1. Polyhedral Oligomeric Silsesquioxane (POSS) as Reinforcing Agent for Waterborne Polyurethane Coatings on Wood
Polyhedral oligomeric silsesquioxane (POSS) was added as a reinforcing agent in waterborne polyurethane (WPU)-based coatings to improve their properties. The morphology, structure, thermal stability as well as mechanical properties of the resulting WPU and WPU/POSS hybrid films were investigated. The good compatibility of POSS in the WPU matrices was demonst

2. Effects of polypropylene methyl polyhedral oligomeric silsesquioxanes and polypropylene-grafted maleic anhydride compatibilizers on the properties of palm kernel shell reinforced polypropylene biocomposites
Abstract The effects of the polypropylene-grafted maleic anhydride (PP-g-MAH) and polypropylene methyl polyhedral oligomeric silsesquioxane (PP-POSS) compatibilizers on the mechanical, thermal and physical properties of palm kernel shell (PKS) reinforced polypropylene (PP) were investigated. The production of PP/PKS biocomposites was performed by melt mixing

3. Marginal integrity of restorations produced with a model composite based on polyhedral oligomeric silsesquioxane (POSS)
Marginal integrity is one of the most crucial aspects involved in the clinical longevity of resin composite restorations. Objective To analyze the marginal integrity of restorations produced with a model composite based on polyhedral oligomeric silsesquioxane (POSS). Material and Methods A base composite (B) was produced with an organic matrix with UDMA/

4. Influence of the polyhedral oligomeric silsesquioxane n-phenylaminopropyl: POSS in the thermal stability and the glass transition temperature of epoxy resin
In this study, epoxy nanocomposites containing different fractions of n-phenylaminopropyl (POSS) were prepared. The nanocomposites were studied by transmission electron microscopy (TEM), gel content, dynamic-mechanical analysis (DMA) and thermogravimetric analysis (TGA). The parameters for Avrami's equation were calculated from the degradation curves. The di

5. Processamento reativo de nanocompósitos iPP-POSS
Os modos de interação de silsesquioxano poliédrico oligomérico (POSS) de gaiolas fechadas com distintos grupos funcionais foram avaliados na nanoestruturação de polipropileno isotático (iPP) via processamento reativo. Analisaram-se POSS com grupos substituintes isobutila, alila e vinila em concentrações de 0,5, 1, 2 e 5%m misturados a iPP fundido ut

6. Morfologia e propriedades térmicas de compósitos de HDPE/EVA com POSS
Neste trabalho foram estudados compósitos que apresentam como matriz polimérica uma blenda composta por polietileno de alta densidade (HDPE) e copolímero etileno acetato de vinila (EVA) e como nanocarga, silsesquioxano poliédrico oligomérico (POSS). Os compósitos foram processados em câmara de mistura fechada e caracterizados quanto às propriedades t
