This work investigates the suitability of Borassus flabellifer sprout fiber, a new class of fibers, as reinforcement in polymer matrix composites. Borassus flabellifer sprouts are also called palm sprouts. The fibers were extracted by the water retting method and treated with 5% sodium hydroxide (NaOH) to remove the impurities present in the fiber to achieve better bonding with the matrix. Scanning electron microscopic images of raw and alkali treated Borassus sprout fibers were studied. Composite specimens were made with 20, 25, 30 and 35 volume % of treated and untreated palm sprout fibers, respectively, in a polyester matrix by the hand layup technique and by the compression molding technique. Tensile strength, flexural strength, compression strength, impact strength, hardness and water absorption of sample specimens were determined. Experimental results showed that the composite specimens with 35 volume % of treated palm sprout fibers as reinforcement performed better in all aspects. They have 30.34% higher tensile strength, 34.47% higher flexural strength, 3.14% increased compression strength and 15.56% better impact strength and 7.6% less water absorption than the composite plates reinforced with 35% untreated palm sprout fibers. Thus, the composites showed adequate mechanical properties to be considered for specific applications.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49396522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the reinforcement treatment, the CNF were acetylated before preparing the PLA electrospun solution. The obtained CNF were observed using atomic force microscopy (AFM) and analyzed after acetylation using FT-IR spectroscopy to confirm their modification. Morphology studies on the films were conducted using scanning electron microscopy (SEM). The films were tested via tearing tests according to ASTM D1938 (2014). Besides, the films were subjected to photodegradation experiments according to ASTM D4329 (2013) and to mechanical testing to analyze the influence of photodegradation on their mechanical properties. The addition of 1% CNF was translated into an important increase in tear strength, which in some cases reached a 37% increase.

Hydroxypropylation increased the average diameter of PS, SPS, Ps and WCS, but lowered the average diameter of TS and CS. Carboxymethylation altered the crystalline structure of WCS and CS.

All synthesized membranes were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and scanning electron microscopy (SEM). In the second part, we prepared two new semiconductors n-Sr2Fe2O5 and p-CuFeO2 and their photo-electrochemical characterizations were undertaken. As application, the transport of Pb2+ using synthesized membranes coupled with the synthetized photoelectrodes was studied. The photo-catalytic results indicate that the combined hetero-system n-Sr2Fe2O5/p-CuFeO2 enhances considerably the electrons transfer. The diffusion flux of Pb2+ increases considerably when the electrode is exposed to visible light. The results show that the diffusion percentages of Pb2+ increase by 68% under solar energy and 79% using a LED lamp.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49482171","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biodegradability, flammability and water absorption are the primary disadvantages of wood-based composites, which reduce their service life. In this experimental study, waste colemanite was used to decrease the known flammability of wood composites. Phenol formaldehyde (PF) was used to increase the water resistance and prevent biodegradability of the prepared materials, and hemp fiber was added to increase their mechanical strength. Thus, the objective was to avoid the disadvantages of wood-based materials. Based on the results of the flexural strength test, the optimum polymer composite material production parameters were determined to be as follows: 0.50 filler/binder ratio, 56 kg/cm2 moulding pressure and 0.75 hemp fiber ratio. According to the results of the experiments, the use of waste colemanite in the production of composite materials improves their non-flammability, while decreasing flexural and screw withdrawal strengths. It was determined that waste plum pits could be used to substitute for wood chips, as an alternative filler material in the production of composite materials. As a result, eco-friendly polymer composite materials were produced from waste plum pits, hemp fiber, and waste colemanite. The obtained composite materials are compliant with applicable standards and are suitable for application as building materials for use in both interior and exterior space.","PeriodicalId":10130,"journal":{"name":"Cellulose Chemistry and Technology","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42482485","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
