Self Healing

Ujian merupakan keniscayaan dalam hidup setiap manusia, ujian akan selalu melekat pada seseorang sedari lahir ke dunia hingga ia menemui ajalnya. Datangnya cobaan kepada kita inilah yang akan dirasakan sebagai suatu stres (tekanan) dalam diri. Stres memiliki tingkat yang berbeda pada setiap individu, hal ini dipengaruhi oleh pemaknaan individu tersebut terhadap pemicu stres dan bagaimana coping yang dilaukan oleh individu tersebut. Salah satu coping yang efektif untuk dilakukan adalah self healing. Penelitian ini merupakan penelitian kepustakaan terhadap kitab Minhajul ‘Abidin karya Imam Al Ghazali. Adapun temuan dari penelitian yang dilakukan adalah: terdapat tujuh tahap self healing terstruktur dalam mengatasi stres dalam kitab Minhajul ‘Abidin Imam Al Ghazali, yaitu mengenal diri, menerima diri, mawas diri, melepaskan, merefleksikan dan bersyukur

<p>Design of materials with novel sensitivities and smart behaviour is important for the development of smart systems with automated responsiveness. We have recently reported the synthesis of hydrogels, cross-linked by <i>N,N'</i>-diallyltartardiamide (DAT). The covalent DAT-crosslinking points have vicinal diols which can be easily cleaved with periodate, generating valuable a-oxo-aldehyde functional groups, useful for further chemical modification. Based on those findings, we envisioned that a self-healable hydrogel could be obtained by incorporation of primary amino functional groups, from <a>2-aminoethyl methacrylate </a>hydrochloride (AEMA), coexisting with DAT into the same network. The a-oxo-aldehyde groups generated after the reaction with periodate would arise in the immediate environment of amine groups to form imine cross-links. For this purpose, DAT-crosslinked hydrogels were synthesized and carefully characterized. The cleavage of DAT-crosslinks with periodate promoted changes in the mechanical and swelling properties of the materials. As expected, a self-healing behavior was observed, based on the spontaneous formation of imine covalent bonds. In addition, we surprisingly found a combination of fast vicinal diols cleavage and a low speed self-crosslinking reaction by imine formation. Consequently, it was found a time-window in which a periodate-treated polymer was obtained in a transient liquid state, which can be exploited to choose the final shape of the material, before automated gelling. The singular properties attained on these hydrogels could be useful for developing sensors, actuators, among other smart systems.</p>
