Polimer içerikli malzemeler, doğal ya da sentetik yapıdaki polimerler ile hazırlanan, nanometre boyutunda analiz edilebilen matris sistemlerdir. Nanoölçek seviyesinde yapılar içeren malzemelerin özellikleri makroskopik ölçekten tamamen farklıdır. Nano boyuttaki malzemenin iletim özellikleri (momentum, enerji ve kütle), optik, elektronik, manyetik ve kimyasal özellikleri değişir. Polimerlere kil katkısı ile polimer/kil nanokompozitler elde edilir ve çeşitli spektroskopik yöntemler kullanılarak polimer/kil nanokompozitlerin termal, mekanik ve yüzey karakterizasyonu yapılabilmektedir. Bu çalışmada, yüzey analiz metotlarında kullanılan İnfrared Spektroskopisi (FTIR), X-Işınları Kırınım Yöntemi (XRD), Taramalı Elektron Mikroskobu (SEM), Geçirimli Elektron Mikroskobu (TEM), Atomik Kuvvet Mikroskobu (AFM) hakkında bilgi verilmiştir.

“…The band at 3419 cm -1 along with weak band around 1619 and 1637 cm -1 are attributed to the stretching vibrations of the free hydroxyl group these may due to moisture accompanied with the sample. 19 32 The XRD patterns for the membranes before and after MB adsorption are shown in Figure 7. The main peaks for the clay appear at 2θ = 20.89° and 26.65° as displayed in Figure 7a.…”

“…Large ratio of surface area to volume or fine particles gives clay minerals a set of unique adsorption properties for various organic dyes, metals or other environmental pollutants. [18][19][20] Furthermore, adsorption using inexpensive and affordable adsorbent would make removal of different dyes or metal pollutants from wastewater feasible. The abundance of natural clay minerals in a low cost permits them to become a strong candidate as an adsorbent for getting rid of toxins from wastewater.…”

Water pollution is a serious environmental problem. Methylene blue is among the dyes that may exist in waste water. Adsorption is an effective process to remove dyes from contaminated water. Hybrid membranes based on clay-polymer; namely kaolin and polystyrene were prepared to absorb the present methylene blue in aqueous solution. These membranes were fired at 1000 °C to degrade polystyrene leaving cavities in the clay matrix with an expanded surface area and porous structure. The membranes were characterized via X-ray diffraction and Infrared spectroscopy. The morphological structure was investigated by using scanning electron microscopy. In this work, we are focusing on facile means represented in UV-Vis spectroscopy, to monitor the adsorption efficiency of the prepared membranes. From the results, the membrane loaded with 20% polystyrene by weight showed the optimum performance in adsorbing methylene blue from water.
