The review covers the understanding of nanostructure development in glassy and semicrystalline polymers as revealed by indentation hardness methods. microhardness polymer glasses is discussed emphasizing influence thermal history physical ageing. correlation between glass transition temperature brought in. Furthermore, role played lamellar morphology case amorphous blends a block copolymer homopolymer highlighted. A discussion on filler structure introduced. Indentation presented valuable...
Optimizing the interphase properties in polymer–fiber laminates represents a major issue development of materials for high structural applications. Carbon nanotube-based hierarchical composites offer challenging route to produce with enhanced interlaminar properties. The influence nanotube reinforcement on between polymer matrix and microfiber is concern drives present study. Nanoindentation used explore local mechanical single-walled carbon (SWCNT)-based multiscale (or hierarchical)...
The preparation of conductive nanocomposites poly(styrene-b-ethylene-co-butylene-b-styrene) (SEBS) triblock copolymers with chemically modified graphene is reported. Graphene has been functionalized short polyethylene brushes by thiol–ene click chemistry in order to enhance the interactions filler ethylenic phase block copolymer. presence modifies morphology SEBS domains, reducing their size and promoting an isotropic distribution cylinders arranged hexagonal packing, as shown SAXS, AFM,...
The reinforcing effect of inorganic fullerene-like tungsten disulfide (IF-WS2) nanoparticles in two different polymer matrices, isotactic polypropylene (iPP) and polyphenylene sulfide (PPS), has been investigated by means dynamic depth-sensing indentation. hardness elastic modulus enhancement upon filler addition is analyzed terms main contributions: changes the matrix nanostructure intrinsic properties including matrix-particle load transfer. It found that latter mainly determines overall...
Abstract The microhardness, H, of PMMA/natural rubber blends, prepared following the solution method has been investigated by means microindentation technique. Hardness changes are correlated with variation glass transition temperature. influence temperature and degree deformation on H were additionally examined. inclusion particles in PMMA matrix is shown to soften blends. micromechanical property at phase boundary polymer/rubber particle studied. Results reveal that drastically drops...
Mechanical properties of PVA are stabilized against moisture absorption by highly hydrophobic graphene.
Polymer nanocomposites with carbon nanotubes (CNT) are becoming important structural materials because of their superior mechanical properties and easy processability. The objective the work is to investigate influence small amounts single walled (SWCNT), as well multi-walled (MWCNT), on microhardness a thermoplastic polymer such poly(butylene terephthalate) (PBT). were obtained by introducing CNT into reaction mixture during synthesis PBT. polymers without (reference material) synthesized...
An experimental configuration that combines the powerful capabilities of a short-term shearing apparatus with simultaneous optical and X-ray scattering techniques is demonstrated, connecting earliest events occur during shear-induced crystallization polymer melt subsequent kinetics morphology development. Oriented precursors are at heart great effects flow can produce on (strongly enhanced formation highly oriented crystallites), their creation dependent material properties level stress...
