“…Dark colored fabrics have a higher UPF compared to lightcolored ones. 141 Several features of fabric determine its UPF: (a) the porosity of the material or how open the structure is will be inversely proportional to the UPF; (b) the absorption of UV by the fabric material; (c) dyes, chemical reactants, 43 or UV stabilizers 142 applied to the fabric; and (d) moisture level of the fabric. 143 Of these, the porosity or tightness of the weave is the dominant factor in obtaining UV radiation protection, followed by the ability of fibers to absorb UV radiation.…”

“…There is some evidence that the presence of wood in PVC-based WPCs may also promote photodegradation of the plastic matrix. 42 Naturally, the same light stabilizers used with plastics are also effective in protecting WPCs; for instance, the use of HALS stabilizers in wood-HDPE 42,43 and light absorber (benzotriazole type) in wood-PVC 44 composites have been successful. The extent of protection afforded depends on the level of the stabilizer and its dispersion in the polymer matrix.…”

Materials used in the exterior of buildings and in construction are routinely exposed to solar UV radiation. Especially in the case of wood and plastic building materials, the service life is determined by their weather-induced deterioration. Any further increase in ground-level solar UV radiation, UV-B radiation in particular, will therefore reduce the outdoor service life of these products. Any increase in ambient temperature due to climate change will also have the same effect. However, the existing light-stabilizer technologies are likely to be able to mitigate the additional damaging effects due to increased solar UV radiation and maintain the outdoor lifetimes of these materials at the present levels. These mitigation choices invariably increase the lifetime cost of these products. A reliable estimate of what this additional cost might be for different products is not available at the present time. Personal exposure to UV radiation is reduced both by clothing fabrics and glass windows used in buildings and automobiles. This assessment describes how the recent technical advances in degradation and stabilization techniques impact the lifetimes of plastics and wood products routinely exposed to solar UV radiation and the protection to humans offered by materials against solar UV radiation.

“…However, POSSs with multireactive groups as candidate regents, which can be crosslinked with polymer, are scarce. Reactive polyhedral oligomeric silsesquioxane containing multi-N-methylol (R-POSS) is a functional and attractive staring monomer for new reinforcement materials (Xie, Wang, & Xu, 2010;Xie, Zhang, & Chen, 2010). R-POSS has highly reactive multi-N-methylol groups and has excellent potential application as nano-sized cores for starburst dendrimers.…”

“…They have gained much interest due to the remarkable change in properties [15][16][17][18][19][20]. High-reactive polyhedral oligomeric silsesquioxanes may be utilized for preparing nano-cellulose hybrid materials [21,22]. In our recent work, novel high-reactive polyhedral oligomeric silsesquioxane containing multi-N-methylol groups (R-POSS) as POSS reagent was synthesized [23].…”

Novel nano-materials, nano-cellulose containing reactive polyhedral oligomeric silsesquioxanes with multi-N-methylol (R-POSS), were used for adsorption reactive dyes from dyeing wastewater solution. Langmuir isotherm mathematical model and Freundlich nonlinear isotherm model on the nano-cellulose were analyzed. Two reactive dyes, Reactive Yellow B-4RFN, Reactive Blue B-RN, were used in this study. The results showed that the adsorption capacity of nano-cellulose for reactive dyes was significantly higher than that of control cellulose.i
