EFFECT OF SILICA OBTAINED FROM RICE HUSK ON THE STRUCTURAL AND THERMAL PROPERTIES OF POLYLACTIC ACID/POLYETHYLENE GLYCOL FILMS
EFFECT OF SILICA OBTAINED FROM RICE HUSK ON THE STRUCTURAL AND THERMAL PROPERTIES OF POLYLACTIC ACID/POLYETHYLENE GLYCOL FILMS

BUĞÇE AYDIN [1] , FEZA Geyikçi [2]


Most of the plastic materials used in the packaging industry are petroleum-based. These plastics do not decompose in soil for many years and they lead to increase CO2 in the atmosphere. Biodegradable polymers derived from renewable resources such as polylactic acid (PLA) are considered as promising alternatives to petroleum-based polymers. Although PLA has attracted attention due to having properties such as biodegradable, environment friendly, and biocompatible, it cannot be used in many applications due to its poor gas barrier properties, low thermal stability, high brittleness, and cost. In this study, in the first step silica was obtained from the rice husk. The obtained silica (5,10 and 20%) were added to PLA solutions containing 20% polyethylene glycol (PEG) and the composite films were prepared using solvent casting method. The thermal and structural properties of the composite films were determined by Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscope (SEM), Thermogravimetric Analysis (TGA), Differential Scanning Calorimetry (DSC) and Water Absorption Capacity Test. According to results of analysis, the addition of silica to the PLA-PEG films improved the thermal stability and increased the water absorption capacities of films.

Ambalaj sektöründe kullanılan plastik malzemelerin çoğu petrol kökenlidir. Bu tür malzemeler doğada uzun yıllar çözünmeyip atmosferdeki CO2’in artmasına neden olur. Yenilenebilir kaynaklardan elde edilen polilaktik asit (PLA) benzeri biyobozunur polimerler petrol kökenli polimerlere alternatif olarak görülmektedir. PLA çevre dostu, biyobozunur ve biyouyumlu olması gibi birçok avantaja sahip olmasına rağmen düşük gaz bariyer özellikleri, termal dayanımı, kırılgan ve maliyetli olması birçok uygulamada kullanımını sınırlamaktadır. Bu çalışmada ilk olarak atık olarak görülen pirinç kabuğundan silika elde edilmiştir. Farklı katkı yüzdelerinde (%5, 10 ve 20) silika %20 polietilen glikol (PEG) içeren PLA çözeltilerine eklenmiş ve kompozit filmler çözücü döküm yöntemi ile hazırlanmıştır. Filmlerin termal ve yapısal özellikleri Fourier Dönüşümlü İnfrared Spektroskopi (FT-IR), Taramalı Elektron Mikroskobu (SEM), Termogravimetrik Analiz (TGA), Diferansiyel Taramalı Kalorimetre (DSC) ve Su Absorpsiyon Kapasitesi Testi ile belirlenmiştir. Analiz sonuçlarına göre, silikanın PLA-PEG filmlerinin termal dayanımını iyileştirdiği ve su tutma kapasitelerini artırdığı görülmüştür.
