“…This reduction indicates an increase in the thermal stability of polymer matrix (PP) with increasing bio-filler content. The fillers absorbed more heat energy in the melting of the composites (Yao et al 2013;Gamon et al 2013). In the case of composites with coupling agent, it was observed that the melting enthalpy shows a lower value than those of binary composites that explained the high thermal stability of ternary composites (Ayrilmis and Kaymakci 2013).…”

“…The degree of crystallinity ( X c , %) was determined from the melting enthalpy values using the following Eq. 1 (Yao et al 2013): (1) where ∆H m is the melting enthalpy of the composites (J/g); 0 m H ∆ is the enthalpy value (theoretical enthalpy) of PP while being 100 % crystalline (209 J/g); (1 − α) is the weight fraction of polymer in the PP composites.…”

“…and automotive industry, which requires high performance, lightweight materials, minimum impact on the environment, and reduced cost of the material. However, the ultimate properties of the polymer composites are influenced by many factors such as the filler composition, filler size and morphology, filler loading, filler dispersion/distribution in a polymer matrix, processing methods, and interfacial interactions (Yao et al 2013;Elkhaoulani et al 2013).…”

The natural resource materials have an exceptional potential as reinforcement in plastic composites, due to their low cost, good mechanical properties, and biodegradability. This chapter is related to the use of some natural resources (nutshells residues) and their effect on polymer composite with varying filler reinforcement content and type or improving the adhesion between polymer matrix and filler. In this study, the used natural resources as bio-filler were almond shells, coir shells, argan shells, apricot shells, wood powder, and the mixture of these fillers, reinforcing thermoplastic polymer at various filler content (5, 10, and 20 wt.%), through extrusion and injection molding processes. The chemical and physical properties of the bio-filler and bio-filler/polymer composites were defined by using Fourier transform infrared spectroscopy (FT-IR); thermogravimetric analysis (TGA); differential scanning calorimetry (DSC); and tensile, torsional, and rheological tests. Depending on the bio-filler type, there was evidence that some particular difference in the chemical exists and also physical property changes. An increase in the crystallinity of composites is explained by the nucleating agent role of the bio-filler. The thermal, mechanical, and rheological properties of the composites were mostly enhanced with the addition of bio-fillers compared to the neat polymer matrix, and optimal properties were reached. Also, some optimal properties were observed when enhancing the interfacial adhesion by using a coupling agent. As a result, good final properties of the composites were manufactured with low cost. However, a fundamental understanding of the bio-filler structure and chemical composition could be beneficial to reach their full industrial applications.

“…According to the Taiwan Fisheries Yearbook, about 50,000 tons of clam are generated in Taiwan annually, and the shell accounts for about 70% of the total weight of each clam. Clam shells are rich in calcium carbonate (CaCO 3 , approximately 95 wt %) in the form of aragonite or calcite, which gives them the potential to substitute for commercial fillers (e.g., precipitated CaCO 3 ), for uses in plastics [2,3,4,5], and for uses as catalysts [6,7,8], and nanomaterials [9]. Given that these shells are cheap and abundant in nature, the capacity to convert them into phosphors could be of great benefit.…”

The increasing volume and complexity of waste associated with the modern economy poses a serious risk to ecosystems and human health. However, the remanufacturing and recycling of waste into usable products can lead to substantial resource savings. In the present study, clam shell waste was first transformed into pure and well-crystallized single-phase white light-emitting phosphor Ca9Gd(PO4)7:Eu2+,Mn2+ materials. The phosphor Ca9Gd(PO4)7:Eu2+,Mn2+ materials were synthesized by the solid-state reaction method and the carbothermic reduction process, and then characterized and analyzed by means of X-ray diffraction (XRD) and photoluminescence (PL) measurements. The structural and luminescent properties of the phosphors were investigated as well. The PL and quantum efficiency measurements showed that the luminescence properties of clam shell-based phosphors were comparable to that of the chemically derived phosphors. Moreover, white light-emitting diodes were fabricated through the integration of 380 nm chips and single-phase white light-emitting phosphors (Ca0.979Eu0.006Mn0.015)9Gd(PO4)7 into a single package of a white light emitting diode (WLED) emitting a neutral white light of 5298 K with color coordinates of (0.337, 0.344).

Abstract. Polystyrene (PP)/organoclay (OMMT) blends were prepared by co-rotating twin-screw extruder. The effects of OMMT on isothermal crystallization behaviors of blends was studied by differential scanning calorimetry (DSC). Using Avrami equation analysis the crystallization kinetics of materials. The analysis result shows that the OMMT act as effective nucleating agents, accelerating the crystallization of PP, then lead the rate of crystallization increased. Avrami exponent n is between 2.04~3.57, which indicating that PP/OMMT blends crystallization process might correspond to a two-dimensional or three-dimensional growth process. The activation enerigies for isotheraml crystallization were determined by the Arrhenius equation.
