Thermo-Oxidative Aging of LDPE/Stearoyl Chloride-Grafted Cellulose Nanocrystals Blown Films

Assessing the Effect of Cellulose Nanocrystal Content on the Biodegradation Kinetics of Multiscale Polylactic Acid Composites under Controlled Thermophilic Composting Conditions

“…Regarding the materials that contain cellulosic fibers, bands at 971 and 897 cm −1 can be seen which are characteristic of cellulose glycosidic bond stretching. Also, an increase in the width and height of peak at 2888 cm −1 can also be seen, assigned to cellulose CH and CH 2 bonds, after thermo-oxidation at 70 • C. This behavior suggests that cellulosic fibers could be degraded during thermo-oxidation [8,45,48].…”

“…The lyophilized cellulose nanocrystals were acquired from the University of MAINE, with 0.94% by weight of sulfur on a dry basis and were used as received. They were produced by acid hydrolysis of the wood pulp with an H 2 SO 4 solution (64% w/w) and had an average length of 296 ± 10 nm, an average diameter of 21.4 ± 2 nm and an average aspect ratio (L/D) of 14 [ 45 ]. The maleic anhydride powder 95% from Sigma-Aldrich was used as the coupling agent.…”

“…From 250 °C, a decrease in weight begins in the samples; however, from 280 °C, an anticipated loss of weight is observed for the three samples. This premature loss is due to the treatments carried out in the manufacture of the composite material, as well as the thermo-oxidative treatment, and this would indicate the beginning of the decomposition of PLA and cellulose [8,45]. in molecular weight [8,24,33,49,50].…”

Development of durable membranes for challenging wastewater treatment via membrane distillation

“…The acyl chloride group of FAC can react with the functional groups on ceramic membranes more easily as the chloride ion is a better leaving group than the hydroxyl group (Willberg-Keyrilä inen and Ropponen 2019). FAC has previously been studied to modify materials with rich -OH groups such as cellulose fibre, starch, chitosan, cotton, wood and paper to improve their dispersion ability, photostability or hydrophobicity (Carvalho et al 2005, Geissler et al 2014, Moo-Tun et al 2019, Prakash and Mahadevan 2008, Xin et al 2013). However, FAC has yet been used to modify ceramic membranes.…”
