The successful development of durable wood-plastic composite (WPC) cladding poses a challenge, hence investigating the effects water immersion-freeze-thaw treatment on physical properties, flexural strength (FS), and morphology wood-recycled polypropylene composites. behavior wood plastic is difficult to predict due complexity structure material. Wood consists cells (fibers) arranged in an intr...

Fabrication of biodegraded composite from polypropylene, polypropylene grafted maleic anhydride, and chempedak seed (Artocarpus integer) starch has been conducted. The stages were prepared Cempedak seed, grafting process anhydride on fabrication with a composition ratio PP: PP-g-MA: (9.5:0.5:0.1)g, (9.5:0.5:0.2)g, (9.5:0.5:0.3)g, (9.5:0.5:0.4)g, (9.5:0.5:0.5) g, (10:2)g. composites obtained cha...

Unique properties of nanohybrid composites based on different types of porous polymer matrices doped with fluorescent nanoparticles (quantum dots, QDs) are determined by the combination of the mechanical properties of the host matrix (flexibility, chemical stability, etc.) and a high luminescence intensity and extreme stability of QDs. Here, we report on the preparation, optical and microstruct...

Composite biomaterials, which consist of a polymer matrix and a particulate bioactive phase and are hence analogous to bone microstructure, have been developed for human hard tissue substitution. In this investigation, a manufacturing route employing injection moulding was established for producing bone analogue biomaterials. Using this manufacturing technology, a potential bone replacement mat...

The superior oil absorption capacity of recycled polypropylene (PP) fiber and waste tire powder were used to recover spilled engine oil. We used ASTM F726-99 method to evaluate oil adsorbing capability of PP fiber and found it to have a large, rapid oil sorption capacity. However, its lack of elasticity dramatically limited that capacity after repeated use. Tire powder, which absorbs less oil m...

Textile composites are the materials in which the composition and internal structure is changed under controlled conditions so as to match their performance to the most demanding structural or non-structural roles. Textile reinforcement structure can be made of fibers, yarns or fabrics (woven, braided, knitted or non wovens) and are generally flexible. The application of traditional textile tec...

We report the design, synthesis, morphology, phase behavior, and mechanical properties of semicrystalline, polyolefin-based block copolymers. By using living, stereoselective insertion polymerization catalysts, syndiotactic polypropylene-block-poly(ethylene-co-propylene)-block-syndiotactic polypropylene and isotactic polypropylene-block-regioirregular polypropylene-block-isotactic polypropylene...
