Effect of growth times on the physical and mechanical properties of hydrophobic and oleophilic silylated bacterial cellulose membranes
Bacterial cellulose is an extracellular natural byproduct of the metabolism of various bacteria. Its physical and mechanical properties were determined by growth period, method of cultivation either static or agitate, fermentation condition and medium.

Summary: | Bacterial cellulose is an extracellular natural byproduct of the metabolism of various bacteria. Its
physical and mechanical properties were determined by growth period, method of cultivation either static
or agitate, fermentation condition and medium. Thispaper presented works done on the effect of culture
time on the physical and mechanical properties of silylated bacteria cellulose membranes. Bacterial
cellulose (BC) growth under 4, 5, 6 and 7 days had been used as a natural reinforcement material and silane
as a hydrophobic coating material. With extended culture time, the tensile strength and tensile modulus
were increased linearly as result of more compact structure. Due to hydrophobic properties of silane, the
water absorption and thickness swelling improved correspondingly. Contact angle testingusing three
different liquid proven the functionality of silane as hydrophobic and oleophilic coating agent. The
experimental results suggested that hydropobicand oleophilicsilylatedbacteria cellulose membranes with
controlled growth time could be prepared and regarded as a reusable oil spills membrane. |
