000 weight average molecular weight in eg were also degassed with nitrogen for then 20 ml syringes of each were prepared the agno 3 and pvp solutions were then added at a constant rate over 25 min via a 12 gauge a teflon u00ae fluoropolymer syringe needle the flask was then held at temperature for 120 min after which it was allowed to cool down to ambient temperature fig1 shows an optical micrograph of the silver nanowire product which had an average nanowire length of 28 2 u00b1 10 4 u03bcm and an average nanowire diameter of 56 1 u00b1 13 7 nm based upon measurement of at least 100 wires into a 500 ml reaction flask was added 290 ml propylene glycol pg and 4 4 g polyvinylpyrrolidinone pvp 55 000 weight average molecular weight the headspace of the flask was blanketed with nitrogen at approximately 0 5 l min and was heated to 110 u00b0 c while being stirred 12 0 ml of 1 0 m agno 3 in pg and 10 0 ml of 42 mm lithium chloride in pg were added to the flask each at a constant rate of 0 5 l min with the addition of the lithium chloride solution being delayed until 4 0 min after initiating the agno 3 solution feed immediately after completing feeding the agno 3.
