Abstract

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 R_a, R_z
ve R_max 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

Abstract

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.
