“…19 Brito et al 20 investigated the rheological behavior of PE/ PE-g-MA/Bentonite clay by torque rheometry, as PE-g-MA has a polar structure, interaction evidences between clay and PE were verified, resulting in higher torque values. In the present work, as PCL already presents a polar structure Gorrassi et al 21 , Wu and Liao, 22 suggest upon clay addition, its most like interactions take place even in the absence of PCL-g-MA, providing increased torque of both compositions, i.e., compounds with MMT and CLNa.…”

Biodegradable Poly (ɛ-caprolactone) (PCL) was compounded with Brasgel PA (MMT) and Cloisite Na (CLNa), and compatibilized with maleic anhydride grafted poly(ɛ-caprolactone) (PCL-g-MA). No evidence of degradation was verified during processing, as well as particle aggregates were absent as displayed through scanning electron microscopy (SEM) images. Compatibilized compounds upon clay addition achieved higher thermal stability as visualized by thermogravimetry (TG). Montmorillonite clays acted as nucleant agent during PCL melt crystallization as evidenced by differential scanning calorimetry (DSC). Mechanical behavior of PCL was preserved, and all compounds presented Elongation higher than 350% meanwhile the heat distortion temperature (HDT) was increased by 20% in PCL compounds, which may have wider range of application and better performance.

“…PCL-starch blends have been studied and the effects of starch on mechanical properties and biodegradation time were evaluated [10][11][12][13] . In addition, PCL-natural-organic fillers (eggshell, coconut, abaca, kenaf, seaweed, rice straw, sisal) composites have also been investigated 2,[14][15][16][17][18][19][20] . The advantages of using natural-organic fillers include low cost, high abundance and low density 2 .…”

Biodegradation Study of a Novel Poly-Caprolactone-Coffee Husk Composite Film

et al. 2016

Plastic disposal is a worldwide issue due to its long degradation time. Environmentally degradable polymers (EDPs) have received considerable attention because of their faster degradation. However, the use of EDPs is limited by high cost and restricted properties. The incorporation of organic fillers is an alternative to reduce cost while increasing biodegradation. Poly-caprolactone (PCL) is a biodegradable polyester compatible with organic fillers. Coffee husk (CH) is a sub-product of coffee processing with potential use as organic filler. We prepared a novel PCL-CH composite film and investigated the effects of CH incorporation on the biodegradation of PCL. Biodegradation study was carried out in soil for 120 days, and evaluated by weight loss measurements. Additionally, soil microbiological and granulometric analyses were performed. Bacteria and fungi were found in the soil that was classified as sandy. The composite film degraded twice faster than PCL film probably due to the adhesion of microorganisms on the coffee husk.

“…[4,5] The modification of fiber surface by chemical reactions in order to graft functional groups compatible with the matrix, [6][7][8][9] use of both surfactants or polymeric compatibilizer allowed the development of new materials with applications in high-performance fields. [10,11] Because of their good biocompatibility and nontoxicity, long-chain fatty acid esters are of particular interest, [12] stearoyl chloride being widely used to enhance cellulose hydrophobicity. [13] It is well known that the incorporation of lignocellulosic fibers into thermoplastic matrices enhances thermal and mechanical properties but also reduces the cost of the materials.…”

a Polylactic acid (PLA) was used as partial replacement for conventional thermoplastic matrix, new composites comprising cellulose, polypropylene (PP), and PLA being realized. In order to obtain a compatible interface between cellulosic pulp and polymeric matrix, two chemical modifications of cellulose with stearoyl chloride and toluene di-isocyanate (TDI) were performed, structural changes being evidenced by X-ray photoelectron spectroscopy and Fourier transform infrared spectroscopy. The composite materials were characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, dynamic scanning calorimetry, impact, tensile and melt rheological tests, surface tension, and dynamic vapor sorption. Because promising results for impact strength and Young modulus were recorded when replacing 15% of PP with PLA in blends of PP with the same cellulosic pulp load, the aim of our study was to assess the behavior to accelerate weathering of composites comprising PP, cellulosic pulp, and PLA. Although the slight decrease in the mechanical properties was recorded after accelerated weathering, the use of functionalized cellulose successfully prevented the deterioration of surface materials, especially for composite comprising stearoyl chloride treated cellulose pulp.
