Chemical Modification of Chitosan-Filled Polypropylene (PP) Composites: The Effect of 3-Aminopropyltriethoxysilane on Mechanical and Thermal Properties

Mechanical and thermal properties of coconut shell powder filled polylactic acid biocomposites: effects of the filler content and silane coupling agent

“…However, treating the CSP with 3-APE led to an increase in the tensile strength of the PLA/CSP biocomposite, as the long alkyl chain of 3-APE covalently and hydrogen bonded to the surface of CSP via silane, which increased the hydrophobicity of CSP and thus enhanced the interfacial adhesion between the CSP and the PLA matrix. Some researchers have also found that 3-APE enhances the properties of PP/chitosan [16] and PP/wood [19] composites in a similar manner. The elongation at break of the PLA/CSP biocomposites decreased dramatically with filler content, as shown in Fig.…”

“…a % based on weight of CSP [16] Differential scanning calorimetry (DSC) analysis DSC analysis was particularly useful for determining the glass transition temperature (T g ), crystallization temperature (T c ), melting temperature (T m ), and the crystallinity (X c , in %) of each biocomposite. DSC analysis was carried out by using a Q10 DSC (TA Instruments, New Castle, DE, USA).…”

“…Silane can be successfully used as a coupling agent for both inorganic fillers and natural fillers, such as bamboo fiber [13], oil palm empty fruit bunch fiber [14], wood flour [15], chitosan [16], and banana fiber [17].…”

Chemically Chitosan Modified With Methyl Methacrylate and Its Effect on Mechanical and Thermal Properties of Polypropylene Composites

“…A number of attempts have been carried out in order to enhance the interaction between chitosan fiber and hydrophobic matrix. Salmah et al [21] reported that the interfacial adhesion between chitosan and PP matrix was significantly enhanced by employing the 3-aminopropyltriethoxysilane (3-APE) as the chemical modifying agent in composite systems. In addition, in our previous work we have reported that better interfacial bonding and higher tensile strength of chitosan filled polypropylene (PP) composites were obtained by chemically treating the chitosan with sodium dodecyl sulfate [22].…”

Fabrication of EPDM Rubber/Organo-bentonite Composites: Influence of Hydrochloric Acid on the Characteristics of Modified Bentonite and Final Products

“…[3-(2-Aminoethylamino)propyl] trimethoxysilane (AEAPTMS) was selected as the modifier due to its two amino groups in the functional groups leading to strong interaction with the polymer molecules in the rubber matrix. Previously, there were already some reports on the amiable treatment of silicate [18][19][20] or other potential fillers [21][22][23][24][25] with silane coupling agents before compounding with rubber compounds. However, there is still few research work focusing on the important factors in the synthesis influencing on the catalyzation of the hydrolyzation and condensation between AEAPTMS and bentonite in alcohol-water system, the structure of bentonite as well as even the performances of final rubber composites.…”
