“…First of them is related to the modification of the polymer matrix [55,56], while second is focused on size reduction [57], treatment or functionalization of cellulosic filler/fiber. In this subchapter we will focus on the second route related to the surface of filler/fiber, which can be successfully modified by silane treatment [58,59], mercerization [60,61], acetylation [62,63] maleic anhydride treatment [64], esterification and etherification [65,66], isocyanate [67], potassium permanganate [68] and other chemical treatment methods [69][70][71]. Furthermore, different kinds of surfactants and plasticizers applied as physical additives were considered as wetting agents to reduce the tensions in boundary between polymer matrix and reinforcement phase [72][73][74].…”

Abstract.Reactive extrusion is a cost-effective and environmentally-friendly method to produce new materials with enhanced performance properties. At present, reactive extrusion allows in-situ polymerization, modification/functionalization of polymers or chemical bonding of two (or more) immiscible phases, which can be carried out on commonly used extrusion lines. Although reactive extrusion has been known for many years, its application for processing of bio-based polymer blends and composites is a relatively new direction of scientific research. This work presents a literature review on recent advances in the processing of bio-based polymer blends and composites via reactive extrusion. We described compatibilization mechanisms for different types of biodegradable polymeric materials based on: (i) aliphatic polyesters, (ii) aliphatic polyesters/starch and (iii) aliphatic polyester/natural rubber systems. A special attention was focused on conventional and dynamic cross-linking of bio-based polymer blends and composites as an effective way to prepare new materials with unique properties e.g. biodegradable thermoplastic elastomers or shape-memory materials. Advantages and limitations affecting future trends in development of biodegradable polymer blends and composites reactive extrusion are also discussed.

“…The number average diameter ( -D n ), weight average diameter ( -D w ) and poly dispersity index (PDI) of the 5 phr and 10 phr blends were calculated using the Equations (9), (10) and (11): (9) (10) (11) where n i is the number of domains having diameter d i . The interparticle distance and interfacial area per unit volume were calculated using the Equations (12) and (13) [27]:…”

“…Thermosets have historically been the principal matrix material for fibre reinforced composites for many applications [8][9][10]. A great deal of research interest has been made on the study of the wetting phenomena of polymeric systems [11][12][13]. An appropriate experimental technique for quantifying the surface properties of solids is the measurement of contact angles of liquids on solid surfaces.…”

Abstract. In this study, the surface characteristics of blends and composites of epoxy resin were investigated. Poly(styreneco-acylonitrile) (SAN) was used to modify diglycidyl ether of bisphenol-A (DGEBA) type epoxy resin cured with diamino diphenyl sulfone (DDS) and the modified epoxy resin was used as the matrix for fibre reinforced composites (FRP's). E-glass fibre was used as the fibre reinforcement. The scanning electron micrographs of the fractured surfaces of the blends and composites were analyzed. Morphological analysis revealed different morphologies such as dispersed, cocontinuous and phase-inverted structures for the blends. Contact angle studies were carried out using water and methylene iodide at room temperature. The solid surface energy was calculated using harmonic mean equations. Blending of epoxy resin increases its contact angle. The surface free energy, work of adhesion, interfacial free energy, spreading coefficient and Girifalco-Good's interaction parameter were changed significantly in the case of blends and composites. The incorporation of thermoplastic and glass fibre reduces the wetting and hydrophilicity of epoxy resin.

“…The surface of natural fibers is generally chemically modified to minimize the wetting of fibers in addition to improve the interface between the matrix and the reinforcement. Some chemical surface modification techniques include treatment with sodium chlorite [4], methaacrylate [5], isocyanate [6], silane treatment [7], mercerization, acetylation [7], etherification [9], enzymatic treatment [10], peroxide treatments, benzoylation [8], dicumyl peroxide treatment [6], plasma treatment [11], ozone treatments [12], and grafting. The oxidation of polyolefins [13], has also been described to improve the incompatibility between the surfaces of natural fiber and polymer matrix.…”

Abstract. This study was focussed to investigate the effect of fluorocarbon, hydrocarbon and hybrid fluorocarbon on the mechanical properties and moisture regain of jute fiber reinforced composites. A significant difference in moisture regain values of treated and untreated reinforcement samples was observed at a concentration of 40 g/l. The composite made from treated reinforcement regained very low moisture content and exhibited improved mechanical properties (tensile and flexural strength). Being dual nature (hydrophilic and hydrophobic groups) of Hybrid fluorocarbon, the treated jute fibers and corresponding composites showed better properties as compared to other two chemicals due to better interface.
