Another way of producing layered structures has been brought to my attention and a summary of it can be found at (http://www.ces.clemson.edu/mmpl/concepts/Tutorial/tutorial.html), a Clemson...… Read More

We’ve been discussing the formation of nanolayers using layer generators as described in several patents to Dow chemical and showing the impact of these layers on barrier and optical...… Read More

Earlier I discussed the need for outer lubricating layers when forming micro or nanolayer coextrusions. This is discussed in US Patent 5,269,995 where the causes of the layer breakup are said to...… Read More

I received this question by e-mail and thought it might be interesting to a wide range of readers. So, I will take a short break from nanolayer technology to put it here. Question: Dear Dr....… Read More

It would seem to me that as film layers get thinner and thinner when coextruding into nanolayer films there will be a point reached when the surface tensions of the liquid melts will exceed the...… Read More

While surfing the Web for nanolayer polymer applications, I came across several very interesting papers on PS/PP and PS/HDPE films with varying thickness polyolefin layers. The purpose of the...… Read More

In a previous post I showed how to generate nanolayers using a rotating die and a feedblock which coextruded separate polymers side by side. This relied on laminar mixing behavior of polymers to...… Read More

Early nanolayer films were produced on blown-film lines and made use of the laminar mixing behavior of high-viscosity polymer melts. Because the viscosities are so high, the flows never become...… Read More
