Graphene possesses not only excellent optical, electrical and thermal properties but also outstanding thermoelectric photothermal conversion capabilities. The application of graphene with functional responses plays a vital role in the development intelligent materials intended for flexible actuators robots. Cellulose paper is foldable hydrophilic network comprised porous cellulose fibres. In th...
This paper investigates the potential of recycling waste copper chromium and arsenic (CCA)-treated timber for use as a reinforcement material in wood–plastic composites (WPCs) produced construction, including an assessment mechanical properties leaching heavy metals. Wood flour was obtained through grinding, fibres were alkaline digestion followed by bleaching. Composites with 40 wt.% bleached ...
In this study, oil palm empty fruit bunch fibres (EFB) reinforced polypropylene (PP) composites were prepared by two different methods i.e. physical treatment of the composites using electron beam irradiation and chemical treatment by adding coupling agent such as maleated PP. The composites pellets were then subjected to injection moulding for preparation of test pieces for physical, mechanica...
Polypropylene and PA66 are widely used in our daily life, but they cannot be welded by laser transmission welding (LTW) because of polar differences and poor compatibility. In this paper, grafting modification technology is used to improve the welding performance between polypropylene and PA66. Firstly, the strong reactive and polar maleic-anhydride (MAH) is grafted to polypropylene and infrare...
