It has an easy functionalization, dispersion, adsorption and swelling properties. The PGMA was effectively used as a precursor for the development of many novel and advanced materials with enhanced properties lead to diverse applications. For instance, the incorporation of nanoparticles in PGMA exhibited progressive properties. Nevertheless, homogeneous distribution of nanoparticles in polymers is not that much simple due to their tendency to get aggregate. Whereas, the homogeneous distribution of nanoparticles in the PGMA is quite easy due to its grafting ability. The design, development and characterization of PGMA based novel materials for improved properties and apply those materials for diverse problems has gained a great interest among the researchers from the past one decade. This review highlights the insights on different methods of preparation of PGMA based materials to attain the desired properties and provide useful information about the characteristic features of the PGMA microspheres. This review also useful to evaluate some of the key aspects for the development of PGMA based materials and endow with new possible ways and ideas to take up some innovative research.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 6","pages":"593 - 615"},"PeriodicalIF":1.0,"publicationDate":"2024-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139758693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To replace these synthetic materials, high-strength biodegradable polymer composites of Pectin, Luffa Fiber (agro-waste) and Glycerol are synthesized by the solvent casting technique using a universal solvent. The experimentation is carried out using a 3 × 3 factorial design and the tensile behavior (tensile strength and elongation) of composites is analyzed by response surface methodology (RSM). The tensile strength of pectin containing 10% glycerol is 11.48 MPa which is increased to 19.34 MPa by incorporation of 15% luffa fiber and this composition is optimized with desirability index method (simultaneously optimization) to achieve the best results for elongation at break (188.89%) as well. The interactions between constituents of composites are characterized by FTIR spectro-scopy and scanning electron microscopic study reveals a uniform distribution of fiber. The composites have sustained thermal stability as all composites are stable up to 260°C in an inert atmosphere under TGA study. The biodegradability of composite films was observed by soil burial method and found completely degradable in 75 days. The present composites of non-toxic components with high tensile properties, sustained thermal stability and complete biodegradability are suitable for green packaging applications.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 5","pages":"557 - 567"},"PeriodicalIF":1.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138567615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The thiophene-derived compound that was abbreviated as (T) was synthesized, and (CT-C8) was obtained by adding of (T) to the starting compound (C-C8). Additionally, the electrochemical polymers of CT-C8 were synthesized and accumulated onto different surface types such as an indium tin oxide (ITO) coated glass, aluminum (Al) layer, copper (Cu) sheet and pen tip electrode (PTE). The electrochemical syntheses of the polymers were performed by using 0.05 M NaClO4 as an electrolyte in acetonitrile (AN) solvent. The electrochemical behaviors of the polymers were also investigated by taking the cyclic voltammeric measurements with a triple electrode system, and the electrochemical behaviors of the coated polymers on different electrode surfaces were also researched in the presence of Fe3+ and Fe2+ metals. According to the obtained voltammogram results, it can be said that the electrochemically synthesized polymers on different electrode surfaces were sensitive to Fe3+ metal and they could be used as an electrochemical sensor for all electrode surfaces as mentioned above. For the performed electrochemical measurements, the oxidation and reduction peak values obtained for different electrode surfaces were different from each other. When it is desired to examine the electrochemical property of a material, there is a need to search for more useful and economical insoles, since the conductive surface like ITO is deformed after repeated applications and expensive. This study, which offers an alternative conductive base to replace ITO, is important in this regard.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 5","pages":"488 - 503"},"PeriodicalIF":1.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been found that the isolated fractions contain branched polysaccharides in the form of complexes with melanin. After purification of polysaccharides by ion exchange chromatography from locally growing and cultivated basidial raw materials, two fractions have been obtained: neutral polysaccharides of locally growing Ganoderma lucidum (GW-1), cultivated Ganoderma lucidum (GWL-1) with a yield of 25.71 and 29.85%, respectively, and anionic polysaccharides of locally growing Ganoderma lucidum (GW-2), cultivated Ganoderma lucidum (GWL-2), with a yield of 5.26 and 4.19%. The physicochemical properties of the obtained samples have been studied by IR and UV spectroscopies. The purity degree of fractions of branched polysaccharides has been determined. Using gas chromatography, one-dimensional (13C NMR, 1H NMR), and two-dimensional (COSY, TOCSY, HSQC, HMBC, NOESY) NMR spectroscopies, the compositions and molecular structures of the obtained polysaccharide samples have been determined. The results showed that the isolated and purified polysaccharides are β-glucan-type branched polysaccharides that have branch point (1,4,6)- and (1,3,6)-linked glucopyranose residues.","PeriodicalId":738,"journal":{"name":"Polymer Science, Series A","volume":"65 5","pages":"522 - 532"},"PeriodicalIF":1.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138516542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
