“…These methods are environmentally friendly and do not involve the use of hazardous solvents. Many research works have reported the use of melt blending method [58,76,77]. One area of concern is the processing condition and the level of interaction between the fibers and the polymer matrix used.…”

Fiber-matrix interaction at the interphase is one very important property that is of great concern to all polymer scientists involved in polymer composites. Many of the failures can be traced to the type of interfacial interaction existing in the composites. That is why highlighting the factors that dictate the type of and the extent of interactions at the interphases become very necessary. Natural fiber polymer composites have found application in many fields of human endeavors. To continue this growth being experienced, the factors that determine the formation of good interaction at the interphase most be understood, so that they can be manipulated for a better result.

“…Extrusion and press moulding techniques are used in the production of chitosan and low density polyethylene (LDPE) films, which allow chitosan to perform antimicrobial activity on different bacterial strains [7,8]. Chitosan incorporation in a LDPE matrix or application by coating improves the barrier properties of LDPE and also confers antimicrobial characteristics, which makes it a very promising packaging material [9]. Chitosan film is used as an edible coating to prolong shelf life and preserve quality of fresh fish due to the antimicrobial action between the positively charged chitosan molecules and negatively charged microbial cell membranes [10].…”

“…In view of the above mentioned considerations, many researchers are working on blends of chitosan with various polymers either for increasing the bio-based content or for the antimicrobial effect of chitosan. Thus, the development of research about blends of chitosan with polyolefins has received considerable attention, especially those that are prepared by melt processing, because of their high yield, and greater control of the final material’s characteristics without atmospheric pollution, in comparison with the solvent evaporation methods [ 12 , 13 , 14 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 ]. However, there are only a few published reports on blends of chitosan with high density polyethylene (HDPE) [ 38 , 39 ], and, to the best of our knowledge, the compatibilization of these blends with organobentonite synthesized with quaternary ammonium salt impregnated chitosan has not been conducted yet.…”

In this study, blends based on a high density polyethylene (HDPE) and chitosan (CS) were successfully prepared by melt processing, in a laboratory internal mixer. The CS biopolymer content effect (up to maximum of 40%), and, the addition of bentonite clay modified with quaternary ammonium salt (CTAB) impregnated chitosan as a compatibilizing agent, on the properties of the blends was analyzed by Fourier transform-infrared spectroscopy (FT-IR), wide angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), thermogravimetric analyses (TG), tensile strength, and scanning electron microscopy (SEM). The use of clay modified with CTAB impregnated chitosan, employing a method developed here, improved the compatibility of HDPE with chitosan, and therefore the thermal and some of the mechanical properties were enhanced, making HDPE/chitosan blends suitable candidates for food packaging. It was possible to obtain products of synthetic polymer, HDPE, with natural polymer, chitosan, using a method very used industrially, with acceptable and more friendly properties to the environment, when compared to conventional synthetic polymers. In addition, due to the possibility of impregnated chitosan with quaternary ammonium salt exhibit higher antibacterial activity than neat chitosan, the HDPE/chitosan/organobentonite blends may be potentially applied in food containers to favor the preservation of food for a longer time in comparison to conventional materials.
