4 days ago · Overview. Insulating your floor with polystyrene panels is a cost-effective way to help reduce your heating and cooling bills. We show you how to trim the panels to size and install them between your floor joists. You will also see how to use brackets to support the panels in place.
2 days ago · Abstract In this research, the morphology, rheology, and mechanical performance of polyamide 6/polylactic acid/acrylonitrile–butadiene–styrene (PA6/ABS/PLA) ternary blends were studied.
3 days ago · Ability of poly (styrene- alt -maleic anhydride) (PSMA) to undergo a conformational transition into an amphipathic α -helix coil offers one possible mechanism by which PSMA surface activity can ...
1 day ago · The studied polymer composites were obtained by incorporation of microalgal biomass into an SBS-based polymer matrix. The support material was prepared by mixing two types of SBS copolymers (LCY Grit Corporation, Taiwan, sorts Globalprene™ 3546 and 3501) having different styrene/butadiene ratios, and paraffin oil (Apar Ltd., Mumbai, India, with the density of 0.87 g cm-3, and viscosity of 18 ...
3 days ago · This study aimed to enhance the melt strength, foamability, and microstructural properties of poly (ethylene terephthalate) (PET) foam by addition of styrene maleic anhydride (SMA) as a chain extender. The addition of SMA to the polymer increased the complex viscosity by 375%. The calculated dissipation factor for chain-extended-PET (CE-PET ...
2 days ago · Here, Φ c of the PC/PVDF/MWCNTs-g-PMMA nanocomposites is significantly lower than the reported values for MWCNTs filled single polymer systems, e.g. 1.6 vol% for PC and 0.81 vol% for PVDF [48, 49]; it is also lower than most MWCNTs filled polymer blends, e.g. 0.017 vol% for MWCNTs filled PC/PVDF and 0.69 vol% for MWCNTs filled PC/PP/PP-g-MA ...
1 day ago · Here, we report a reverse-gradient BCP system, poly[(styrene-gradient-pentafluorostyrene)-b-4-tert-butyldimetilsiloxystyrene] [P(S-g-PFS)-b-P4BDSS] BCP, which enables universally vertically oriented lamellae even in the absence of a neutral layer, while also containing a Si-containing block with high etch resistance. The gradient block ...
