Multifunctional polymer nanocomposite coated antibacterial filters for air-purification

Öz

Products used and produced in industrial locations must have natural ingredients and minimal energy usage due to air and environmental pollution. It is impossible for standard filters to clean bacterias in homes, workplaces and areas working with biological creatures. Therefore, the production of multifunctional nanocomposite and hybrid filter papers is necessary. In the study, filter papers coated with nanocomposite solutions prepared from green synthesized nanosilver (AgNPs) with plant extracts and Polyvinyl Alcohol (PVA). Scanning Electron Microscope (SEM) analyses showed that silver nanoparticles and PVA homogeneously coated the filter paper fibers, thereby reducing the average pore diameters by only 3% compared to commercial standards of filter paper. A filter with 36% higher burst pressure resistance was produced by nanosilver, plant extracts and PVA modification. The antibacterial effect is provided to the filters with a high effect of up to 10000 times, by coating them with nanosilver and plant extracts. This study made it possible to produce filter paper with natural ingredients and at low cost, reducing energy and raw material consumption, with high antibacterial effect and mechanical strength. In this way, bacteria and pollutants in the air will be cleaned without harming the environment and human health.

Hava temizleme için çok fonksiyonlu polimer nanokompozit kaplamalı antibakteriyel filtreler

Öz

Hava ve çevre kirliliği, endüstriyel alanlarda kullanılan ve üretilen ürünlerin doğal içerikli ve düşük enerji tüketimine sahip olmasını gerektirmektedir. Evlerde, işyerlerinde ve biyolojik canlılarla çalışılan alanlarda standart olarak kullanılan filtrelerin bakterileri temizlemesi mümkün değildir. Bu nedenle çok fonksiyonlu kompozit ve hibrit filtre kağıtlarının üretimi gerekmektedir. Çalışmada yeşil sentezlenmiş nanogümüş (AgNPs), bitki ekstraktları ve Polivinil Alkol (PVA) ile hazırlanan nanokompozit solüsyonlarla kaplanmış filtre kağıtları kullanıldı. Taramalı Elektron Mikroskobu (SEM) analizleri, gümüş nanopartiküllerin ve PVA'nın filtre kağıdı elyaflarını homojen bir şekilde kapladığını, böylece ortalama gözenek çaplarını, filtre kağıdının ticari standartlarına kıyasla yalnızca %3 oranında azalttığını gösterdi. Nanogümüş, bitki özleri ve PVA kullanılarak %36 daha yüksek patlama basıncı direncine sahip bir filtre üretildi. Filtreler nanogümüş ve bitki özleri ile kaplanarak 100.000 kata kadar yüksek etki ile antibakteriyel etki sağlanmaktadır. Bu çalışma, doğal içerikli, düşük enerji ve hammadde tüketimine sahip, düşük maliyetli, antibakteriyel ve mekanik mukavemeti yüksek filtre kağıdı üretimine olanak sağladı. Bu sayede hava ortamındaki bakteri ve kirleticiler çevreye ve aynı zamanda insan sağlığına zarar vermeden temizlenmiş olacaktır.
