Method for fabricating polymethylmethacrylate micro-nanotube arrays based on spin-coating method and PAA templates

A novel and low-cost method for fabricating poly(methyl methacrylate) micronanotube arrays (PMMA-MNAs) using a porous anodic aluminium (PAA) template and spin-coating method was presented. PMMA-MNAs with different length micronanotubes were fabricated by changing the temperature of electric heating...

Description
Summary:A novel and low-cost method for fabricating poly(methyl methacrylate) micronanotube arrays (PMMA-MNAs) using a porous anodic aluminium (PAA) template and spin-coating method was presented. PMMA-MNAs with different length micronanotubes were fabricated by changing the temperature of electric heating drying oven and heating time, then characterised by field-emission scanning electron microscope. Experimental results showed that the poly(methyl methacrylate) (PMMA) liquid membrane was obtained by means of spin coating at the spin velocity of 4000 r/min, and can further grow into PMMA-MNAs using an all-through-pore PAA film as template at a certain temperature. The length of PMMA-MNAs increased nonlinearly with the increasing of the oven temperature and trended to a stable value (about 6.51 μm) at 150°C for 1.5 h. Flexible PMMA-MNAs with characteristics of hollow structure will have wide application prospects in catalyst carrier, high precise sensor, drug sustained release and so on. The presented experimental results could facilitate understanding the growth mechanism of polymer nanotube arrays.
