Web-Formation on Hydrophobic Substrates

G9 PAMAM on HOPG without Aggregates

HOPG, 10mm, pH~7, no LiCl

Web-formation: signature of loose surface bonding ?

Consistent with dragging effects in small scale scans

& with studies of dried films [Macromol. Symp. 167, 257 (2001)]

LiCl ("water structure breaker") has no effect

HOPG, 5mm, pH~7, 0.05M LiCl
