“…The alkalization process was implemented to increase the roughness of the fiber surface and consequently improve the fiber/matrix adhesion. The mixed treatment (alkalization + silanization), consists in the immersion of the previously alkalized fibers in a hydrolyzed solution with a silane agent (the silane works as a chemical coupling agent to improve the interactions between the fiber and matrix 13 ). The chemical surface treatments are briefly explained below.…”

“…Silanization process involves the use of a coupling agent (silane) that improves fiber/ matrix interfacial adhesion. [11][12][13][14] Several researchers investigated the effect of chemical treatments on the mechanical properties of the natural fiber reinforced composites. In general, it was shown that the concentrations of 2 and 5% NaOH provide an improvement in the mechanical properties of the studied composites.…”

“…15 The alkaline treatment improves the efficiency of other treatments and alters the fiber surface increasing adhesion. 13,16,17 Pinto et al 18 studied the effect of alkaline and silanized treatments on natural jute composites and showed that the treated composites presented a modulus of elasticity 300% higher than untreated samples.…”

The main objective of this work is to study the effect of chemical treatment on the thermal properties of hybrid natural fiber-reinforced composites (NFRCs). Different chemical treatments [i.e., alkalized and mixed (alkalized+ silanized)] were used to improve the adhesion between the natural fibers (jute, ramie, sisal, and curauá) and the polymer matrix. A differential scanning calorimetry, thermogravimetry, and a dynamic mechanical analysis were performed to study the thermal properties of hybrid NFRC. It was found that the chemical treatments increased the thermal stability of the composites. Scanning electron microscopy images showed that the chemical treatments altered the morphology of the natural fibers. A rougher surface was observed in case of alkali treated fiber, whereas a thin coating layer was formed on the fiber surface during the mixed treatment. However, for some fibers (i.e., sisal and rami), the chemical treatment has a positive impact on the composite properties, whereas for the jute and curauá composites, the best behavior was found for untreated fibers.

“…[1][2][3][4][5][6] Although several studies are still performed on fillers like clays, [7][8][9][10][11][12] calcium carbonate, 13,14 and carbon nanotube, [15][16][17] recent investigations focussed on natural fibers such as jute, hemp, flax, and sisal to improve the physical and mechanical properties of polymers. [18][19][20][21] These works used lignocellulosic fibers in thermoplastic materials to study the effect of processing methods and conditions, as well as coupling agent and fiber contents. [22][23][24][25][26] Among these studies, few of them used nano-crystalline cellulose (NCC) which is a rod-like, highly crystalline particle obtained from acid hydrolysis of cellulose.…”

Polypropylene (PP)/nano‐crystalline cellulose (NCC) composites and foams were produced through extrusion compounding combined with injection molding. From the samples produced, a complete morphological, physical, and mechanical analysis was performed to study the effect of NCC concentration (0–5wt %), foaming agent content (0 to 2wt %) and mold temperature (30°C and 80°C). NCC was very effective to reduce cell size (42–71%) and increase cell density (5–37 times) of the foams, while slightly increasing the overall density (2–7%). The results showed that NCC addition increased the specific tensile modulus (15–22%), specific tensile strength (1–14%) and specific flexural modulus (13–26%) of PP, but decreased specific impact strength (10–20%) and specific elongation at break (50–96%). © 2015 Wiley Periodicals, Inc.

“…However, functionalized AlN particles exhibited better dispersion in the matrix, due to the presence of surficial oligomeric silsesquioxane. On the other hand, oligomeric silsesquioxane improved the interfacial adhesion when one end of the molecule (ASiAOASiA) was tethered to the surface of AlN particles, and ACH 3 at the other end reacted with the polymeric phase in a noncovalent way [27,28]. In addition, functionalized AlN particles with smaller size could also provide a larger surface area to contact with polymer, demonstrating better particle dispersion in polymer-based composite [29].…”

Research and Development Department, Bomin Electronic Co., Ltd, Meizhou, ChinaAluminum nitride (AlN) with high thermal conductivity was blended in polyarylene ether nitrile (PEN) to obtain a composite system. A ball milling process could provide AlN particles of smaller size with higher surface silylation for homogeneous particle distribution in polymeric matrix. Thermal, electrical, and mechanical behaviors of the produced composites were characterized to investigate the effects of particles on the performance of PENbased composites with functionalized AlN. The composite exhibited thermal conductivity of 0.779 W m 21 K 21 ,a dielectric constant of 7.7, dielectric loss of 0.032, electrical resistivity of 1.39 GX.cm, and break strength of 36 N when the fraction of functionalized AlN increased to 42.3 vol%. A fitted equation based on the improved Russell's model could effectively predict a trend for thermal conductivity of the composite systems with consideration of interfacial resistance between AlN and surrounding PEN.
