Silica suspension for protective application

AI Thread Summary
The discussion centers around a thesis project focused on polymer dispersion for protective applications, specifically using shear thickening fluids in fabrics like sports pads and body armor. The materials under consideration are PMMA combined with PEG and colloidal silica with PEG. The choice of material depends on the specific protective needs, such as resistance to UV rays or moisture. The participant mentions a preference for using nylon and cotton fabrics over Kevlar due to cost constraints in Malaysia, despite acknowledging Kevlar's superior strength. Guidance is sought on the best material choice and approach for the thesis project.

i've 1 project for my thesis. its about polymer dispersion in the protective application...

i've 2 option of material
1. PMMA+ PEG
2. CATALLOID SILICA + PEG

u guys thinks which one is better...
i need some opinions from u guys...



anyway i from malaysia

What is your protective application? What are you protecting against? If you are trying to protect a surface exposed to hard UV rays the answer will be different than if you are trying to protect a surface from moisture.
 
i'm focus on polymer dispersion based shear thickening fluid-fabric for protection application... such as sport pads n body armor...

but i was not used neat kevlar for the fabric but i want used neat nylon n cotton...
even i know the strength of the kevlar is slightly higher than nylon n cotton...
in the malaysia,,,buy the excellent kevlar for my thesis is impossible because of the its price...

so, what do u think chemistree... i needs a guide from u for doing right thing in my thesis...
