dc.description.abstract | Hemicelluloses are known to have good gas barrier properties makes them of interest to film applications.
Corn cob, cotton waste, olive, apple tree pruning, pepper and chilli wastes were used as hemicelluloses
sources for films production. Hemicelluloses were recovered from these wastes by direct alkaline
extraction and raw material delignification. The hemicelluloses and their films were characterized
using different analytical techniques (IR-ATR, TGA, DSC, HPLC, nitrobenzene oxidation, GPC, 13C NMR,
DMA). Hemicelluloses obtained by direct alkaline extraction produces brownish films (≤4.46% lignin,
Mw = 30,997–91,796, Tg = 140–150 ºC). The presence of lignin and Ara/Xyl enhanced the film forming
properties. Delignified hemicelluloses produced less colored films (Mw = 17,449–20,180, Tg = 140–150 ◦C)
and Ara/Xyl ratio improved film forming capacity although a possible cellulose contamination could be
observed. This study demonstrated the suitability of different agricultural wastes for hemicelluloses
recovery and their physico-chemical properties for first step film elaboration. | es_ES |
