemical vapor deposition [9], sol-gel processing [11], spin-on glass incorporation [9][10][11], as well as ozone, plasmavapor and ultraviolet photon exposure [12][13][14][15][16]. Vapor phase processes, including atmospheric pressure plasma exposure, are currently scaled to the rates required for high throughput processing, however, they often suffer from non-uniform surface modification due to line of sight and precursor delivery limitations, or low density of surface charge sites [17][18][19][20][21]. Atomic layer deposition represents a realistic alternative to these methods of nanoscale surface modifications.…”
