Study of chemical and tensile properties of polyurethane and polyurethane/polyacrylonitrile coated bamboo fibers

The polyethylene glycol (PEG) based polyurethane (PU) and polyurethane-polyacrylonitrile (PU/PAN) semi-interpenetrating polymer networks (SIPNs) have been coated on the surface of alkali-treated and untreated bamboo fibers (Bambusa balcooa). The chemical resistance and tensile load at break of bamboo fibers before and after coating with SIPNs have been studied. It is observed that the tensile load at break and chemical resistance of bamboo fibers have increased on coating.
