epoxy is liquid so by using the ultrasonic to improve the dispersion on clay will me easy so far and the result will be good also , I used to used the same method last 3 years and got exfoliation structure inside the epoxy matrix 

thank you for your  reply 

keep in touch

Have you tried sonication method to disperse your hybrid nanocomposite? It might work.

it is good method but the problem is with sonication method after long time the filler will  be as big clusters 

 I guess the hybrid nanocomposite still have  a problem with stability  with sonication method. 

 Nanoemulsion having rationalized hydrophilic and hydrophobic component could be effective medium followed by sonication. The nanoemulsions in general produce higher friccohesity with weaker cohesive forces and higher percolating ability (higher viscosity) which could lead to disperse the hybrid nanocomposite. 

could you give more details on your material? Do you seek to disperse in aqueous environment or could be any solvent based?

my material is CNTs/ GNPs/ GNO/ silver nanoparticles  as a filler

the pure material is polymer such as PP or LDPE 

by using the melt blending 

thank you TItus Sobisch 

so are the nanoparticles included in PP or PE particles. How large are these. Or do you want to disperse the particles alone, which are now included in polymer matrix. If you name it filler, the polymer would be inside the nanoparticles, which sounds strange.

ok I will make it clear this time 

I have polymer  matrix ( polypropylene- melting ppint 180 _ 100g) want to add filler ( nanoparticles such as carbon nanotubes also graphene oxide  as hybrid filler different percentage 1-5%) by using the melt blending method 

hope this time it is clear prof 

Mouad according to my knowledge use combination of dispersion technique's ...Single technique like melt mixing might not work.

dear faizan 

by using this method we can see good dispersion so far but still we have big clusters inside the polymer matrix 

Dear Mouad Ahmad Tarawneh,  do you have infos from some Thermal (pre)treatment ?

Dear

Follow this paper

dear saeed 

thank for you sharing for epoxy it is easy to deal with it due to is liquid 

thank you again 

 dear pavel 

thank for your sharing 

sound is interesting hope will help me with my problem

Hi Mouad, 

Do you have the capability of ultrasonic homogenizer with high power? These devices make a differenceI think.  something like this https://www.hielscher.com/50h_p.htm

Oxygen or air plasma treatment is good enough to prevent aggregation of nanotubes in such a rapid way. You can read one of these works or ask me sth.

dear moaz 

it is working if we use liquid martix but I will use melt blending after we put the filler will see clusters 

dear andrea 

thank you for your sharing 

dear loannis 

do you mean thermal treatment for the filler !? if it is right yah I did with CNTs before 

Dear Sir,

For the better dispersion of nano clay or CNT, u can use the modification of nano particles using saline treatment of the fiber and clay particles. After saline treatment mechanical stirring and high shear homogenizer operation can be performed.

You can refer to this publication for the surface treatment:

Dear Sumit

thank you for your sharing , it is useful for nanocaly after treatment , but if we use the melt blending method will see agglomaration of nanoclay inside the polymer matrix

Dear Sir,

In our work, we generally used to mechanically stir the clay in to epoxy resin on hot plat by enhancing the temp of the epoxy to achieve lesser density, then ultrasonicate for desired time and then homogenize the mixture. And results were quite acceptable and exfoliation of the clay particle somehow achieved. clay used (closite 30B), with MBrace epoxy resin, Glass fiber unidirectional.

And wish you a luck for your future work. 

Zeta potential measurement and control might help to avoid/reduce agglomeration[1,2].
