“…Also apparent in and C 2 PVC/bamboo composites. This suggests the thermal properties of PVC in the composites were independent of the content of various processing lubricants used which was consistent with previous analyses of related PVC/bamboo composites [25]. In comparing the two bamboo particle sizes, DMTA revealed no clear trend between use of 1 mm and 75 m particles across the C 1 and C 2 composites and bamboo content.…”

Polyvinyl chloride (PVC)/bamboo composites have been prepared and assessed for their use in interior and exterior loadbearing applications. PVC composites were formed by compounding PVC with different bamboo particle sizes and loadings. The mechanical properties of these composites were determined at both ambient and elevated temperatures and after long-term water soaking. Analysis revealed that bamboo incorporation improved the PVC composite flexural modulus which was also observed with dynamic mechanical-thermal analysis on heating composites to ca. 70 ∘ C. Addition of 25% and 50% bamboo particles increases flexural modulus by 80% with dependency on whether fine (<75 m) or coarse (<1 mm) particles were used. On water soaking to saturation, composites had water weight uptakes of 10%, with reduced flexural properties obtained for all water-soaked composites. Nonetheless, the results of this study show that PVC/bamboo composites achieve the minimum flexural performance of ASTM D 6662, indicating potential for their use in exterior applications.

The nanocellulose and its nanocomposites have significant importance in the most economic sectors of applications. This research involves the synthesis of nanocellulose from Albizia lebbeck wood sawdust. Quantitative evaluations of chemical components present in the sawdust of a native hardwood species Albizia lebbeck were determined by chemical analysis method. The results revealed that the approximate amount of hot water extractives, 96% ethanol extractives, alpha-cellulose, hollocellulose, hemicellulose, lignin and ash content were 6.9%, 7.31%, 40.72%, 65.10%, 24.38%, 25.67%, and 1.10% respectively. Nanocellulose was synthesized from the extracted alpha-cellulose by acid hydrolysis method. Fourier-transform infrared spectroscopy (FTIR) characterizations have been done for Albizia lebbeck sawdust, extracted alpha-cellulose and synthesized nanocellulose respectively. The average diameter of synthesized nanocellulose was found 155.6 nm by particle size analyzer. Nanocellulose with different weight percentages (2%, 4%, 6%, 8% and 10%) were reinforced with poly(vinyl chloride) (PVC) to prepare nanocomposites by solution casting method. The thermal stability of pure PVC, nanocellulose and 2wt% nanocellulose–PVC nanocomposite was investigated and the result revealed that 2 wt% nanocellulose reinforced PVC nanocomposites is thermally more stable than the nanocellulose and pure PVC. The tensile properties of all nanocomposites were counducted by universal testing machine (UTM) and the highest tensile strength was obtained for 2 wt% nanocellulose reinforced PVC nanocomposites. The scanning electron microscope (SEM) images of 2 wt% nanocellulose reinforced PVC nanocomposites also exhibited the uniformly dispersion of nanocelulose in nanocomposite.

Banbuak, geometria tubularra duen landarea, eraikuntzaren sektorerako material sintetiko tradizionalen ordezko aukera interesgarriak aurkezten ditu. Gainera, ingurumenarekiko iraunkorra eta berriztagarria da. Hala ere, bere erabilera sustatzeko banbuen propietate mekanikoak eta kimikoak ezagutzea beharrezkoa da. Lan honek, gaur egun eraikuntzan ezezagunak diren baino tradizionalki oso erabiliak izan diren hiru espezie, kimikoki eta mekanikoki aztertzen du: Phyllostachys aurea (PA), Arundinaria amabilis (AA) and Dendrocalamus strictus (DS). Azterketa kimikorako TAPPI arauak erabili dira, eta ezaugarri mekanikoak konpresioan eta dinamometroarekin makurdura hiru puntutan neurtuta aztertu dira. Propietate mekanikoen emaitzek erakutsi dute banbuaren dentsitateak eragin zuzena duela, bai erresistentzia, baita zurruntasun ikuspuntutik ere. Aztertutako hiru banbu espezieetan, dentsitatea zenbat eta handiagoa izan, erresistentzia eta zurruntasuna handiagoa dela ikusi da.
