Hello everyone, I am new in this forum. I don't know if the topic has been already dealt with. But I am quite surprised not finding information about basic properties of bio- polysaccharides. I desperately look for the temperature of auto-ignition of Acacia gum, arabinoxylan and agarose  . Someone has some  information?

Thanks in advance

Have you tried the MSDS for these reagents?  If you have some, you should have or have access to the MSDS.  Thing is, not every stat for every chemical is known.  What is you application, for agarose, with regard to its autoignition?  Its organic, and will likely burn as a bulk dry powder, but its usually used as a hydrogel that wont likely burn until all the water is gone.  Unless you have to certify a warehouse where kilos are stored dry.  Or some other application.

Thank you for your reply. I would like to make metal -polymer nanocomposites that I will deposit on glass substrate. The device made should be conductive.  I need to find a film-forming agent. I was thinking to bio polymers because they form homogenous films. I have tried with ethyl cellulose. Unfortunately to make conductive device, I had to remove the polymer by annealing at 400 degrees !!! At this temperature, my metal particles were totally destroyed. So I need to find a polymer with a lower temperature of auto-ignition.

 I am a bit desperate lol : I am quite surprised that this type of data is not available for many polysaccharides (o_O ).

 For agarose, I was wondering if in presence of organic solvent, the gelification will still occur . Maybe my idea was totally stupid but I was thinking that during the step of Annealing ( under nitrogen) , the polymer will degradate leaving a super conductive film :-D :-D

Now that I am stuck, I am asking myself why I did not follow my bio polymer lessons with more care.... ><__><
