How does one get hydrophobic particles into an aqueous ceramic-polymer mix without negating the enhanced ability of the hydrophobic particles to bond to the polymers?
Surfactant may create weak reversible bond. Make sure the functional groups of the particle are compatible with the polymer thus it can make strong covalent bonding during heating and casting.
I'm not a chemist but I'm trying to understand, I thought hydrophobic particle surfaces bond better to polymers than hydrophilic particle surfaces. My understanding is a surfactant would make the hydrophobic particles hydrophilic again and so I thought this would eliminate the ability of the hydrophilic particles to have the improved bonding to polymers that they get from being hydrophobic, yes, no?
Are there surfactants that don't affect a hydrophobic surface's superior ability to bond to polymers?
Dr Bugh interaction of filler also depend on type of polymer(polar or non polar)
Hi
Most of the thermosetting polymers are hydrophobic. They have Unsaturated OH in their structure. So if your particle is hydrophilic ir may easy react with polymer via donating electrons. Better make your particle surface as specific Functionalized it will be good than other surface option (hydrophobic or hydrophilic)
