Journal of Polymer Materials, Vol.41, No.2, pp. 87-103, 2024, DOI:10.32604/jpm.2024.054660
Abstract In this research, we developed a novel photo-stimulation-responsive composite sphere with a semi-interpenetrating polymer network (semi-IPN) structure, synthesized via an alkali gel method, to enhance the efficiency of agrochemicals. Chitosan (CS) serves as the structural matrix and protective shell, with a loading capacity for the plant growth hormone indole-3-butyric acid (IBA) of up to 41.73 μg/mg, effectively controlling the abrupt release of auxin. The incorporation of photothermal detonation nanodiamond (DND) and the photosensitive poly(N-isopropylacrylamide) (PNIPAm) endows the spheres with the ability to respond to light and temperature stimuli, achieving intelligent control over IBA release.

Rheological Investigation on a Polypropylene/Low Density Polyethylene Blending Melt
Journal of Polymer Materials, Vol.41, No.1, pp. 45-54, 2024, DOI:10.32604/jpm.2024.053021
Abstract Polymer blending with co-continuous morphology has garnered the interest of many researchers, but corresponding rheological models are rarely presented. In this study, the dynamic rheological behavior of a blend of polypropylene (PP) and low-density polyethylene (LDPE) in the ratio of 50/50 wt% is investigated, and a rheological model suggested by Yu et al. is used to fit the dynamic modulus. The rheological measurement shows that at low frequency, pure PP has higher complex viscosity and dynamic modulus than LDPE. SEM images reveal that the morphology among the 40/60 and 60/40 blends is non-dispersive. The fitting… More >

composites with low level of filler loading. Styrene butadiene rubber (SBR) is a non-polar rubber
which acts as an insulator and has low electrical conductivity. Graphene platelet nano-powder
from 0.1 to 1.25 phr level is incorporated into SBR rubber in order to improve the electrical
properties. Comparative studies on electrical and mechanical properties of styrene butadiene
rubber with graphene platelet nano-powder (GPN) by varying the filler content are made. The
incorporation of Graphene platelet nano-powder increases the electrical conductivity in styrene
butadiene rubber. More >

Optimizing Hybrid Fibre-Reinforced Polymer Bars Design: A Machine Learning Approach
Journal of Polymer Materials, Vol.41, No.1, pp. 15-44, 2024, DOI:10.32604/jpm.2024.053859
Abstract Fiber-reinforced polymer (FRP) bars are gaining popularity as an alternative to steel reinforcement due to their advantages such as corrosion resistance and high strength-to-weight ratio. However, FRP has a lower modulus of elasticity compared to steel. Therefore, special attention is required in structural design to address deflection related issues and ensure ductile failure. This research explores the use of machine learning algorithms such as gene expression programming (GEP) to develop a simple and effective equation for predicting the elastic modulus of hybrid fiber-reinforced polymer (HFPR) bars.

Journal of Polymer Materials, Vol.40, No.3-4, pp. 205-214, 2023, DOI:10.32381/JPM.2023.40.3-4.6
Abstract In current research work, we have studied the blending effect of non-mulberry silk fibroin (10%
weight/volume basis) and gelatin (20% weight/volume basis) in formic acid. Several blends as
SF10G0, SF2G8, SF3G7, SF5G5 and SF0G10 have been made and their rheological behaviour
was investigated. The blend solutions were subjected to a steady shear rheological study in the
variety of range of shear rates, namely 0.01–500 sec-1 and the viscosities of blend solutions
were noticed to decrease in comparison to pure silk solution. The frequency sweep was employed
in dynamic rheological tests to determine complex viscosity of More >

Journal of Polymer Materials, Vol.40, No.3-4, pp. 285-303, 2023, DOI:10.32381/JPM.2023.40.3-4.10
Abstract The exoskeleton of marine shrimp contains a natural, biocompatible polymer chitin, which is
dumped as a waste. The study proposes the sustainable single-pot-extraction of chitosan from
the waste and its use in the fabrication of wound-dressings, and thus leverage its piezoelectric,
antioxidant, hypoglycaemic and medicinal properties in wound-healing. The Fourier transform
infrared spectrum revealed that marine chitosan contains functional groups with N-O, O-H, and
CO stretching. Scanning electron micrographs demonstrated the spherical and mesoporous
structures of the extracted chitosan. X-ray diffraction analysis showed a semi-crystalline phase
of chitosan particles with a mean size of 28.9… More >
