This experimental study is conducted to investigate the effects of boric acid additive into polypropylene in terms of microstructure formation and thermal properties. Boric acid granules are added into pure polypropylene at three mass rates of 0.5, 1.5, and 2.5% which are notated as PP/BA-0.5, PP/BA-1.5, and PP/BA-2.5, respectively. The pure polypropylene material (pure PP) and boric acid reinforced polypropylene composite materials (PP/BA) are manufactured in an injection molding machine. The m...

In this study, a low-cost thermoset such as unsaturated polyester resin (UPR) was used for the preparation of lightweight and thermal insulation polymer composite using rice husk-derived silica aerogel (SA) as filler. For the first time, hydrophilic and hydrophobic silica aerogel (SA) of similar physical properties were added to the UPR to study the effects of SA surface polarity on the mechanical tensile and thermal properties of the composites. The composites with 40% and 60% of SA filler by v...

Carbon dioxide (CO2) capture from natural gas, and further utilization is an essential issue for greenhouse gas reduction. Poly(ionic liquid)s (PILs) assemble ILs unique properties, with those of polymers being versatile materials for CO2 capture from flue gas (CO2/N2) and natural gas (CO2/CH4). PILs based on polyurethanes obtained with different polyols and ILs cations were blended in different proportions aiming to improve PILs CO2 sorption capacity. Two different polyols structures (PC and PG...

Polyvinylidene fluoride (PVDF) is a common semicrystalline fluoropolymer polymer. Due to its excellent piezoelectric properties, thermal stability, and mechanical strength, it has excellent processability and chemical tolerance to a range of materials such as acids, bases, organic solvents, grease, and fat. The current research provides an overview of recent advancements and developments in the implementation and modification of PVDF membranes, with a particular emphasis on sensors, biomedical e...

Polymers with new C–N bond formation between monoethyleneglycoldimethacrylate and substituted amines at 100 °C under nitrogen atmosphere with vigorous stirring condition and without any catalyst or a solvent via aza-Michael addition (AMA) reaction was synthesized. Thus, synthesized polymer was characterized by FT-IR spectroscopy, UV–visible spectra, DSC, TGA, XRD, SEM and intrinsic viscosity measurements. Further, the adsorption behaviour of the same was tested towards the methyleneblue (MB), co...

Branched polyesters based on the polyethylene terephthalate were synthesized by incorporating isophthalic acid (IPA) and trimellitic anhydride (TMA). TMA has the branching agent role. During the esterification step, only terephthalic acid, IPA, and ethylene glycol were reacted and TMA was added at the beginning of the polycondensation step. Reaction progress was studied using water production and mixing torque increase during esterification and polycondensation steps, respectively. Polycondensat...

New pH-sensitive polysaccharide supramolecular hydrogel microparticles (HMPs) were constructed based on carboxymethyl β-cyclodextrin/chitosan inclusion complex (CM-β-CD/CS) and EDTA-chitosan (EDCS) in aqueous solution. The incorporation of components in HMPs was characterized by ultraviolet, fluorescence and FTIR spectroscopy. The morphology measurements of HMPs were investigated by particle size analyzer and fluorescence microscope. These results showed that CM-β-CD was integrated on the CS by ...
