Abstract Details

2016, Master of Science in Polymer Engineering, University of Akron, Polymer Science.
Spider’s viscid silk glue is made of several natural materials such as glycoproteins, salts and water. By tuning the viscosity with humidity, spider glue can show good adhesion especially in high humidity condition. A lot of work has been done to understand the change in glue bulk properties of humidity response, but the effect of surface properties on glue adhesion is not well understood. In nature, many insects have electrostatic charge on their surface. And most of the insects have hydrophobic surface. To find out how the electrostatic charge and surface energy influence adhesion, we studied the adhesion on charged surface and hydrophobic surface using NanoBionix. The spreading on the charged surface is analyzed using high speed camera video. We find that charge can help in bringing the silk in contact but spreading is not enhanced by charge after the contact. And the adhesion tests on the charged surface and 0V potential surface show similar result. By comparing the different adhesion on hydrophilic surface and hydrophobic surface, we find spider silk glue shows better adhesion on hydrophobic surface than on hydrophilic surface.
