“…These effects might be caused by interface incompatibility and a defective nanocomposite structure. Llorens et al 2012 reported similar defects in the distribution of silver zeolites in polylactide, together with voids growing around the permutate [ 35 ]. These results indicate that the composite antimicrobial particles were still acceptably well dispersed in the ethyl cellulose layer.…”

Porous adsorption, a less powerful adsorptive force than chemical bonds, is based on the physical adsorption of small molecules onto a solid surface that is capable of adsorbing gas or liquid molecules. Antimicrobial permutite composite (containing Ag+, Zn2+ and Ag+/Zn2+), starting from Linde Type A-permutite (LTA), was obtained in this research. The permutite samples were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), colorimeter and nitrogen adsorption technique. Cinnamon essential oil (CEO) was encapsulated into Ag+/Zn2+-permutite. The FT-IR and differential scanning calorimetry (DSC) confirmed that no chemical bond existed between CEO and Ag+/Zn2+-permutite. The loading capacity of Ag+/Zn2+-permutite/CEO was 313.07 µL/g, and it had a sustained release effect. The Ag+/Zn2+-permutite/CEO showed stronger efficacy against Aspergillus niger and Penicillium sp. than Ag+/Zn2+-permutite. Ethyl cellulose pads modified by composite antimicrobial particles were applied in the preservation of Chinese bayberry. Compared to the control group, treatment with the Ag+/Zn2+-permutite/CEO antimicrobial pads resulted in a significantly lower decay incidence. In addition, the amount of migrated silver, zinc and aluminum from LTA was below the legal limit. These results confirmed that the ethyl cellulose pads modified by the Ag+/Zn2+-permutite/CEO provided an active packaging to control decay of fresh Chinese bayberry.

“…또한 Ag의 단독 사용 뿐만 아니라 제올라이트 등에 함침 된 형태 [23][24][25][26][27]도 직물에 적용되고 있다. 은-제올라이트의 조합은 금속으로서의 은 원자 단독 사용시보다 더 뛰어난 향균성을 나타내고 열적 안전성도 훌륭하다 [28]. 그러나 그 메커니즘이 정확히 밝혀지지는 않았지만 항균성 발휘에 있 어서 용존산소가 반드시 필요하기 때문에 [27], 아웃도어와 같이 땀, 우천, 먼지로 인해 오염이 빈번한 적용분야에서는 항균력 발휘에 한계가 있다.…”

Polyurethane membrane was chosen as an alternate for Gore-Tex ® used in outdoor sportswear. Antimicrobial property was induced by dispersing titanium dioxide (TiO 2 ) particles on the surface of the membrane via sonication. Furthermore, Ag particle was photodeposited on the TiO 2 particles via UV irradiation to enhance the photocatalytic activity. Measurements using X-ray diffraction, scanning electron microscopy, and energy-dispersive X-ray spectroscopy showed that TiO 2 and Ag particles were evenly deposited on the membrane. In addition, the antimicrobial property against Klebsiella pneumoniae and Staphylococcus aureus was validated using the shake flask method and clear zone method.

In this study, a microfilter medium was prepared using a melt-blown system and used as a pre-filter in a reverse osmosis (RO) separation system. Asymmetric RO composite membranes, which are inorganic/organic-reverse osmosis (IPO-RO) membranes composed of polysulfone and polyamide with tourmaline nanoparticles, have been designed to develop a new desalination membrane showing high selectivity and permeability. The practical separation performance of IPO-RO composite membranes was investigated for the desalination of seawater, especially for deep ocean water. The separation characteristics of IPO-RO composite membranes were discussed by changing some parameters such as applied pressure and temperature. The permeation flux of the IPO-RO composite membranes was investigated using a module composed of RO plate-frame and spiral wound units. The solute rejection and flux for the IPO-RO composite membrane were 99.0-99.4% and 7.4-23.3 L/m 2 •h in deep ocean water at 20 o C, respectively. Further, the separation performance of the IPO-RO composite membrane for deep ocean water was very steady-state for a long time. Remarkably, the solution permeated through the IPO-RO composite membrane matched drinking water standards.
