크롬 기반 금속유기골격체(MIL-101(Cr))를 제조하고 이들을 활용한 유사화학작용제 diisopropyl methyl phosphonate(DIMP) 흡착 실험을 통해 방독면 정화통이나 보호의 충진물질로서 활용 가능성을 평가하였다. MIL-101(Cr)은 조절인자로 아세트산(MIL-101(Cr)-A)과 수산화나트륨(MIL-101(Cr)-N)을 활용하여 각각 제작하였는데, 아세트산을 조절인자로 사용하였을 때 보다 넓은 비표면적과 높은 DIMP 흡착량을 보였다. MIL-101(Cr)-A는 상대습도 90% 환경에서 10일 동안 노출 시 흡착제 무게 대비 약 160%의 수분을 흡수하여 활성탄 등 다른 흡착제와 비교할 때 흡수율이 높았다. MIL-101(Cr)-A를 상대습도 90% 환경에서 일정기간 노출한 시료에 대한 DIMP 흡착량 실험 결과 24시간 이후에는 노출되지 않았을 때 흡착량의 약 40% 수준으로 감소하였으나, 이 흡착량은 상용 방독면 정화통 충진 활성탄과 비교하였을 때 여전히 높은 흡착량으로 추후 방독면 정화통이나 보호의 충진물질로서 활용가능성이 높은 것으로 판단된다.

Cow leather coated with polyurethane film that contains various organic photosensitizers was investigated to demonstrate the antimicrobial properties in the application of the material to protective clothing and home appliances. To prepare the antimicrobial coating on leather surfaces with high potency against microbes, photoactive agents, such as benzophenone (BP), 4,4'-bis(dimethylamino) benzophenone (MK), 4,4'-dihydroxybenzophenone (DHBP) and methylene blue (MB), were incorporated into polyurethane-based coating solutions. The photoactive antimicrobial agent treated leather samples were characterized by SEM, color appearance, color fastness against abrasion, and antimicrobial tests. The optical properties of organic photosensitizers indicated that active UV absorbance ranges were different: BP (around 250 nm), MK (around 360 nm), DHBP (around 305 nm) and MB (around 295 nm &570 nm-685 nm). The intensity of the UV absorbance curve at the UVA light wavelength for the antimicrobial test showed the highest value with MK; subsequently, this was followed by MB, DHBP and BP in decreasing order. The treated-leather samples demonstrated excellent antibacterial activity under UVA light. The antimicrobial effects for the Staphylococcus aureus were superior to Escherichia coli. Moreover, the polyurethane finishing showed an effective durability to abrasion. The overall results indicated that DHBP is the most suitable PU coating additive to provide antimicrobial properties to leather as well as color and surface appearance than MK, MB, and BP.
