T1 - Combining phage display and next-generation sequencing for materials sciences: A case study on probing polypropylene surfaces JF - Journal of the American Chemical Society N2 - Phage display biopanning with Illumina next-generation sequencing (NGS) is applied to reveal insights into peptide-based adhesion domains for polypropylene (PP). One biopanning round followed by NGS selects robust PP-binding peptides that are not evident by Sanger sequencing. NGS provides a significant statistical base that enables motif analysis, statistics on positional residue depletion/enrichment, and data analysis to suppress false-positive sequences from amplification bias. The selected sequences are employed as water-based primers for PP-metal adhesion to condition PP surfaces and increase adhesive strength by 100% relative to nonprimed PP.

T1 - Multiple-sample approach for bonding and testing: validation of bonding strength of adhesive-bonded joints and adhesive tapes T2 - EURADH 2016 Adhesion ´16 N2 - The multiple-sample approach by means of centrifugal adhesion testing (CAT-technology) allows the determination of bonding strength of adhesive-bonded joints on a statistical basis of up to eight samples. Therefore, it is obvious to ensure the continuous handling and identical processing of an octet of samples within the entire process chain of wet-chemical cleaning, plasma-chemical pre-treatment, bonding of samples, and testing of bonding strength. Within the multiple-sample bonding set-up (MPKV-technology) a defined bonding pressure can be adjusted regardless the actual number of samples. A comparison of single- and multiple-sample approach is made for bonding strength of selected adhesives, double-sided adhesive tapes and different material combinations [stainless steel (V2A) vs. stainless steel, polyamide (PA), or polypropylene (PP)]. It is shown that both technologies improve reliability of results T2 - EURADH 2016 Adhesion ´16 CY - Glasgow, UK DA - 21.09.2016 KW - Multiple-sample bonding KW - Multiple-sample testing KW - Bonding strength KW - Adhesives and adhesive tapes PY - 2016 SP - 162 EP - 166 AN - OPUS4-37588 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER - TY - CONF A1 - Rietz, U.

T1 - Quantitative determination of adhesive tape properties by CAT-technology (centrifugal adhesion testing) T2 - EURADH 2016 Adhesion ´16 N2 - The future commercial prospects for adhesive tapes are very good and its application range is very broad. From every-day-use in office, packaging, maintenance, and quick repair in workshops, it ranges from handicraft work, medical purposes and cosmetics up to workmanship. The study describes a new multi-sample approach in adhesive tape testing from theoretical background, preparation of test specimen for tensile as well as shear testing, detailed measurement procedures up to analysis and result interpretation. Various types of single and double-sided pressure sensitive adhesive tapes supplied by different manufacturers were investigated and compared T2 - EURADH 2016 Adhesion ´16 CY - Glasgow, UK DA - 21.09.2016 KW - Tensile KW - Shear KW - Peel KW - Strength KW - Analytical centrifugation KW - Adhesive tapes PY - 2016 SP - 352 EP - 355 AN - OPUS4-37664 LA - eng AD - Bundesanstalt fuer Materialforschung und -pruefung (BAM), Berlin, Germany ER -
