Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a free service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are accessible to all readers and citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

Facile Synthesis of Tunable and Durable Bulk-Superhydrophobic Material from Amine ‘Reactive’ Polymeric Gel By Adil Majeed Rather and Uttam Manna* [*] Adil Majeed Rather, Uttam Manna Department of Chemistry Indian Institute of Technology-Guwahati, Kamrup, Assam 781039, India E-mail:
[email protected] Keywords: Superhydrophobicity, polymeric material, self-cleaning, oil/water separation, post functionalization Materials with extremes of water wettabilities are of potential interest in various fundamental and applied contexts. However, more often, poor chemical and physical durabitity of conventional thin special wettable materials hold back several prospective applications of this property at practical settings. A chemically ‘Reactive’ polymeric gel material is introduced here by taking advantage of robust and facile 1,4- Michael addition reaction between acrylate and primary amine groups, to develop a chemically cross-linked and bulk (including interior and surface) superhydrophobic material. Mixture of dipentaerythritol pentaacrylate and branched poly (ethyleneimine) (BPEI) can rapidly form self-standing gel network. On removal of solvent molecules, the synthesized gel network provides a highly porous and reactive polymeric matrix that can be further post modified with variety of small molecules to tailor the liquid water wettability on the synthesized material. This approach provides a facile and rapid process to fabricate a bulk (internally) superhydrophobic material with complex shapes and arbitrary size. The property of the material remains intact even after imposing various standard chemical and physical insults. This synthetic strategy could be useful in developing advanced and multifunctional materials for further broadening the advance applications of this anti-wetting property including oil/water separation, self-cleaning, sustaining and slow drug release etc.
