ladies and gentlemen good morning um i would like to devise my five minutes
00:00:07
to show you how we utilise the intricate balances all it does a lot on multiple and scales
00:00:12
bowie as our main line of research but also to design novel are soft materials
00:00:18
that have interesting up ah a potential for technological application
00:00:25
so i'm sure that many of you know that my materials typically have extraordinary properties of or
00:00:30
unusual combinations of properties and typically the origin is what is called hierarchical structure formation
00:00:36
that is to say my materials have structuring or on many things yes
00:00:41
like other things yeah super molecular and scale novel microstructure and finally the microscopic shape
00:00:47
but as important as that structure and order actually is optional from your everyday life that
00:00:52
in this all those actually inevitable this is what my partner looks like everyday it
00:00:57
takes an enormous effort to clean it up again and the next day all by itself
00:01:01
well with my two little kids as the catalyst it looks again like this
00:01:05
but if this author's inevitable it will also inevitably be included
00:01:08
instructional materials but that is not necessarily short come
00:01:12
because if for example you want to create a structural material that is resilient you don't want it to be a
00:01:17
hundred percent is all that okay but you also do not want it to be a hundred percent or that
00:01:22
you want to maintain on certain length scales the balance of all dentist order and
00:01:26
as a matter of fact this is what really nature is a champion
00:01:30
and this is what we try to copy nor materials we try to balance all in
00:01:33
this order we try to control where this or that segment in our materials replace
00:01:37
we try to create order from this or don't another thing scale design materials that are
00:01:42
close to all that is all the transitions and finally make structural radiance that bland
00:01:47
smoothly all that in this ought to uh domains and so let me show you what this gives us
00:01:53
first of all we can for example modify soft
00:01:56
commercially available uh available come a commodity polymers
00:02:00
so that they become what is called thermoplastic estimates these are the
00:02:04
last summer's rubbers that can be processed from lowell disgusted emails
00:02:08
but at the same time they're actually reinforced by these uh another five girls that have
00:02:12
a short incorporated melting transition in this way we obtain alice the mess that
00:02:17
can be processed from the note that have high operating temperatures hi alice
00:02:22
this c. d. and a and a good mechanical properties overall
00:02:25
if we do it slightly differently we can use the exact same approach to achieve a
00:02:30
lesson as that have the exact opposite properties that are not elastic but highly dissipated
00:02:35
they serve as high performance than thing materials because they can contain to independence types
00:02:40
of super molecular networks that are formed spontaneously when crossing from the no
00:02:45
and so these materials outperform commercial high performance damping materials in that they're
00:02:50
highly dissipated show high moral bending racial combined with the high stiffness
00:02:55
more recently we have tried to organise a succeeded in actually
00:02:59
transferring the lessons learned in these last and the materials
00:03:02
two thermoplastic uh high temperature poly a might we actually design defects into
00:03:07
these poly a might so as to control the defect distribution
00:03:11
the order this or the interface and the no no structure of the crystalline uh the main c. d.'s materials
00:03:17
and it this way similar to spider so we've actually mount maintain commercial
00:03:21
a commercially applicable materials with an unusual combination of high strength and stiffness
00:03:27
drastically improve the today and so overall materials that optimised for a
00:03:31
high fracture energy as may be interesting for some engineering application
00:03:35
finally we've used that same idea of actually designing defects into material
00:03:41
to make not a card map nana coatings that contain a mono they of carbon
00:03:45
which however contains a control the amount of the fact sites that first of all sort of
00:03:50
to anchor the card into a solid substrate and secondly control the softest gonna show that carmen that
00:03:56
and so in this way but thank our model yes that may be interesting
00:04:00
in terms of where resistant lubricated recordings with some anti corrosive properties
00:04:06
so i was unable to show even at our lab we make and
00:04:08
characterise molecules but we ought to use them to make novel materials
00:04:12
that we character idling scales and we take care of applications properties and devices
00:04:18
we do so with a dedicated team of chemists material scientists and justices
00:04:23
and whereas i have not had time uh to actually explain to you all of my uh all of
00:04:29
our findings in much detail i'll be happy to answer
