Accelerated Weathering Effects on Poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV/TiO2 Nanocomposites [PDF]
Polymers, 2020 The effect of accelerated weathering on poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) and PHBV-based nanocomposites with rutile titanium (IV) dioxide (PHBV/TiO2) was investigated. The accelerated weathering test applied consecutive steps of UV irradiation (at 340 nm and 0.76 W m−2 irradiance) and moisture at 50 °C following the ASTM D4329 ...

Improving the Mechanical Properties of Biodegradable Polyhydroxyalkanoates via PHA–PHA Block‐Copolymer Synthesis [PDF]
Chemistry – A European Journal, Volume 32, Issue 39, 22 October 2026.Covalent linkage of a highly crystalline PHBV with a ductile P3HB4HB is shown to produce block copolymers with markedly enhanced extensibility and toughness, outperforming equivalent blends. The results demonstrate that polymer architecture, not composition alone, governs mechanical response, offering a route to biodegradable materials that combine ...

CRYSTALLIZATION BEHAVIOR OF INCOMPATIBLE PHBV/PS AND PHBV/PMMA CRYSTALLINE/AMORPHOUS BLENDS
Acta Polymerica Sinica, 2010 在不同的共混比例、不同的结晶温度下对不相容PHBV/PS、PHBV/PMMA结晶/非晶共混体系的结晶行为做了系统的研究.研究发现当PHBV含量为75 wt%时,共混体系仍然和纯PHBV一样生成环带球晶;而当PHBV含量为50 wt%时,共混体系在略低于非晶组分玻璃化转变温度时呈现花瓣状的球晶形貌;当PHBV含量为25 wt%时,PHBV/PS体系出现不规则的晶体形貌,而PHBV/PMMA体系在偏光显微镜下没有观察到晶体.在这种不相容共混体系中 ...

Dynamic mechanical properties of PLA/PHBV, PLA/PCL, PHBV/PCL blends and their nanocomposites with TiO2 as nanofiller [PDF]
Thermochimica Acta, 2015 Abstract The effect of blending and the addition of small amounts of TiO2 nanoparticles on the dynamic mechanical properties of PLA/PHBV, PLA/PCL and PHBV/PCL blends is reported in this paper. The storage modulus of the PLA/PHBV blends was higher than those of both PLA and PHBV in the temperature region below the glass transition of PHBV, but the PLA/

Properties of Luffa Fiber Reinforced PHBV Biodegradable Composites [PDF]
Polymers, 2019 In this study, composites of poly (hydroxybutyrate-co-valerate) (PHBV) with untreated luffa fibers (ULF) and NaOH-H2O2 treated luffa fibers (TLF) were prepared by hot press forming. The properties of luffa fibers (LFs) and composites were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and other ...
