Flaxseed gum (FSG) comprises neutral and acidic polysaccharides. Research shows that flaxseed gums with high arabi
noxylan concentration have shear thinning and weak gel-like properties, whereas those with high acidic monosaccharides
have decreased rheology. FT-IR and DSC tests described a bio-PCM composite made from flaxseed gum and fatty acid
anhydrides. The study examined how fatty acid type affects bio-synthesized composite materials made from flaxseeds and
various fatty acids with and without octadecane as phase transition materials. In the final composite structure, the fatty acid
backbone lengthened, increasing the host material’s latent heat. As phase transition material, 20% octadecane yielded best
results. Polymer-based materials (PCM) are used to make bio-synthesized composite materials from flaxseeds and stearic
acid. Latent heat of host materials increases with PCM content, optimum at 20% octadecane. The treated cotton cloth regu
lates temperature better than the untreated. The study shows that PCM composite material treatment creates a homogenous
thin coating on cotton fiber surfaces, improving thermal characteristics and heat retention.
