This project examines the arrays formed on various glass substrates using polymer solutions via the breath figure technique and were compared to find out whether a difference in number of carboxy group, weight % and substrate surface plays a part and how each variable alters the size and order of the pores. Solutions of Monocarboxy – Terminated Polystyrene (PSm) of 1% to 3% in weight in Carbon Disulfide (CS2) and Dicarboxy – Terminated Polystyrene (PSd) of 1% to 3% in weight dissolved in CS2 were used in this experiment. The arrays are formed on 3 different glass surfaces; namely normal microscope glass (soda lime glass), cleaned cover slip glass (borosilicate glass) and Indium Tin Oxide (ITO) coated conductive glass. From results of the varied factors, PSm, 1wt% on normal microscopic glass gives the best monodispersed arrays with longer range order. Conductive glass gives the smallest pore size while 1wt% gives the best degree of ordering.
