Mucoadhesive polymer owing to its binding capacity with gastric mucin prolongs the gastric residence time and thereby increased drug bioavailability. In the present study, oral controlled release mucoadhesive matrix tablets have been developed for domperidone as model drug using natural mucoadhesive material myrrh oleo gum resin (MOGR).The tablets were formulated with the natural polymer in dif...

Incorporating superabsorbent polymer (SAP), which has the abilities of absorption and desorption in concrete can achieve the effect of internal curing. The influences of the volume, particle size and ways of entrained water of SAP on the workability, compressive strength, shrinkage, carbonation resistance and chloride penetration resistance of concrete were analyzed through the macroscopic and ...

Natural polymers are widely used in pharmaceutical formulations. They are biodegradable and generally nontoxic in nature. In this review pharmaceutical application of rosin is characterized. Rosin is a natural non-volatile resinous mass obtained from Pinus palustris. Physico-chemical characteristics and ease of availability of rosin provide a platform to use it as a polymer for different drug d...

Dynamic TG analysis under nitrogen was used to investigate the thermal decomposition processes of 10 types of natural fibers commonly used in the polymer composite industry. These fibers included wood, bamboo, agricultural residue, and bast fibers. Various degradation models including the Kissinger, Friedman, FlynneWalleOzawa, and modified CoatseRedfern methods were used to determine the appare...

In this study, a polymer-silica nanocomposite using the sol-gel method was synthesized in three steps at room temperature. The nanocomposite material was formed with an organic compound (polyethylene glycol) and inorganic silica nanoparticles. Furthermore, the size and the distribution of nanoparticles in the polymer matrix were characterized by a transmission electron microscope (TEM).  In add...

Polymer composites based on natural fillers are currently attracting great attention as alternative materials to glass or synthetic fibre reinforced plastics in several applications, mostly for automotive, appliance and packaging products. The main advantage of employing natural fibres is that these are biodegradable and renewable, and exhibit low cost, low density and high toughness. However t...

Today, the use of natural polymers and their replacement with synthetic polymers in various fields of science has attracted much attention. Reducing the associated risks, easy access, and being cost-effective are among the advantages of using natural polymers compared to the synthetic polymers. In this research, the destruction of amylopectin in the presence and absence of titanium dioxide nano...

The main objective of the work is to prepare mefenamic acid loaded microspheres for sustained release using different polymers ethyl cellulose as synthetic polymer and sodium alginate as natural polymer and compare and selecting best suitable polymer among them. For preparing mefenamic acid microspheres ethyl cellulose used as synthetic polymer in solvent evaporation method and sodium alginate ...
