Hi Shakeel, 

Many polymers are in use with chitosan this days, you may search in online databases to find list of them. but its depends on your goal and your final scope for example you can begin your search with PCL, may help you. 

Vahid

what chitosan are you using? Water soluble? 

Dear all,

I think grafting is by far more suitable than blending (which is always accompanied by phase separation and the use of compatiblizing agents). On the other side with chemical grafts it impart hydrphobocity is widely used and investigated for mainy polymers including polycarbohydrites. By simple search with the keyword "hydrophobically modified polymers" pleinty of docs will be available. Regards

Dear Saniyat Islam

I am using chitosan from shrimp shell >75% DD 

It is important to know the type of chitosan first-tah decide what to do

hi shakeel,

chitosan which you are using is water soluble? or it is acetic acid soluble. 

Dear Menaka Ramanathan

The chitosan which i am using is soluble in acetic acid.

Hi shakeel,

Ok. are u getting a hydrogel products with chitosan. have u tried any synthesis with chitosan. if i am not wrong,  you want chitosan grafted polymers but not hydrogels.?  am I getting you correct ? 

To decrease the hydrophilicity of Chitosan, the hydrophobic biopolymer like Polyhydroxyalkanoates can be used as a blend component.

Hi Menaka

I am trying to fabricate chitosan based films for food packaging. I want to increase antimicrobial properties along with its tensile strength. 

Hi

you can blend the chitosaan with silver nano(micro)particles .

Hi,

old question but the general idea is to reduce the polarity (charges) on chitosan molecules. Sometimes you can observe sufficient reduction of hydrophilicity by formation of salts when using for instance acetic acid as a solvent

Dear Ahmed,

Pls follow the link which may helpful for your research.
