To reduce TVOC emission from bio-composites, we used to various experimental using TE method, FLEC method and 20l small chamber. The TVOC of neat matrix was more emitted with increasing temperature. Above 70℃, all composites which are higher TVOC emission factor than that of neat matrix, because of rapidly natural VOCs, such as furfural (2-furancarboyaldehyde). PLA composites with flours had high 1,4-Dioxane reduction ability above 50% as the flours occupied as 30 wt% of PLA composites. TVOC of PBS was emitted rapidly from 50℃ to 90℃, because of succinic from pyrolysis of PBS. We confirmed TVOC emission factors of PLA bio-composite and PBS bio-composites were reduced according to bake-out method (temperature at 70℃ and baking time 5 hours). |
