However, fabrication of fibrous materials with high POSS content has been a challenge because of the aggregation and solubility limits of POSS units. In this paper, we describe a robust and environmentally friendly fabrication approach of inorganic-organic hybrid POSS fibers by integrating UV initiated thiol-ene polymerization and centrifugal fiber spinning. The use of monomeric liquids in this approach not only reduces the consumption of heat energy and solvent, but it also promotes homogeneous mixing of organic and inorganic components that allows integration of large amount of POSS (up to 80 wt %) into the polymer network. The POSS containing thiol-ene fibers exhibited enhanced thermomechanical properties compared to purely organic analogs as revealed by substantial increases in residual weight and a factor of 4 increase in modulus after thermal treatment at 1000 degrees C. This simple fabrication approach combined with the tunability in fiber properties afforded by tailoring monomer composition make POSS containing thiol-ene fibers attractive candidates for catalyst supports and filtration media, particularly in high-temperature and harsh environments.</p>10across-linked fiber10aenhanced thermomechanical properties10ainorganic-organic hybrid fiber10aPOSS10areactive centrifugal spinning10athiol-ene photopolymerization1 aFang, Yichen1 aHa, Heonjoo1 aShanmuganathan, Kadhiravan1 aEllison, Christopher, J.  uhttps://library.ncl.res.in/content/polyhedral-oligomeric-silsesquioxane-containing-thiol-ene-fibers-tunable-thermal-and
