Farklı Biyokütlelerden Elde Edilen Nişasta İle Akıllı Biyoplastik Malzeme ve Odun Biyoplastik Kompozit Üretimi

Bu çalışmanın amacı, petrol türevi ambalajların insan sağlığına ve çevreye verdiği zararı en aza indirebilmek için farklı biyokütlelerden elde edilen nişasta esaslı çevre dostu alternatif akıllı biyoplastik ve odun biyokompozit ambalaj malzemelerinin üretilmesidir. Bu amaçla, üretilen numunelerin sudaki çözünme (%), su alma (%), ASTM D 792 standartlarına göre yoğunluk (g/cm3) ve ISO 4287 standardına göre yüzey pürüzlülüğü değerleri belirlenmiştir. Elde edilen sonuçlara göre; en yüksek ve en düşük suda çözünme değerleri sırasıyla % 100 ile D numunesi ve % 8,01 ile F numuneleridir. Suda alma (%) değerleri, en yüksek % 242 ile B numunesi en düşük ise % 108 değeri ile E numunesi ölçülmüştür. En düzgün yüzeye Ra, Rz ve Rmax değerleri ile sırasıyla, 3.53, 18.8 ve 25.1 µm olarak A numunesi ölçülür iken, yüzey pürüzlülüğünün en fazla olduğu numune ise 10.4, 43.8 ve 55.0 µm değerleri ile D numunesinin olduğu belirlenmiştir.

Production of Bioplastic Composite and Wood Bioplastic Composite with Starch from Different Biomasses

The aim of this study is to produce eco-friendly alternative bioplastic and wood biocomposite packaging materials based on starch, derived from different biomasses, in order to minimize the damage caused by petroleum derivative packages to human health and the environment. For this purpose, solubility in water (%), water absorption (%), density according to ASTM D 792 (g/cm3) and surface roughness values according to ISO 4287 standard were determined. According to the results obtained; the highest and lowest water solubility values are sample D with 100 % and sample F with 8.01 %, respectively. The highest and lowest water absorption (%) capacity with value of % 242 as sample B and as 108 % with the sample E were measured respectively. The most uniform surface was obtained by the values Ra, Rz and Rmax, as 3.53, 18.8 and 25.1 µm for sample A while the highest surface roughness with respectively as 10.4, 43.8 and 55.0 µm values for sample D was determined.
