“…The intense peaks at 3500 to 3200 cm −1 indicated O-H groups in all materials because of the appearance of hydroxyl groups in cellulose, hemicellulose, and lignin related to the different water adsorption results found in this study. Finally, the peaks at 1800 to 1600 cm −1 implied carbonyl groups (C=O) in lignin and hemicellulose (da Silva et al 2016). Therefore, all FTIR spectrum bands acted from natural materials, which can be related to the chemical composition analysis of the natural cellulosic material reported here.…”

Coconut husk, rubberwood sawdust, and palm leaf base are cellulosic agricultural wastes that have potential to be processed to fiber as absorbing material. This study investigated characteristics (morphological, physiological properties, chemical composition, absorption capacity, and water absorption isotherms) of coconut, rubberwood, and palm fiber. Also, the study aimed to develop an antimicrobial sachet packaging to resist against foodborne pathogens (Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., and Escherichia coli) by adding lime oil (LO) emulsion or Litsea cubeba (LC) oil at 50 to 700 µL into the material (1 g) before, and then dried and placed in the 1-L seal box. Results showed that among the three, coconut performed the best in terms of releasing the essential oil (EO) emulsion against bacteria. Coconut could adsorb and release volatile LO or LC at the lowest concentrations (LO, 500 µL/L; LC, 300 µL/L) to inhibit bacteria compared with the other fibers (700 µL/L) at 35 °C. Results indicated that coconut has a low water absorption rate, which influenced the faster adsorption of EO emulsion in the beginning of the process; therefore, using low concentrations of EO in coconut for bacterial inhibition is possible. Coconut contains 34.5% lignin, 68.7% holocellulose, 37.6% cellulose, and 31.2% hemicellulose. Coconut is suitable as an alternative to the biocomposite material in developing a new antimicrobial packaging design.

“…Also, CH bands of the carbohydrates' aliphatic bonds at 2890 cm −1 are corroborated by the bending signals between 1500 and 1300 cm −1 . The peak in 1028 cm −1 corresponds to the CO stretching vibration in cellulose, hemicellulose, and lignin supporting the carbohydrate nature of the fibers, while the peak at 1235 cm −1 is attributed to the CO of the acetyl group in the lignin, finally the bands between 1500 and 1620 cm −1 are related to the stretching of the benzene ring of lignin 33,34 …”

In this work, biocomposites made of polyhydroxyalkanoates (PHA) with natural fibers were produced via compression molding. In particular, polyhydroxybutyrate (PHB) and polyhydroxybutyrate‐co‐hydroxyvalerate (PHBV) were reinforced with 20 wt% of agave fibers. Different compatibilization strategies were investigated to improve the fiber‐matrix interaction: fiber surface treatment in PHA solution, fiber surface treatment in maleated PHA solution, fiber propionylation, and extrusion with maleated PHA. The biocomposites were characterized in terms of morphology, mechanical properties, water absorption, and biodegradability by CO2production tracking. In general, fiber propionylation was the best strategy for mechanical properties enhancement and water uptake decreasing. Biocomposites with propionylated fibers showed improved flexural strength (170% for PHB and 84% for PHBV). The flexural modulus was also enhanced with propionylated fibers up to 19% and 18% compared to uncompatibilized biocomposites (PHB and PHBV, respectively). Tensile strength increased by 16% (PHB) and 14% (PHBV), and the water absorption was reduced using propionylated fibers going from 6.6% to 4.4% compared with biocomposites with untreated fibers. Most importantly, the impact strength was also improved for all biocomposites by up to 96% compared with the neat PHA matrices. Finally, it was found that the compatibilization did not negatively modify the PHA biodegradability.

“…It's possible to see the appearance of a band, at approximately 3300 cm -1 , corresponding to the O-H stretching, related to the hydroxyl groups from cellulose and lignin and also to the existence of adsorbed water molecules (P Ferreira et al 2018;Zouheyr et al 2015). The band peaking at * 2900 cm -1 , can be attributed to the asymmetric C-H stretching vibration of cellulose and hemicellulose (P Ferreira et al 2018;Zouheyr et al 2015) and the one peaking around 1020 cm -1 is related to the C-O stretch vibration (Silva et al 2016). The in situ synthesis of CaO NPs onto the jute, resulted in the appearance of the characteristic fingerprint peaks of CaO metal oxide, namely: O-H from Ca(OH) 2 , C-O, Ca-O-Ca and Ca-O bondings at 3640 cm -1 , 1400 cm -1 , 870 cm -1 and 710 cm -1 respectively (Anantharaman et al 2016;Bharathiraja et al 2018;Galván-Ruiz et al 2009;Tangboriboon et al 2012).…”

Fibrous based materials with exceptional functionalities have become a target of interest for researchers worldwide. One promising strategy for the development of active fibrous structures with improved functions is their functionalization with nanoparticles (NPs). In this work, jute fabrics were functionalized with calcium oxide (CaO) and silica (SiO 2 ) NPs in order to obtain fibrous structures with several properties including, hydrophobicity, UV protection, antibacterial activity and the degradation of dyes ability. CaO and SiO 2 NPs were synthesized via a simple in situ method, using sodium hydroxide (NaOH) as the reducing agent and water as solvent. Parallelly, the in situ synthesis of the CaO NPs was also tested. The final systems were fully characterized using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy, Ground-State Diffuse Reflectance and Field Emission Scanning Electron Microscopy and Energy Dispersive Spectroscopy. All these techniques confirmed the successful synthesis of the NPs as well as their well distributed presence onto the fabrics. The samples exhibited very good contact angle values, reaching 143.7°for the fabrics functionalized with CaO and SiO 2 NPs and great values of ultraviolet (UV) protection factors (UPF), reaching 50? for the functionalized fabrics. The developed systems also exhibited antibacterial activity against Staphylococcus aureus and Escherichia coli and photocatalytic activity for the degradation of methylene blue. The wash durability of the nanocoating was also evaluated, confirming that the SiO 2 improved the NPs' anchorage onto the fabrics. Overall, this work presents for the first time, the development of jute fabrics with CaO-SiO 2 NPs with several functionalities.
