Microtubes, fabrication

Nanowalled polymer microtubes fabricated by using strained semiconductor templates. Nanotechnology 2010,27, 245305/1-245305/5. 

The microfluidic chip system for preparing a miniaturized PMBV/PVA hydrogel consists of a two-chamber chip, an aluminum custom-made chip holder, Teflon capillaries, microtubes, and syringes equipped with a microsyringe pump (Fig. 15). The two-chamber chip was fabricated by a photolithographic wet etching technique. Whereas both channels and chambers (200 pm in depth) were fabricated on the top plate, only chambers (200 pm in depth) were fabricated on the bottom plate.

First of all, the forerunning work was performed with electrochemical polymerization of PANI micro- and nanorod fabrication [173,174]. Iridium and platinum needles were used as electrodes, and a PANI microrod was grown on the electrode surface. Another approach was related to the ful-lerene derivatives doping with electrochemical polymerization in order to fabricate PANI microfibers and nanofibers [175,176]. hi addition, PPy microtubes have been synthesized in the presence of S-naphthalene sulphonic acid (jd-NSA) by electrochemical polymerization. This microtube has the diameter of 0.8-2.0 xm and the length of 15-30 im. Electrochemical deposition of PANI has been also carried out within multi-walled CNT. hi addition, PPy microtube (a few mm in length and hundreds xm in diameter) is formed in the presence of Na-toluene sulphonic acid along platinum wire [177]. 

PANI micro- and nanotubes have been prepared by chemical polymerization using fullerene, NSA derivative, and azobenzene sulphonic acid [178, 179]. PPy microfiber and microtube were also fabricated in the presence of jd-NSA and the morphology of conducting polymer could be tuned by controlling the concentration of /3-NSA [101].
