Rice straw (Rs)/polypropylene (PP) composites were prepared in the different ratio of 5 : 95, 10 : 90, 15 : 85, 20 : 80, 25 : 75, and 30 : 70 (Rs wt % : PP wt %) by an injection molding process. This work investigated the tensile strength (TS), bending strength (BS), and impact strength (IS) of the composites. From the results, it is observed that Rs20 : PP80 mixture composite showed better performance with mechanical properties (TS ¼ 26.2 MPa, BS ¼ 58 N/mm 2 , and IS ¼ 1.7 KJ/mm 2 ) among the composites prepared. Two hybrid composites were also fabricated using 20% Rs, 10% seaweed with 70% PP and 20% Rs, 30% seaweed with 70% PP. In between the two hybrid composites, superior mechanical behavior showed by the hybrid composite in ratio of Rs20 : Sw10 : PP70 with enhanced results such as TS ¼ 28 MPa, BS ¼ 68 N/ mm 2 , and IS ¼ 2.5 KJ/mm 2 . Water uptake, simulating weathering, and soil degradation test of different composites were also performed.

“…Wood is a complex material which can be quite easily photo-degraded because of light absorption by chromophoric groups supported on lignin. 1,2 Among the solutions that can be proposed to protect wood against photodegradation, 3,4 the easiest is to apply finishes such as paints, coatings, varnishes etc. Photocurable finishes 5,6 are now more and more used in industrial wood joinery and their use should further develop in the coming years.…”

Photocurable finishes appear now as very attractive products for industrial wood joinery for reducing volatile organic compounds (VOC). Nevertheless their poor durability is currently reported. In this study, we aimed to enhance stability of advanced formulations based on photoinitiators working under UV-visible light by introducing UV absorbers, the absorption band of which is shifted compared to the band of initiators. We tested the efficiency of these stabilizers for two curable coatings applied onto oak and spruce. Modifications of samples at molecular and macroscopic scales were quantified after an accelerated ageing process by FTIR spectroscopy, measurements of color variations, apparition of cracks. It appears that both UV absorbers tested do not greatly improve the durability of systems and the results obtained allow to better understand the causes of the poor characteristics of the finishing systems.

“…that were industry standard ten years ago. They are always searching for a better product; a product that gives them desired properties with a minimum variation (Konica-Minolta 2007).Wood is available in a range of colours from almost white, as in the sapwood of many species, to almost black, as in the heartwood of black ebony (Hon and Minemura 2001). It can influence the market price of this ligno-cellulosic material.…”

“…It can influence the market price of this ligno-cellulosic material. As compared with the colour of other materials such as plastic and concrete, wood conveys peace of mind and a feeling of natural mildness (Hon and Minemura 2001, Esteves et al 2008, Rosu et al 2010, Dubey et al 2010.…”
