Employing the design of the experiment (DOE) method and response surface methodology (RSM) allowed tuning and manipulating various dipping protocols in exploring critical factors such as total solid content of the compounded latex, coagulant concentration, and dipping time. As such, the aim is to discern their individual and collective influence on film thickness and subsequently physical properties such as tensile strength and thermal ageing. In this study, the response surface refinement was conducted via central composite design (CCD) using these three factors: total solid content of the compounded latex, coagulant concentration, and dipping time. Based on the regression analysis, the optimum condition for thinner NR films with good tensile strength and ageing properties was achieved with final dipping protocols comprising 20% TSC, 5% coagulant concentration, and 5 s dipping time. The resulting responses from the validation experiments for thickness, tensile strength, and ageing were 0.073 mm, 18.11 MPa and 20.82 MPa, respectively. The implications of these findings are significant for the latex-dipped product sector, particularly in glove manufacturing. They facilitate the creation of cost-effective, thinner gloves while maintaining essential mechanical and ageing properties, which is vital for both medical and industrial uses. The result also shows that, perhaps with extra caution, RSM can be applied effectively in optimising the properties of the dipped film.</p></div>","PeriodicalId":662,"journal":{"name":"Journal of Rubber Research","volume":"28 2","pages":"239 - 253"},"PeriodicalIF":1.5,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145166037","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}

On the basis of deproteinised natural rubber (DPNR), a hydrophilic and water-absorbent polymer network composed of a deproteinised natural rubber-grafted-poly(acrylic acid) (DPNR-g-PAA) system and linear polyethylene glycol (PEG) was designed and fabricated. The graft copolymerisation of DPNR with acrylic acid (AA) was initiated by a redox initiator system consisting of potassium persulfate (KPS) and sodium hydrogen sulfite (NaHSO<sub>3</sub>) under nitrogen, followed by the addition of PEG to the system. The key factors influencing the grafting efficiency of DPNR-g-PAA were investigated, including reaction temperature, mixing time and AA content. The grafting system was finally attached to the hydrophilic polymer PEG. Water adsorption behaviour tests and water contact angle experiments indicated that grafting PAA and linking PEG in DPNR latex increased hydrophilicity. The results indicated that the maximum water absorption of DPNR-g-PAA was 78.24 ± 5.06% and the minimum of water contact angle of DPNR-g-PAA@PEG was 9.58 ± 1.37°.

Styrene-butadiene rubber (SBR) filled with feldspar and CB (SBR/CB-Feldspar) has been used in this study to assess feldspar's potential as a reinforcement filler in tyre tread applications. CB:Silica was compared to CB:Feldspar at a similar ratio to determine the ideal hybrid filler system. For both control and hybrid compounds, this work observed the impacts of different sulphur vulcanisation systems, including conventional vulcanisation (CV), efficient vulcanisation (EV), and semi-efficient vulcanisation (semi-EV).

The findings demonstrate that the semi-EV system reduces the SBR-Feldspar compound’s scorch and cure times. The hybrid compound's curing characteristics and physical properties, such as tensile strength, hardness, rebound resilience, and abrasion resistance, have been enhanced using SBR/CB-Feldspar with the maximum CB content (30 phr). Moreover, further research on optimised hybrid CB:Feldspar composition with various rubbers has been conducted to examine the effects on curing characteristics and mechanical properties of hybrid fillers with the rubbers, including Natural rubber (NR), Ethylene Propylene Diene Rubber (EPDM), Chloroprene Rubber (CR), and Nitrile Rubber (NBR).
