INVESTIGATION OF THE POLYETHYLENE GLYCOL AND CHERRY STEM WASTE RATIOS ON THE FINAL THERMAL, AND MECHANICAL PROPERTIES OF POLYVINYL ALCOHOL BASED COMPOSITE FILMS

Abstract

“Green composites”, which are essentially composed of a biopolymer matrix and natural filler materials, have emerged as a significant alternative in the context of environmental pollution and sustainability studies in recent years. This study was designed to investigate the effects of polyethylene glycol (PEG) as a secondary polymer and cherry stem (CS) powder as a reinforcing phase on the thermal and mechanical performances of polyvinyl alcohol (PVA) based composite films. The composite films were produced using the solvent casting method. Taguchi optimization was performed to observe the effects of the PEG and CS ratios. The properties of the composite films were evaluated using Fourier transform infrared spectroscopy, thermogravimetric analysis, and mechanical testing. It was determined that the use of PEG improves the thermal properties due to its high thermal stability, as well as improving the elongation at break values, while decreasing tensile strength due to its plasticizing effect. CS generally improves thermal properties and tensile strength by up to 5% but decreases by 10% due to agglomeration. Elongation at break decreases as the amount of CS increases.

POLİETİLEN GLİKOL VE KİRAZ SAPI ATIK ORANLARININ POLİVİNİL ALKOL BAZLI KOMPOZİT FİLMLERİN NİHAİ TERMAL VE MEKANİK ÖZELLİKLERİ ÜZERİNE ETKİLERİNİN ARAŞTIRILMASI

Öz

Son yıllarda çevre kirliliği ve sürdürülebilirlik çalışmalarında önemli bir alternatif olarak görülen “Yeşil Kompozitler” temelde matris olarak biyopolimer ve takviye fazı olarak doğal bazlı dolgu malzemelerinden oluşan kompozit yapılardır. Bu çalışma, ikincil polimer olarak polietilen glikol (PEG) ve takviye fazı olarak kiraz sapı (CS) tozunun Polivinil alkol (PVA) bazlı kompozit filmlerin termal ve mekanik özellikleri üzerindeki etkilerini araştırmak amacıyla tasarlanmıştır. Kompozit filmler çözücü döküm yöntemiyle üretilmiş ve PEG ve CS oranlarının etkilerini gözlemlemek için Taguchi optimizasyonu gerçekleştirilmiştir. Kompozit filmlerin özelliklerini değerlendirmek için Fourier transform infrared spektroskopisi, termogravimetrik ve mekanik analizler yapılmıştır. PEG kullanımının yüksek termal kararlılığı nedeniyle termal özellikleri iyileştirdiği ve plastikleştirici etkisi nedeniyle gerilme mukavemetini azaltırken kopma uzaması değerlerini iyileştirdiği belirlenmiştir. CS kullanımı genel olarak %5 oranına kadar kadar termal özellikleri ve çekme dayanımı değerlerini iyileştirirken, %10 oranında aglomerasyondan kaynaklanabilecek bir düşüş meydana gelmekte ve CS miktarı arttıkça kopma uzaması değerleri düşmektedir.
