Abstract: The objective of this study is to develop a new biocomposite material with high deformation ability. In this regard, the thermal, rheological, and thermophysical properties of this new composite were characterized as a function of temperature and filler concentration. High density polyethylene (HDPE) was the matrix of this new composite which was reinforced with six sawdust con- centrations 0%, 20%, 30%, 40%, 50%, and 60%. Maleic anhydride grafted polyethylene (PE-g-MA) was used as coupling agent. Addi- tion of sawdust with PE-g-MA increased significantly the complex viscosity, the storage modulus (G 0 ), and loss modulus (G 00 ) of the matrix. The superposition of the complex viscosity curves using temperature dependent shift factor, allowed the construction of a vis- cosity master curve covering a wide range of temperatures. Arrhenius law was used for the relationship of the shift factor to tempera- ture. Furthermore, method of Van Gurp and Palmen (tan delta vs. G*) is also used to control the time-temperature superposition. The experimental results can be well fitted with the cross rheological model which allowed the prediction of the thermorheological properties of the composites over a broad frequency range. By increasing wood concentration, both the activation energy and relaxa- tion time for the biocomposites determined using, respectively, the Arrhenius law and the cole-cole rule increased. By contrast, spe- cific heat of the matrix decreased with sawdust addition while its dimensional stability improved. V C 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40495.

TL;DR: In this paper, the removal performance of BPA by β-cyclodextrin (β-CD) modified pine sawdust (CD-PS) in an aquatic environment was evaluated.
Abstract: The occurrence of bisphenol A (BPA) raised significant concerns about potential adverse impacts on environmental health, and its removal has become a hot research topic. We conducted batch adsorption and photo-degradation experiments to determine the removal performance of BPA by β-cyclodextrin (β-CD) modified pine sawdust (CD-PS) in an aquatic environment for the first time. Pine sawdust (B-PS) was treated by NaOH firstly and then modified by β-CD. The adsorption behaviour of BPA on the B-PS and CD-PS were observed to follow Langmuir and pseudo-second-order kinetic models, and that CD-PS had a 1.2 times higher adsorption capacity than B-PS. At 25 °C and pH = 7.0, the maximum adsorption capacity of CD-PS reached 0.0319 mmol/g. Moreover, the effects of β-CD, CD-PS and B-PS on the photo-degradation of BPA were compared under UV irradiation, indicating that CD-PS significantly enhanced the removal efficiency. Additionally, the “saturated” CD-PS could be regenerated several times using UV irradiation without loss during BPA adsorption process. Results of this work demonstrate that β-CD immobilized on the surface of CD-PS could be acted as an excellent catalyst for BPA removal, and a possible reactive mechanism was further proposed in this regards. These observations indicate that the CD-PS system can remediate BPA-polluted aquatic environment very well.
